Description
Crystal-clear flowing epoxy for stone lamination and flat seams. Tenax StrongEdge Express is a two-part transparent flowing epoxy engineered specifically for stone fabrication — laminating countertop edges, bonding flat seams, and structural applications where the adhesive needs to self-level and flow into the joint for full coverage. Recognized as one of the clearest epoxies on the market, StrongEdge Express maintains superior transparency throughout its service life with no yellowing.
Non-shrinking formula polishes to a high-gloss finish and accepts color paste for precise stone matching. 40-minute set time at 75°F. 2:1 mix ratio. VOC compliant. Suitable for indoor and outdoor use on all stone types, ceramic, and porcelain.
