This product is a sophisticated, precision-molded sealant with a removable liner on both sides. It features a tight, permanent, and waterproof seal. It also remains flexible in temperatures as low as -57°C (-70°F), making thermal shock that could cause leakage virtually impossible. This product adheres to a wide range of surfaces, including EPDM, TPO, Hypalon, aluminum, galvanized steel, gypsum board, wood, many types of plastic, fiberglass, brick, concrete, masonry, and solar panels |
