EDITOR’S LETTER

T

he pandemic has undoubtedly affected all aspects of our lives and all economic sectors alike, including the corrosion prevention one.

Contrary to what one might think, however, not all of its effects have been

negative. Apart from the devastating impact of the supply chain failure, which is still a major problem also in terms of rising raw material costs, some trends have emerged (partly exposed by an article from “The Coating Inspector” blog, which you will find at the beginning of this magazine) that are forcing companies to hit the gas on R&D, with undoubted benefits on the evolution of anti-corrosion coating (passive protection) systems.

One of them is the demand for greater efficiency, durability, and effectiveness of paints.

Alongside this is the opportunity-turned-need to reduce dependence on oil derivatives for the formulation of coatings, as well as to reduce VOCs. Epoxy paints (largely derived from renewable resources and therefore more sustainable) thus got centre stage, even offering the possibility of incorporating additional properties (antibacterial, for example).

The use of water-based coatings is also gaining ground in sectors traditionally associated with the use of solvent-based systems, such as the oil industry. A fascinating case study on valve coating by a well-known Italian company bears witness to this. The spread of powder coatings in parallel with that of water-soluble products also proves that it is possible to reduce VOCs without sacrificing performance, which is crucial in the

anti-corrosion sector. This move away from traditional high-solvent technologies is also evident in the marine sector, with the latest generation of anti-fouling paints.

Finally, this issue of ipcm_Protective reiterates once more the importance of surface preparation for a high quality, durable, and fully functional anti-corrosion coating: we deal with this in an extensive article analysing the available mechanical preparation processes and in another chapter of our “Inspection LogBook”.

Unfortunately, we will have to wait until 2022 to see all these technologies on display at a trade fair open to professionals. This is yet another disheartening negative effect of the pandemic: all strategic exhibitions planned for 2021 have been postponed to 2022 or turned into online events, which however tend to lack the power of relationships and networking that underpins a trade fair’s success.

Hopefully, this is the last time we will have to talk about this aspect of the pandemic on social and commercial relations.

urface preparation of steel before external coating application is the foundation of any corrosion control program. Any

compromise made in the degree of surface preparation will usually compromise the field applied coating performance as well, regardless the technical quality of the pipeline coating. Surface preparation is defined as the cleaning and/or pre-treatment of the metal and adjacent coating surface ensure the best possible bond between the surface to be coated and the coating to be applied.

Coating degradation problems that lead to the creation of a corrosion risk within the design life of a pipeline can be attributed to one of the following causes: • An inappropriate specification for the coating material and/or

coating process • Poor surface preparation and/or application • Interaction with the operating environment.

Poor surface preparation and poor coating application practices can lead to premature coating degradation, particularly loss of adhesion, and increased risk of corrosion. Appropriate standards have been well defined for many years but do not appear to be applied, or applied correctly.

There are many degrees and methods of surface preparation ranging from simple dusting or blowing away of loose dirt and rust, to the complete removal of all contaminants. The methods include the use of steam cleaning, laser cleaning, oscillation cleaning, chemical cleaning, hand tools, power tools such as grinders and needle guns, bristle blasting, water-jetting and loose abrasive blasting for e.g. loose abrasive grit blasting or sponge-jetting.

Preparation grades as included in ISO 8501-1 (Sa 1.0 – 3.0) have been used for many decades to describe the surface cleanliness level achieved by the abrasive blast cleaning method as described in ISO 8504-3. Blast-cleaning grade Sa 3 is deemed as the cleanest possible surface finish from the blast cleaning method and it is normally produced in a plant-applied pipeline coating

environment using engineering controls and automated blast cleaning machines with metallic abrasives.

Blast-cleaning grade Sa2½ is typically achieved on working sites, where access is sometimes difficult and temporary provisions such as encapsulation, heating and dehumidification are used to control the works.

An important rule to remember when selecting both the degree and method of surface preparation is that the service and life expectancy of a given field joint coating or coating system is directly proportional to the degree of surface cleaning done prior to field joint application.

Prepare what’s important The first objective of surface preparation is to remove surface contaminants that will affect the performance of the pipeline coating. Some of these are: • oil and grease. These can inhibit good coating adhesion and should completely be removed • soluble salts. These can increase moisture penetration by osmotic pressure through the coating and can accelerate the rate of corrosion • dust and dirt. These can inhibit good coating adhesion • rust usually cannot be penetrated by most coatings resulting in uneven layers with exposed metal where corrosion can take place • mill scale. These cannot be penetrated by most coatings and will eventually break free from the substrate taking any coating with it

• delaminated coating can be present at edges-backs and can inhibit corrosion prevention.

The second objective is to remove surface imperfections in accordance with the ISO 8501-3. Some of these are: • weld spatter • sharp edges • burrs • slivers • pits • crevices.

Grinding of steel defects shall not reduce the wall thickness below the specified minimum wall thickness of the pipe.

Wire brushes have good resistance to wear and tear.

• Reciprocating impact tool (needle gun) - this tool consists of a group of steel needles that are struck by a piston, like a chisel. The needles project out of the gun simultaneously and they will strike the surface individually and hence adapt to irregular surfaces. This is most effective on brittle or loose surface contaminants.

that enables formulating more eco-friendly, cuprous oxide containing anti-fouling coatings. VP 4200 is tailor made for both CDP (Controlled Depletion Polymer) and SPC (Self-Polishing Coating) coatings.

Thanks to its ability to form a complex with Cu2O, VP 4200 ensures

a better control of the release of the biocide. The performance is

guaranteed by its formulation with only 10 pbw% cuprous oxide and 4 -6 pbw% VP 4200, which leads to the same performance as the standard type with up to 50 pbw% Cu2O.

VP 4200 has a relatively low thickening effect, so higher amounts can easily be incorporated into the systems, especially in combination with TEGO® Dispers 1010.

Spray Galvanising as Essential for Motorist Safety Numerous accidents have been caused by the corrosion of bridge and tunnel support structures. Hot spray galvanising is a useful protective solution that ensures that both structural and non-structural elements have a service life of more than 80 years.

T

he death of a truck driver in the Lehigh tunnel in Pennsylvania (USA), occurred

on February 21, 2018, was caused by the detachment of a lighting fixture from the vault due to the breaking of a corroded support bracket. The analysis conducted by the Federal Highway Administration (FHWA) confirmed that the PVC coated bracket was completely corroded. Subsequent inspections found that other similar support systems were corroded and these were immediately replaced.

It is worth noting that spray galvanising is the most effective corrosion protection system in such highly corrosive environments, not only for structural elements, such as the iron reinforcements of reinforced concrete, but also for non-structural ones, including lighting systems, sign posts, gutters, etc. Indeed, spray galvanising is the only system that enables to apply zinc coatings up to 300-500 microns, guaranteeing a service life of more than 80

An example of the CUI phenomenon.

Providing additional reassurance An inert multi-polymeric matrix type material, the Versiline CUI 56990 coating contains a silicone backbone that delivers a high temperature resistance. This means that in combination with its unique fibre-reinforced filler package, it is applied in thicker films and has superior barrier properties than thinner film silicones, which offer limited corrosion protection.

The coating is formulated for resistance against temperatures of between -196 and up to 650°C, making it suitable for all types of assets processing hydrocarbons where corrosion under insulation can occur.

An additional advantage with inert multi-polymeric matrix type materials is simplicity for applicators. Inert multi-polymeric matrixes can be specified for several temperature and performance categories, making them ideal for bulk items such as pipework and valves, or any items where the exact operating temperature may not be known at the design stage.

ITF, a company active in the production of shot blasting, industrial cleaning, and deburring equipment, has developed very innovative, advanced automatic shot blasting lines for electric water heaters that have already been installed all over the world. These are highly efficient and they can be easily integrated with downstream process steps (i.e. enamel application and curing), thus creating fully automatic enamelling plants manned by a few operators who handle the loading and unloading of tanks.

Main features of the automatic shot blasting system Electric water heaters consist of a carbon steel tank with an enamelled inner surface. Shot blasting enables the tank’s metal surface to be properly prepared for subsequent enamel deposition, especially when using the powder enamelling technology. The plant developed by ITF is a multi-station system (four or more, depending on production requirements) with a step-by-step movement that does not involve rotation of boilers.

After being loaded onto the overhead conveyor, the tank stops at an external station where sensors perform a dimensional check to select the most appropriate shot blasting recipe; this includes specific movements for each lance, which depend on the tank’s diameter and

orroded reinforcement is the chief cause of concrete deterioration, which prompts

subsequent repairs. For repairs to be sound, contractors must ensure adequate adhesion of new patch repair materials by proper preparation of exposed reinforcing steel, which should be free of any materials such as concrete, dirt, and corrosion products that could interfere with repair material adhesion, although a tightly bonded light rust on the rebar surface is usually not detrimental to the bond of patch materials.

To tackle this challenge and mitigate rebar corrosion, Cortec has developed CorrVerter® MCI® Rust Primer, which can be applied to

rusty or poorly prepared steel surfaces where further corrosion protection is required and good surface preparation is difficult to achieve.

CorrVerter® MCI® is a formulation of chelating agents combined with a high-solid waterborne latex with extremely low water vapour permeability. This fast drying, singlecomponent primer converts surface rust into a hydrophobic passive layer and offers excellent protection against re-rusting of metal surfaces. Reinforcement coated with CorrVerter® MCI® Rust Primer has similar bond strength to concrete compared with uncoated rebar.

CorrVerter® MCI® Rust Primer data reports 500 hours of corrosion resistance in salt spray testing (ASTM B-117) at only 3-5 mils (75-125 µm) DFT (applied at 8.7-14.5 mils [217.5-362.5 µm] WFT).

Assured Corrosion Protection for Wind Energy Units Laura Saure Dörken Coatings GmbH & Co. KG – Herdecke, Germany coatings@doerken.de

High-performance corrosion protection for screwed fasteners in high-tensile steel enables wind energy units to be largely maintenance free. Zinc flake systems have proven their reliability in the area of rotor blade fastenings for over 30 years.

T

he rotor blades are fundamental, key components of a wind energy unit. They are used to extract energy from flows of air and

move this to the generator. The blade lengths of up to 85 metres and a weight of up to 25 tonnes mean that the fastening of the rotor blades to the rotor hub is particularly significant. This is achieved using fasteners, consisting of so-called double ends, barrel-nuts and hexagonal nuts, typically in the M30 to M36 dimension range.

Diverse stresses and requirements The rotor blades and thereby also their screwed fasteners are subjected to extreme climatic as well as dynamic stress from wind load and the operation of the unit itself. This is joined by static forces from prestressing of the bolts and the mass of the connected elements. As a consequence of the high level of stress for the screwed fasteners, the choice of corrosion protection is especially important.

The protective coating needs to meet specified coefficients of friction in order to guarantee problem-free fastening on the construction site, typically with considerable time pressure and under difficult conditions. In addition, the coating must offer highly-effective and long-lasting corrosion protection to ensure the long-term, reliable operation of the unit.

Corrosion protection with multiple benefits The best solution is therefore a coating system like the extremely thin zinc flake coatings from Dörken. They fulfil all of these requirements and consist of a basecoat and an organic or inorganic topcoat tailored to the respective components. The zinc-containing basecoat determines the corrosion properties and is responsible for the cathodic corrosion protection. In addition to adding further protection, the tailored topcoat enables the observance of defined coefficients of friction and therefore safe and fast assembly.

The VOC emission can be reduced from 120 g/m² to 20 g/m² compared to a common solvent borne coating system.

This reduction not only protects the substrate, it also protects the environment. The eco-friendliness is obvious, because of the reduced coating thickness and hence less material using less solvents (Table 2).

Test results The corrosion protection performance was investigated with coatings on blasted steel, according to DIN EN ISO 12944-6 (C5 high, test program 1).

A standard three-layer coating, a commercial 2-pack zinc dust epoxy-primer, a 2-pack epoxy-intermediate layer, and a 2-pack polyurethane top coat (in total: 280 µm dry film thickness, Fig. 2a) were compared to the two-layer combination of the waterborne silane-primer with the 2-pack silicone hybrid top coat (in total: 185 µm dry film thickness, Fig. 2b). In the humidity chamber test, carried out according to ISO 6270-1, no difference could be detected. Both coating systems showed no blistering after 720 hours exposure. However, the adhesion on the two-layer system was better (GT 0-1 versus GT 2).

Another advantage, which is achieved with top coats based on silicone hybrids, is the higher chemical resistance. The coating was exposed at room temperature to 10% solutions of sodium hydroxide and of sulfuric acid; no damage was evident on the paint surface. Surfaces based on silicone hybrids also show a good performance in terms of easy-to-cleanproperties and good abrasion resistance.

Summary The high crosslinking of coatings based on a silicone hybrid resin qualifies this binder-technology for highly durable coatings - extraordinary gloss, colour retention and weather resistance. Compared with a conventional © Evonik

© Evonik

three-layer system, this two-layer system has better corrosion protection, even though the dry film thickness is 95 µm less.

In combination with the waterborne zinc dust primer, based on silane, we achieved an eco-friendly coatings system, which offers a brilliant solution for the reduction of solvents and material and thus the reduction of costs and additionally provides a long-lasting protection against the formation of micro-channels. ‹

We will begin with the “water cleaning” method. This is often used in the preparation of both metal and cement surfaces, using quality-controlled industrial water that can be heated and used with the addition of a detergent, which optimises the cleaning action, or with abrasives, which can be injected into the water flow – in this case, the correct term is “water blasting”.

B2B Marketing: How to Set Up an Effective Multichannel Strategy Ilaria Paolomelo eos Mktg&Communication Srl

info@eosmarketing.it

Cross-media marketing has always been considered a key factor in ensuring the effectiveness of a corporate communication strategy. But how to set up a multichannel marketing strategy, especially in a sector like B2B, which is dominated by more complex promotion, sales and purchasing dynamics? How to choose the online and offline channels that best suit our needs?

The answer is simpler than one would think:

located in different points of the production chain, stood by and watched, perhaps due to its very technical and specialized nature, which often requires a more conventional approach to selling and buying.

But digital transformation was not (nor will it be) the only event that changed the way we communicate.

In fact, the spread of the COVID-19 pandemic has led us to an almost paradoxical reflection: if on the one hand digital transformation is the future, on the other digital and non-traditional means of communication are actually still essential today1 and the desire for a return to the past and to forms of communication capable of filling the informational gap perceived online and widened with the pandemic, prevails.

From newsletters to podcasts, from technical and specialized magazines up to trade fairs and events: what we thought we could easily replace with increasingly advanced, almost futuristic forms of digitization, still plays a https://eosmarketing.it/en/social-media-trends-2021-theultimate-guide/
