Gougeon Brothers PRO-SET® LAM-145-BK/LAM-239 Laminating Epoxy
Categories: Polymer; Thermoset; Epoxy
Material Notes: Black Pigmented Resin for a deep black color.
Medium viscosity for good wet out of all synthetic composite fabrics and core materials.
Thixotroped to prevent drain out in heavy fabrics and on vertical surfaces.
High tack to help hold heavy fabric and core in place on vertical surfaces.
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 215°F (102°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.
