PRO-SET Tooling Epoxies are 2-part products formulated for surfacing molds and plugs. The state-of-the-art chemistry behind these epoxies makes them easy to use, saving on labor and yielding high-quality results. They blend quickly, spread easily and shrink minimally.

PRO-SET High-Temperature Epoxies are a system of high-performance epoxies consisting of Surface Coat Epoxy, Laminating Epoxy, and an Infusion Epoxy. When combined to manufacture composite molds, 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.

PRO-SET TLG-625 Low-Density Fairing Putty is formulated for filling and fairing composite structures in manufacturing and repair applications. It can be applied in thicknesses up to ½” (12 mm) without slumping or sagging. The shear thinning characteristic provides excellent featheredge application. The cured putty is very easy to sand and the filler blend minimizes airborne dust during sanding.
