PT2846 is an amber, unfilled high temperature epoxy laminating resin designed specifically for demanding high performance composite tooling. PT2846 has good heat resistance, making it capable of providing excellent long term service in today's higher temperature curing cycles. The resin has a medium-low viscosity, and, when combined with the hardeners recommended here, allows very easy handling in tool fabrication. The mixed systems wet out the tooling fabrics very readily. This allows faster tool production than when using more viscous materials. This feature is achieved without the use of hazardous or potentially restricted diluents. PT2846 does not contain vinylcyclohexane diepoxide (VCHD).
