SS521 is a one-component, neutral curing silicone structural sealant designed for the structural bonding and sealing of glass, aluminum panel curtain walls, glass skylights and metal structural projects. It has excellent structural bonding properties and weathering resistance. After the artificial accelerated weathering test, the physical and chemical properties of the sealant did not change significantly. Use a glue gun to squeeze the glue from the sealant cartridge to the part that needs to be bonded and sealed. The sealant absorbs the moisture in the air at room temperature and solidifies into an elastomer to form a seal.
