Gougeon Brothers PRO-SET® HTP 187/HTP 288 High-Temp Surface Coat Epoxy
Categories: Polymer; Thermoset; Epoxy

Material Notes: High-temperature, high-performance epoxy surface coat formulation for synthetic composite parts and tooling manufacturing. Black in color.
Tg as high as 270°F (132°C) with proper post-cure. Provides excellent temperature stability and great part cosmetics.
Slow cure speed provides 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.
Thixotroped to 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.
