Ultraseal’s Greener Solutions To Porosity

Leaders in Recycling Impregnation Technology

Global company Ultraseal is leading the world with its innovative solutions to the eternal problem of porosity in castings – so much so it has changed the face of the impregnation industry. “Manufacturers now regard impregnation as an essential quality enhancement,” said Gary Lloyd, Managing Director of Ultraseal. “It is a world away from its old image as a solution of last resort. “Far from hiding the fact that they impregnate parts, manufacturers are now perfectly open about it: they know it signifies a commitment to quality on their part to their customers.” Few companies can match Ultraseal’s reputation in the field of impregnation – a reputation that has won it an impressive list of global names in the automotive, foundry and manufacturing sectors. Ultraseal’s recyclable sealants Rexeal 100 and Ultraseal MX2 are the only recyclable sealants in widespread application that are approved and certified to US military standard US MIL-I-17653C (Class 1 and 3). Having beaten the world to introduce the first recyclable sealant, Ultraseal’s latest innovation is an impregnation system that is more environmentally-friendly than ever before. Ultraseal has taken recycling to a new level with the introduction of a fully closed-loop, effluent-free impregnation system that can run 24 hours a day without any production line down time to refill and reheat process tanks. As well as a “Sealant Recycling System” connected to the cold wash module, this system incorporates Ultraseal’s latest development, a Water Recycling System, on the hot cure module.

LUBROLENE REVOLUTIONISES DIE-CASTING The revolutionary Lubrolene range of waterfree die release agents can now be applied with an electrostatic spray gun – a world first from the Aoki Science Institute of Japan. This new method of application gives improved coverage on complex parts, exact control of spray quantity, reduced spray and shot cycle times, and all at a reduced cost. Lubrolene oil-based, water-free lubricants already offer cost savings of up to 85 per cent on full production costs of operating a die-cast machine. Ultraseal has the exclusive European distribution rights for Lubrolene. See page 7.

Rexeal 100 – The New Generation of Recylable Sealant Rexeal 100 is a new generation of recyclable sealant that not only offers a greener solution to porosity in castings, but also offers a superior performance when compared to other sealants. Notably, Rexeal 100 can operate at temperatures ranging from -105°F to 428°F (-76°C to 220°C), making it especially suitable for use on parts that are exposed to thermal cycling such as engine castings. Rexeal 100 combines all the successful recycling qualities of methacrylate-based Ultraseal MX2, the world’s first commercially available recycling sealant, with additional advantages. Rexeal 100: • Highest performance recycling sealant on market • Environmentally friendly • Increased cost effectiveness Product

Rexeal 100 Conventional sealant impregnation is wasteful: up to 95% of the sealant is simply flushed away with the wash water. In contrast, Ultraseal’s Sealant Recycling System (SRS) separates Rexeal 100 or Ultraseal MX2 from the wash water and returns it to the autoclave for immediate re-use. Ultraseal’s processes consume less chemicals, less energy and produce less effluent. Rexeal 100

Where 0 = pressure tight (leak free) and 5 = bad leakage The results in this table were generated from tests with a standard batch of competitors’ sealant and Rexeal 100.

Superior Performance of Rexeal vs. Competing Products We consistently monitor our sealants’ performance against others on the market. This guarantees that the statements we make about the quality of our products and their performance are proven correct. The test results show how impregnated US MIL test rings performed when subjected to thermal tests, with any leakage being recorded and graded as shown in the chart.

The results show that even when exposed to relatively low temperatures (40°C), the competitors’ sealant performance is found to suffer after only short periods of time. By comparison, Rexeal 100 retains a perfect ring seal even after 24 hours at 220°C.

Ultraseal‘s Range Of Impregnation Equipment


Hot Cure Cycle

GREENER IMPREGNATION WITH ULTRASEAL’S RECYCLING SYSTEMS

Ultraseal’s latest development is its Water Recycling System for the hot cure stage of the impregnation process. This last piece of the recycling jigsaw allows the whole impregnation process to be practically effluent free.

Ultraseal is already having an impact on the environment – its customers recycle more than 1.25 million litres of sealant a year and the figure is rising.

Without this breakthrough, hot cure tanks have to be periodically drained and cleaned, a process that can take hours because of health and safety regulations, resulting in loss of valuable production time.

They achieve this impressive result by using Ultraseal’s world-beating recyclable sealants in its innovative Sealant Recycling System (SRS) attached to the cold wash module.

The Water Recycling System works by continuously pumping water from the hot cure tank to an energyefficient distillation unit where the water is purified before being returned to the hot cure tank for re-use.

The SRS takes the wash water from the cold wash module after impregnation and separates the sealant from the water, redirecting to the autoclave for immediate re-use. Up to 95 per cent of the sealant can be recovered.

Only a tiny amount of concentrated waste is produced during the distillation process – less than one per cent of the volume of water in the tank. During distillation it is separated from the water and collected automatically for disposal.

This is in stark contrast to traditional impregnation systems, in which most of the sealant simply drains away with the wash water, and wash tanks are typically allowed to overflow continuously.

The Water Recycling System offers several cost savings:

The SRS is designed for use with Ultraseal’s methacrylatebased recyclable sealants Rexeal 100 and Ultraseal MX2 which are both approved and certified to US Military specification US MIL-I-17563C (Class 1 and 3).

• Less water used • Less energy required to heat water • Lower bills for effluent disposal • No production down-time

Now Ultraseal has taken recycling to the next level with the development of a totally closed loop, effluent free impregnation system that incorporates both the SRS on the cold wash module and it latest innovation, effluent free technology on the hot cure cycle.

Moreover, the combination of a Water Recycling System on the hot cure module and a Sealant Recycling System on the cold wash module creates a totally closed loop, effluent free impregnation system – for the first time. “Certain chemicals that

Ultraseal International Produces The Only U.S. Military Approved Recyclable Sealants In Widespread Application Rexeal 100 approved for US MIL-I-17563C (Class 1 and 3) “Moreover, by recycling both the sealant and water, our recyclable systems are kinder to the environment and less expensive than conventional processes in which 95% of the chemical and water is simply washed away.” The truly recyclable nature of the process was on show at the 12th International Foundry Trade Fair GIFA 2011. Importance of Approvals

Rexeal 100 and MX2 are officially approved for US military specification MIL-I-17563C (Class 1 and 3) and are the only recyclable sealants being used widely in industrial and automotive applications. This US Mil standard is widely accepted throughout the world as the global benchmark for impregnation sealant performance. Rexeal 100 is the flagship product of Ultraseal, the UKbased company with a global presence that introduced the world’s first recyclable sealant, Ultraseal MX2. Both sealants are designed as solutions to the eternal problem of porosity in castings and both are approved for MIL-I-17563C (Class 1 and 3). Rexeal 100 is a refinement of Ultraseal MX2 and operates across a wider temperature range: -76°C (-105°F) to +220°C (428°F). Gary Lloyd, Managing Director of Ultraseal, said: “Ultraseal has always been at the forefront of impregnation technology that reliably and permanently solves porosity in castings. “We are delighted that both Rexeal 100 and Ultraseal MX2 are approved and certified to the US MIL-I-17563C (Class 1 and 3), demonstrating to our customers that our products are robust and reliable. “This standard is widely accepted throughout the world and Ultraseal produces the only U.S. military approved recyclable sealants used in widespread industrial and automotive applications. In fact, no other European manufacturer has this approval for recycling impregnation sealants.

Ultraseal is proud to have been awarded a large number of International Approvals that reflect the global acceptance and application of its products and which give current and future customers the confidence to specify Ultraseal products in their impregnation applications. Examples of Ultraseal’s wide range of International Approvals include: • Water • Electrical • Gas • US Military • Underwriter’s Lab • International Test Standards Electroseal 35 Electroseal 35 is a sealant specifically formulated for use in electrical leads and connectors, especially those used in the automotive industry, that need protection against ingress of moisture and contaminants. Flexible in the cured state, it is also hydrophobic, has a low di-electric constant, and a low cure temperature to protect against possible thermal damage. It is also resilient to shock and vibration when in use. Sinterseal 100 Sinterseal offers manufacturing savings to companies producing parts with powdered metal finishes. Specifically formulated for this particular use, Sinterseal greatly reduces the wear and tear on machine tools, leading to reduced production running costs.


Lubrolene Water-Free Die Cast Lubricants Produce Higher Quality Castings at Greatly Reduced Costs Ultraseal is joining forces with the Aoki Science Institute to promote one of the most exciting developments in the die-casting industry – the range of Lubrolene water-free die lubricants. Lubrolene is set to transform the efficiency of the die-casting industry with its range of oil-based lubricants that offer dramatic cost savings when compared with conventional waterbased die lubricants. Impressive savings of up to 85 per cent on the costs of operating die cast machines can typically be achieved if Lubrolene lubricants are used instead of water-based die releases.

The faster spray times and reduced air-blow substantially decrease cycle times. There is far less thermal shock on the die, leading to longer die life, reduced maintenance costs and better quality castings. Water-based lubricants give rise to continual heating and cooling cycles that produce considerable thermal shock on the die that eventually leads to cracking. The water can often also cause porosity in the casting leading to quality problems. Using Lubrolene water-free lubricants

A revolutionary new step in die casting has been taken with Lubrolene’s WFR-EC oil based series which is suitable for electrostatic spray application, a world first and a step change in technology. The electrostatic spray essentially has Product Die temperature
