Gougeon Brothers PRO-SET® LAM-145/LAM-226 Laminating Epoxy
Categories: Polymer; Thermoset; Epoxy
Material Notes: Medium viscosity for good wet out of all synthetic composite fabrics and core materials.
Thixotropic 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.
Medium cure speed hardener provides 2 to 3 hours of working time at 77°F (25°C). A typical laminate will be gelled in 4 to 5 hours.
Optimized for hand wet out and machine impregnation in contact molding, vacuum bagging and filament winding applications.
Room temperature cure properties suitable for many composite components and structures.
Tg as high as 219°F (104°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 produce code on your order.
