Aluminium curtain Walling restoration BROMOCO systems provide possibly the only successful long term solution to restoring aluminium finishes in situ, and produce ALL the products required to deep clean, prepare, restore and protect all elements of curtain walling and cladding. The only other long term solution has been to replace or remove, strip, re coat in the factory and refit.

BROMOCO systems offer an on-site process that will return the colour and finish back to its original state whilst providing long term protection from re-fade and corrosion, due to the EVB23309E finishing hard coatings built in U.V blockers and antioxidants.

EVB23309E is a hard coating 5 to 7 microns thick with a scratch resistance equal to the original protective surface. It is resistant to airborne pollution, acids, bleaches and bird droppings. EVB23309E is guaranteed not to crack, peel or yellow resulting in long term durability. EVB23309E Protective Coatings will bring back the colour and lustre of old, faded metal and will protect from the damage that the sun, salt air, acid rain, moisture and other damaging elements can cause. EVB23309E also restores the original colour, lustre and shine and is maintainable indefinitely. There are some products that claim to restore the finish such as waxes, silicones and nano coatings that provide a film protection, but no protection from U.V. and there effects are very short term as shown below.

Painting Aluminium Painting is just not a viable or economical solution. If paint is correctly applied the preparation and application process is extremely time consuming and costly. The results of the paint finish can often be unacceptable and will fade over time. Painting is just not a viable or economical solution.

Wax, nano coat or silicon “WNS films” We have conducted several tests previously on WNS films and have found them to provide NO form of protection against UV or oxidization and have a very short life span (Usually one summer). These products also shrink, stain and chalk the surface and in most cases are extremely difficult to remove especially after they have been baked on. As a result of our testing we strongly advise against the use of these products on external facades, cladding and curtain walling components. However these products may be ideal for polishing internal elements that are not exposed to the elements. The wax based films are extremely soft and remain sticky for some time and also when heated in the sun and attract dirt particles to stick to the treated surfaces. We also found that a good quality finish on larger areas such as cladding panels, was almost impossible to achieve as the soft films exhibited swirls and wipe marks. The photo’s to the right shows example deterioration of wax based coatings after only a short period on time (1 summer).

Powder Coated Aluminium

EVB23309E Protective Coating has extra UV Blockers and Anti-Oxidants in it to prevent chalking, fading, oxidation and corrosion and is graffiti resistant. Sealed surfaces are clean up easily with mild soap and water. Metals stay cleaner longer, show less fingerprints and will be much easier to maintain with less effort and time. SATIN FINISH - Some painted metals look better without a gloss finish but still need protection. EVB23309E is also available in a Satin Finish. A Satin Coating can dull the shine on overly shiny metal.

Bare or Milled finishes Mill and bare finishes are relatively rare but can be found on buildings 25 or 30 years old. Due to the nature of the rough surface the level of contamination is generally high. Correct deep cleaning prior to coating is therefore essential. Bromoco Systems provide a bespoke solution for the deep clean and preparation of this surface. Only when the surface has been deep cleaned to a satisfactory level can the application of EVB23309E completed.

Milled or bare aluminium surfaces coated with EVB23309E are fully protected and sealed resisting dirt ingress and repelling water. For further information please visit our website www.bromoco.co.uk

Corrosion of Stainless Steel Tea staining of stainless steel surfaces Tea staining of stainless steel surfaces can be a problem where there are significant levels of chlorides in the water that comes into contact with the metal surface. This can be around the coastal fringe, or in the interior where ground water contains significant chlorides. Although it does not look very pleasant it tends to be a surface phenomenon only, and does not affect the structural integrity or longevity of the material. The cause of tea staining has been examined in some detail to help evaluate the potential remedies for the condition. Recommendations to help prevent tea staining include correct specification of the grade of stainless steel to be used, and surface finishes helping reduce the problem, as well as maintenance procedures, and preventative coating treatments.

How is tea staining caused? Although research on the root cause of tea staining has been limited, with the notable exceptions of work by ASSDA, and an article by Sussex and Gouch (2) there seems to be much research on the root cause of tea staining. However the mechanisms involved can be inferred by the pattern of the corrosion, and known factors that can help counter the effect. One of the most common factors linked with tea staining is the surface finish of the material. Smoother, polished surfaces often do not show any signs of staining, so from this it can be said that grooves or troughs in the material are a root cause of the problem. Surface roughness (Ra) is measured in units of microns (Âľm), and is defined as the average deviation of the height of the surface from the mean height. This is shown in figure 2. Higher Ra values or irregular profiles are often associated with increased tea staining. It is reasonable to assume that the base cause of this corrosion is similar to that of many of the other common Mean Height

types of corrosion. The association of tea staining with proximity to salt water means that chloride attack is the most likely cause of the problem. However you would not normally expect the low level of chlorides present in sea

Fig 2 - Surface Roughness

water, for example, to have such a dramatic effect. The reasons why this occurs can be deduced by the locations and one of the solutions to tea staining problems.

One of the most common ways to prevent problems associated with tea staining is to ensure that the surface is washed regularly with fresh, clean water. This would infer that the corrosion is being caused not by the initial contact with salt water, but with deposits of salt building up on the surfaces. Figure 3 shows how the chloride concentration would build up in any surface troughs. On the left of the diagram the dry condition shows no salt deposition so when wet (the lower line) chloride concentration and therefore corrosion rates are low. As the water evaporates it leaves a deposit of salt in the trough, and the next time the surface becomes wet this deposit concentrates the chlorides naturally present, and increases the corrosive effects. Over time therefore the chloride concentration in these troughs can become high enough to cause corrosion. Note that this would be consistent with the effect that an increasing surface roughness will have on the tea staining effect, i.e. a deeper groove will trap more salty water, which will give a higher chloride concentration. The location of particular areas prone to tea staining also implies that higher temperatures and humidity have an effect, as does

PR_Inserts.indd 9

18/03/2014 09:38


intermittent exposure (for example, spray from rough seas). High temperatures increase the rate of corrosion, but elevated humidity will increase the time taken for the water on the surface to evaporate, and hence increase the time that the higher concentration chloride solution will be in contact with the metal, and it is this contact with the solution that causes corrosion rather than with the resultant solids. Intermittent exposure to salt water also seems to be another major factor, and it can be assumed that this is a two-fold problem. As shown above the cycle of water evaporation is required to deposit the salt on the surface, but also after a single ‘wetting’ as the water evaporates the results in increasingly high concentration of chlorides with time, and therefore an increasingly corrosive solution. Figure 4 shows this in more detail. As the salt water is originally washed into the trough the concentration is fairly low, but as the water begins to evaporate, it concentrates the chlorides into an ever-decreasing volume of water. This makes the solution more corrosive as it evaporates, until salt solids are deposited.

Recommendation for minimising tea staining Here is a list of factors that should be considered when specifying enclosures in areas close to the ocean, or where high levels of chlorides occur naturally, or are found in wash waters. This starts with basic initial material selections, and proceeds into maintenance of the equipment to ensure a long life, and therefore maximum value for the equipment. Material Selection – Initial material selection for the enclosure is of critical importance to the longevity of the equipment. Stainless steel of grade 316 or above should be used as minimum, as lower grades such as 304 are significantly less resistant to chloride attack due to the absence of molybdenum. Surface Finish – The rule of thumb for surface finishes is that the smoother the finish, the better will be the resistance to tea staining. In the absence of any other treatments bright polishing for marine atmospheres is the default recommendation. The brushed surface with maximum surface roughness of 0.5 micron (the Ra defined in EN 10088-2) is a useful alternative where other factors preclude the use of bright polishing. This offers a good level of protection in all but the most severe of cases, at a reasonable cost. Cleaning – Regular washing with clean, fresh water or even rain water has a significant effect on reducing the incidence of tea staining in the environments that can cause concern (see above). Where tea staining still occurs despite regular washing, additional protection can be provided by the BROMOCO Systems coating procedure.

EPC7460A Stainless Steel Protective Coating EPC7460A Stainless Steel Protective Coating has been specifically formulated for coating buildings cladding / and siding, balconies and all other externally exposed architectural structures. This formulation is the hardest wearing of our coatings, though remains flexible enough to withstand the expansions and contractions of the coated surface and is guaranteed not to crack, peel or yellow. The formulation contains higher levels of salt resistance enabling total protection against salt air, salt fog, salt water, bleach, acids and bird droppings. Antioxidant With built in antioxidants the coating is crystal clear and leaves a finish that enhances the natural look of the stainless steel whilst protecting the surface from oxidisation and corrosion. Self-annealing Because of the self-annealing properties of the coating, applying additional coats several years later is a simple process. When an additional coat is applied to a previously cured area, the new coating reacts with the cured coating and forms a bond. . Additionally if the surface becomes scratched or damaged in anyway simply coat the damaged area and create an invisible repair. Self-levelling In cases where the surface of the metal to be coated has been damaged by oxidization or rusting, the cleaned surface may be pitted or rough. The self-levelling properties of the coating will leave a smooth finish, filling the pit mark, therefore not allowing dirt to build up within them. Fully removable (reversible) Unlike epoxies and lacquers the coating is fully removable without damage to the substrate, should any faults occur under the coating due to incorrect preparation of the substrate. Virtually invisible hard wearing protection The application of EPC7460A is virtually invisible at only 5 microns thick on the surface, and enhances the desired natural finish of the surface rather than giving the appearance of a plastic coating, such as lacquers or epoxy coatings. Hardness and scratch resistance
