DENSITY
Rev 2 /Dec 2015 Test specimens were neat epoxy (without fiber reinforcement).
Typical values, not to be construed as specification.
Low viscosity for good wet out of all
synthetic composite fabrics and core
materials.
Slow cure hardener provides approximately
160 minutes of working time at 72 F (22 C). A
typical laminate will gel in about 4 to 5 hours
at 72 F (22 C).
Optimized for 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
g as high as 172 F (78 C) with proper post
cure providing excellent temperature stability
and great part cosmetics.
Cost effective, high performance epoxy
formulation for synthetic composite
manufacturing.
Quality-control tinting is available at no extra
charge; simply add “QC” after the product
code on your order.
Shelf life is 3 years for resin and 2 years for
hardener when properly stored

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.
