LAM-125 LAM-229 - PRO

LAM-125
LAM-229
LAMINATING EPOXY
COMBINED FEATURES
Low viscosity for quick wet out of synthetic
composite fabrics; especially effective with
Kevlar and carbon fiber.
Slow cure speed hardener provides 4 to 5
hours working time at 77°F (25°C). A typical
laminate will be gelled in 6 to 7 hours.
Optimized for hand wet out and machine
impregnation in contact molding, vacuum
bagging and Light RTM applications.
Room temperature cure properties suitable
for many composite components and
structures.
Tg as high as 197°F (92°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

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.
