Very low viscosity for rapid saturation of
fiberglass, Kevlar and carbon fiber laminate
with resin infusion and VARTM processes.
Fast cure speed hardener provides
approximately 75 to 90 minutes of working
time at 77 F (25 C). A typical laminate will be
gelled in 2 to 3 hours.
This combination is formulated specifically
for resin infusion and VARTM processes. Do
not use in open mold applications.
Room temperature cure properties suitable
for many composite components and
structures.
T
g 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
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.

Very low viscosity for rapid saturation of
fiberglass, Kevlar and carbon fiber laminate
with resin infusion and VARTM processes.
Medium cure speed hardener provides 3 to 4
hours working time at 77 F (25 C). A typical
laminate will be gelled in 8 hours.
This combination is formulated specifically
for resin infusion and VARTM processes. Do
not use in open mold applications.
Room temperature cure properties suitable
for many composite components and
structures.
Tg as high as 196 F (91 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

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.

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 rapid saturation of
fiberglass, Kevlar and carbon fiber laminate
with resin infusion and VARTM processes.
Extra slow cure speed hardener provides up
to 12 hours of working time at 77 F (25 C). A
typical laminate will be gelled in about 16 to
20 hours at this temperature.
This combination is formulated specifically
for resin infusion and VARTM processes. Do
not use in open mold 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 277 F (136 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, 18 months for
hardener when properly stored

VISCOSITY VS TEMPERATURE
COMBINED FEATURES
Very low viscosity for rapid saturation of
fiberglass, Kevlar and carbon fiber laminate
with resin infusion and VARTM processes.
Extra slow cure speed hardener provides up
to 10 hours of working time at 77 F (25 C). A
typical laminate will be gelled in approximately
14 to 18 hours at this temperature.
This combination is formulated specifically
for resin infusion and VARTM processes. Do
not use in open mold applications.
Room temperature cure properties suitable
for many composite components and
structures.
T
g as high as 193 F (89 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.

Slow cure speedprovides 2 to 3 hours working
time at 72 F (22 C). A second application can be
applied while the first coat is tacky, which is
typically after 6-8 hours. After 24 hours cure at
72 F (22 C) the laminating process can begin.
Medium Viscosity enables brush application and
air release. Easily applied with a short bristle
brush.
Thixotropedto prevent runs and sags at a

APPLICATION TIPS
Stir resin before use; some settling may occur.
Always evaluate mold release on a test panel that is characterized with your post-cure schedule.
Apply product using stiff bristle brush. Cut bristles to half of their original length to increase brush stiffness.
When applying, brush in an alternating pattern of 0 and 90 degrees, building to a thickness of 10-12 mils. A total of 20-24 mils of surface coat is recommended before laminating.
Allow surface coat to cure prior to lamination. Wash with water and a Scotch-Brite pad to remove amine blush.
To repair finished molds, grind away damaged surface coat and grind a vee into any cracks. Sand areas with 80-grit sandpaper and fill with surface coat. Post-cure as required. 1 mixed gallon of HTP-187/HTP-288 covers approximately 60 sq. ft. with a final thickness of 24 mils (2 applications).
