Sashco Lexel, 10.5-Ounce Cartridge, Clear
Lexel is a co-polymer rubber-based sealant. It has excellent adhesion to a wide variety of materials, even after seven days of water immersion.  Although it's tougher and resists tearing, Lexel is a soft rubber. This allows it to stretch and compress with joint movement. Lexel should not be used in areas of continuous submersion (i.e., aquariums or swimming pools). Do not use Lexel in areas where temperatures exceed 200 Degrees F. Lexel may damage some plastics, such as polystyrene foam insulation. Plastics not listed should be tested for Lexel compatibility before general application.
