High Temperature Epoxy Resins

High glass transition epoxy resins are the essential choice for high temperature applications. Optimax® 8154 fibre optic two-component epoxy has excellent high temperature resistance together with high tensile strength and minimal shrinkage. Ideal for use in medical, optical and semiconductor industries, it has resistance to a wide range of chemicals and solvents. The ability to bond dissimilar materials correctly enables the manufacture of optical components impossible to make with mechanical fastenings. Our Optimax® grade has been engineered for high performance and reliability resulting in lower costs and greater productivity.

Optimax® 8155 is an extreme, constant high temperature epoxy resin used for multiple manufacturing applications. This product offers superior high temperature stability up to 300°C.
