High Elasticity Sealant For High- Rise Building Curtain wall

High elasticity enables it to absorb thermal expansion and contraction, resisting deformation effectively. No primer is needed, saving construction labor and time. It bonds firmly with glass, aluminum alloy, stone and other substrates, with excellent waterproof and airtight performance, enhancing building energy efficiency. It maintains stable performance in extreme high and low temperatures, non-sagging, suitable for vertical and overhead construction. Smooth extrusion and fast skin-drying shorten the construction cycle, improving efficiency. Low shrinkage after curing avoids cracks and hollowing, with high tensile and tear strength, balanced hardness and flexibility.
