Standard Epoxies

High Temp Epoxies

PRO-SET High-Temperature Epoxies are a system of high-performance epoxies for synthetic composite mould and part manufacture.

The PRO-SET High-Temperature system consists of a Surface Coat Epoxy, Laminating Epoxy and an Infusion Epoxy. When combined to manufacture composite parts, they can be demoulded after 24-48 hours at room temperature before a free-standing postcure.

The Tg of this system is as high as 149°C with a proper postcure. It has low shrinkage, excellent temperature stability and part cosmetics.

*Application Tips for HTP 187-287 High-Temp Surface Coat only

    • Always evaluate mould 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 moulds, 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.
