It is a kind of fast acetic curing( based on polysiloxane), anti-fungi silicone sealant, which cures with atmospheric moisture to foam a high strength rubber seal with excellent adhesion to many surface such as glass, glazed surfaces, metals, most plastics, tiles, wood, concrete etc. GORVIA silicone sealant has excellent physical properties that are designed to provide outstanding durability and excellent UV resistant and weather resistant performance, multi-purpose and ready-to-use.
GS-Series N302R is a Neutral Cure GS-Series N302R (non-acid, based on polysiloxane), single component silicone sealant with High tensile strength, high modulus, it is sag resistant and rainwater accessories and will not corrode zinc or zinc/aluminum galvanized steel. It has excellent physical properties that are designed to provide outstanding durability and excellent UV resistant and weather resistant performance, multi-purpose and ready-to-use.
It is based on moisture curing polyurethane, containing safety propellant, is used to seal gaps and crevices with very high expansion yield UP TO 65 LITERS, the post-expansion is quite low to prevent deformation. The foam that dispenses from aerosol can is moisture cured and draws humidity from the air for pipes, windows and doorframes. Foam can be cut once fully cured, provides excellent bond to lumber, plywood, concrete, metals, masonry and other substrates.
