Gougeon Brothers PRO-SET® LAM-125/LAM-237 Laminating Epoxy
Categories:	Polymer; Thermoset; Epoxy
Material Notes:	Low viscosity for quick wet out of synthetic composite fabrics; especially effective with Kevlar® and carbon fiber. Extra slow cure speed hardener provides 7 to 8 hours of working time at 77°F (25°C). A typical laminate will be gelled in 12 to 14 hours. Optimized for hand wet out and machine impregnation in contact molding, vacuum bagging and Light RTM applications. Room temperature cure properties suitable for many composite components and structures. Tg as high as 198°F (92°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.
