High Temperature R.T.M. Resin - HTR-386

Category: Laminating
Ratio: 100pbw to 25pbw
Hardener: HT-9234
Description: HTR-386 is a tough, good impact, high temperature resin system that offers excellent heat distortion for parts requiring elevated temperatures. It has excellent handling properties, stable physicals with good flow and we-out for injection resin system. HTR-386 cures at room temperature in 24 hours then must be post cured. Upon completion, the tool should be allowed to cure at ambient temperature. At that point apply an oven cure according to the following schedule: (this schedule is recommended for a tool which will be exposed to an operating temperature of 350°F). 1 hour @ 150°F 1 hour @ 250°F 3 hours @ 350°F 1 hour @ 400°F
