Features: Extended open time hardener provides 8 to 9 hours of working time at 85°F (259°C). A typical laminate will be gelled in 12 to 14 hours at 85°F (259°C).

Optimized for hand wet out and machine impregnation in contact molding, vacuum bagging and Light RTM applications.

Elevated temperature cure is required; thermal and mechanical properties suitable for composite components and hightemperature tooling and molds.

Tg as high as 215°F (102°C) with proper post cure providing excellent temperature stability and great part cosmetics.

Cost effective, high performance epoxy formulation for synthetic composite manufacturing.

³ - Store PRO-SET® Epoxy resins and hardeners at room temperature in sealed containers until shortly before use. As with many high-performance epoxy resins, repeated exposure to low temperatures during storage may cause the resin to crystallize. If this occurs, warm the resin to 125° F and stir to dissolve crystals. Hardeners may form carbamation when exposed to CO2 and moisture in the atmosphere for extended periods of time. Prevent carbamation by protecting hardeners from exposure until immediately prior to processing.
