STANDARD HIGH-TEMP SYSTEMS

PRO-SET High-Temperature Epoxies are a system of high-performance epoxies for synthetic composite mold and part manufacture. The High-Temperature system consists of a Surface Coat Epoxy, Laminating Epoxy and an Infusion Epoxy. When combined to manufacture composite parts, they can be demolded after 24-48 hours at room temperature before a freestanding postcure.

The Tg of this system is as high as 300°F (149°C) with proper post cure. It has excellent temperature stability and part cosmetics.

The Infusion and Laminating Epoxies can be dyed, upon request, to provide for visual quality control. A yellow dye in the resin and a blue dye in the hardener, when properly metered and thoroughly mixed, will result in a consistent shade of green. The Surface Coat Epoxy is available only in black.

*Application Tips for HTP 187-287 High-Temp Surface Coat only
  • 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 to a thickness of 10-12 mils.
  • Let surface coat cure between each application and prior to lamination. Wash with water and a Scotch Brite Pad to remove amine blush. IMPORTANT! Blush may not be visible and can occur while product is still tacky.
  • 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.
