High-temperature, high-performance epoxy
surface coat formulation for synthetic composite
parts and tooling manufacturing. Black in color.
T
gas high as 270 F (132 C) with proper post-
cure. Provides excellent temperature stability and
great part cosmetics.
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
thickness of 10-12 mils.
Elevated temperature cure is required. The
surface coat and laminate should be post cured
together. See chart for post cure information.

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).

High-temperature, high-performance epoxy
surface coat formulation for synthetic composite
parts and tooling manufacturing. Black in color.
T
gas high as 270 F (132 C) with proper post-
cure. Provides excellent temperature stability and
great part cosmetics.
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
thickness of 10-12 mils.
Elevated temperature cure is required. The
surface coat and laminate should be post cured
together. See chart for post cure information.

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).

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 or hardener to crystallize. If this occurs, warm the resin or hardener 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.
