HM-SS2649 silicone weather-resistant adhesive for construction is a kind of one-component, neutral curing, low modulus, high elasticity silicone rubber; it has good elasticity and displacement deformation ability, and has good adhesion to various powder coating metals The thixotropy of the product prevents it from sagging when it is applied in building joints, so it is especially suitable for the design of non-structural bonding, weather resistance, and waterproof sealing of various curtain walls; at the same time, it can be used in a wide range of climate temperatures It can be used, and it has good adhesion and compatibility to the surface of most substrates without primer. After curing, it is anti-aging, anti-ultraviolet radiation and extreme high and low temperature (-50- 150°C) changes; it has Low modulus performance, can bear the expansion and displacement capacity of the interface ± 25%, can be widely used in bonding and sealing.
