Low viscosity for quick wet out of synthetic
composite fabrics; especially effective with Kevlar
and carbon fiber.
Medium speed hardenerprovides up to 150 minutes
of pot life at 72 F (22 C).
Fire retardant system contains high levels of
phosphorous to reduce flame spread and smoke
generation in a composite laminate when compared
to a standard resin system.
Optimizedfor hand wet out and machine
impregnation in contact molding, vacuum bagging and
filament winding applications.
Room temperature cure properties suitable for many
composite components and structures.
T
gas high as 138 F (59 C) with proper post cure
providing excellent temperature stability and great part
cosmetics.

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.
