Resin system withstand high temperatures

Sika has unveiled a new epoxy resin which boasts great performance in high temperatures.

Various accompanying hardeners have also been introduced all of which offer similar properties but vary in working times, ranging from 60 to 210 minutes. CR132 can be used, for example, in light aviation as the resin can perform in temperatures exceeding 130°C and is therefore capable of withstanding intense solar heat. It is available in the UK from John Burn, which stocks this new resin and its hardeners.

Biresin CR132 resin is a hand laminating base system with three hardeners all of which offer similar properties but have varying pot lives, from 60 to 210 minutes, allowing for efficient production of different size parts.

Based on the properties of the base CR132 epoxy resin and using the building block principle, two further resins have been developed. Biresin CR132 FR with the existing hardener Biresin CH132-2, is a special flame retardant, which can be used, for example, in the production of cowlings and fireproof bulkheads via hand lamination.

With a total of 3 resins and just 4 hardeners Sika offers a complete product family in the form of a modular system, that deliver high performance results in a wide variety of applications in the aviation industry.
