Key Polymer

Tough-Seal 22 A is a tough and durable two component, hybrid epoxy elastomer that features a longer gel time than Tough-Seal 21. Tough-Seal is a superior electrical potting compound with excellent thermal cycling performance.

Tough-Seal 21 A is a tough and durable two component, fast gelling, hybrid epoxy elastomer electrical potting compound with excellent thermal cycling performance. KEY Tough-Sealhas the flexibility of a urethane and the service temperature of an epoxy.

Tough-Seal 42 A is a flame retardant version of Tough-Seal 22. The self-extinguishing flame retardant performance meets UL 94V-0 requirements and has been validated by UL for the official rating. KEY Tough-Seal 42A/Bachieves flame retardant properties without antimony or halogenatedcompounds. Like Tough-Seal, it is a tough and durable two component, hybrid epoxy elastomer that features excellent thermal cycling and exceptional flexibility.

Tough-Seal 41 A is a flame retardant version of Tough-Seal 21. Self-extinguishing flame retardant performance has been validated by UL and KEY Tough-Seal 41A/Bhas achieved a UL94V-0 rating. KEY Tough-Seal 41A/Bachieves flame retardant properties without antimony and brominated compounds.

Tough-Seal 31 A is a tough and durable two component, hybrid epoxy elastomer that features a lower viscosity than Tough-Seal 21.
