Gougeon Brothers PRO-SET® LAM-125/LAM-239 Laminating Epoxy
Categories:	Polymer; Thermoset; Epoxy
Material Notes:	Medium viscosity for good wet out of all synthetic composite fabrics and core materials. Extended open time hardener provides 8 to 9 hours of working time at 85°F (29°C). A typical laminate will be gelled in 12 to 14 hours at 85°F (29°C). Optimized for hand wet out and machine impregnation in contact molding, vacuum bagging and filament winding applications. Elevated temperature cure is required; thermal and mechanical properties suitable for composite components and high-temperature tooling and molds. Tg as high as 213°F (101°C) with proper post cure providing excellent temperature stability and great part cosmetics. Cost effective, high performance epoxy formulation for synthetic composite manufacturing. Quality-control tinting is available at no extra charge; simply add "QC" after the product code on your order. Information provided by Gougeon Brothers, Inc.
