Product Description
PC-3™
Smooth-On PC-3™ Laboratory Table Top Cement is a two-component, black epoxy resin compound designed to join, bond and caulk sections of laboratory counters and tables. This epoxy resin cement is heavily filled and will adhere to vertical surfaces without sagging. It cures at room temperature with extremely low shrinkage.
Super Instant™
Smooth-On Super Instant™ Epoxy is a two component, clear amber adhesive designed to provide rapid bonding. When mixed in equal proportions—either by volume or by weight—curing takes place quickly enough to permit handling in 5 to 10 minutes at room temperature. Super Instant™ adheres to metals such as steel, aluminum and brass, to wood, glass, masonry and many hard plastics.
