StrongEdge 45 Knife Grade

StrongEdge 45 Knife Grade, the strongest clear, Knife Grade epoxy specifically designed for fabrication and lamination. Once applied on a countertop, the stone or substrate will not delaminate or break where it has been applied! Strong Edge 45 is the clearest flowing epoxy on the market. StrongEdge 45 does not shrink, it takes a polish, as well as accepts color to color match the stone if necessary. With a 2:1 mix ratio and a set time of about 45 minutes at 75 degrees.

StrongEdge 45 is made for granite, marble, all-natural stone, Quartz, Engineered, ceramic, and porcelain materials. It maintains the clearest epoxy with an express cure time, without losing its structural integrity.

StrongEdge 45 is truly a knife-grade consistency and is VOC compliant. After mixing the part A and B together, the Strongedge 45 can be used on 45-degree miter and vertical applications without running or dripping off.

Instructions for use

Make sure the surface to be treated is dry, clean, and free of dust. The mixing ratio of resin to catalyst is 2:1 (see chart below). Use clean tools. Stir vigorously and apply. Do not place unused products back in the can. Make sure the cans are sealed tightly after use. To clean tools we suggest light solvents like acetone and butyl acetate.
