Recycling Sealant

Recycling Technology
While conventional sealing technologies have made major advances in terms of quality and consistency, increasing concerns over the efficiencies and effluent impact of the process has led to increased research towards a more friendly and effective solution.

In traditional impregnation processes, up to 90% of the sealant consumed goes down the drain as effluent from the cold water wash tank. This is not only wasteful and adds cost to the process, but also brings a greater financial burden to bear on companies that are facing ever-increasing environmental legislation and concerns. The growing need for manufacturers to reduce bottom-line costs and address environmental issues led Ultraseal International to develop the world’s first recycling sealant in 1987. This revolutionary sealant, offered all the qualities of conventional sealant but with the added commercial and environmental advantages of being recyclable.

Instead of being simply washed down the drain and wasted, the sealant is collected from the wash tank and passed through the Ultraseal Sealant Recovery System (SRS) for retrieval and reuse.

With sealant consumption reduced by up to 90% and water usage also significantly cut, users have been quick to see the benefits – particularly as zero effluent is produced from the cold wash tank, creating an associated reduction in treatment costs.

Ultraseal MX2
MX2 was the world first commercially available recycling sealant and even today remains as the only recycling sealant to have been in use throughout the world for almost two decades. Its versatility and reliability is illustrated by the number of international users and the variety of applications for which it is employed.
Rigorous laboratory testing ensured that Ultraseal MX2 delivered the same results as Ultraseal PC504/66 and is also approved to the internationally accepted US Military Specification MIL – I – 17563C

Ultraseal MX2 sealant has become the preferred choice for companies through a wide range of sectors seeking to maintain sealing quality and consistency while simultaneously reducing sealant and water usage. Expenditure on dealing with the environmental impact of disposing of used sealant is also eliminated.

Characteristics of MX2

A New Generation – Rexeal 100

Despite MX2 being the only world class recycling sealant, Ultraseal has not relaxed from their vision of continuous improvement.

Extensive research by the Ultraseal expert team of chemists has drawn upon a proven track record of more than a decade in the use of recycling sealants to develop this evolutionary product. By examination of the performance of Ultraseal MX2 in the field and taking into account extensive feedback from the market, Rexeal 100 has been specifically formulated to bring additional tangible benefits to the user. It breaks new ground in this field, exceeding current customer expectations. It has been developed specifically to meet the ongoing needs to companies requiring the highest possible levels of sealing quality.

Rexeal 100 is fully compatible with Ultraseal MX2 under normal circumstances and can, if required, be introduced into existing recycling systems.

Benefits of Rexeal 100:

Temperature Testing

Rexeal 100 has been fully tested to stringent international standards, including the Japanese standard Heat/Freeze cycle, a test that challenges the sealant over extremes of temperature.

Thermal Cycling

Aluminium test rings were impregnated with Rexeal 100 and then subjected to temperature cycling at one hour intervals from -76°C to ambient to +160°C to ambient. After 30 days the rings were tested for leaks at 20 bar and remained sealed.

Heat Resistance (Long Term)

Aluminium test rings were impregnated with Rexeal 100 and then subjected to a temperature of 200°C for 30 days. After this period the rings were tested for leaks at 4 bar and remained sealed.
