High-temperature, high-performance epoxy
formulation for synthetic composite part and tooling
manufacture.
T
g
as high as 300 F (149 C) with proper post cure.
Provides excellent temperature stability and great part
cosmetics.
Fast cure speed hardener provides 1 to 2 hour
working time at 72 F (22 C). A typical laminate will
gel in 4 to 6 hours at room temperature.
Medium viscosity for wet out of synthetic composite
fabrics.
Elevated temperature cure is required. Parts can
be pulled after 24-48 hours at room temperature or
sooner after a mild initial cure of 90-110 F (32-43 C).
See chart for post cure information.

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 CO
2
and moisture in the atmosphere for extended periods of time. Prevent
carbamation by protecting hardeners from exposure until immediately prior to processing.
