Low viscosity for quick wet out of synthetic
composite fabrics; especially effective with
Kevlar and carbon fiber.
Fast cure speed hardener provides 40
minute working time at 77 F (25 C). A typical
laminate will be gelled in about 1.5 to 2 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.
T
g as high as 193 F (90 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.

Medium viscosity for good wet out of all
synthetic composite fabrics and core
materials.
Extended open time hardener provides 8 to
9 hours of working time at 85 F (29 C). A
typical laminate will be gelled in 12 to 14
hours at 85 F (29 C).
Optimized for hand wet out and machine
impregnation in contact molding, vacuum
bagging and filament winding applications.
Elevated temperature cure is required;
thermal and mechanical properties suitable
for composite components and high-
temperature tooling and molds.
T
g as high as 213 F (101 C) with proper post

and great part cosmetics.
Cost effective, high performance epoxy
formulation for synthetic composite

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.

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.

Low viscosity for quick wet out of synthetic
composite fabrics; especially effective with
Kevlar and carbon fiber.
Extra slow cure speed hardener provides 7

typical laminate will be gelled in 12 to 14
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.
T
g as high as 198 F (92 C) with proper post

and great part cosmetics.
Cost effective, high performance epoxy
formulation for synthetic composite

Low viscosity for quick wet out of synthetic
composite fabrics; especially effective with
Kevlar and carbon fiber.
Medium cure speed hardener provides 2 to 3
hours of working time at 77 F (25 C). A typical
laminate will be gelled in 4 to 5 hours.
Optimized for hand wet out and machine
impregnation in contact molding, vacuum
bagging and Light RTM applications.
Room temperature cure properties suitable

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.

Test specimens were neat epoxy (without fiber reinforcement).
Typical values, not to be construed as specification.
VISCOSITY VS TEMPERATURE
Low viscosity for quick wet out of synthetic
composite fabrics; especially effective with
Kevlar and carbon fiber.
Extra slow cure speed hardener provides 7 to
8 hours of working time at 77 F (25 C). A
typical laminate will be gelled in 12 to 14 hours.
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 high temperature
tooling and molds.
Tg as high as 281 F (138 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.

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.

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.
