Product Introduction
BLD-660 is one-component, neutral, room-temperature curing silicone weathering sealant that is easy to use; Excellent weather resistance, long service life, ultraviolet rays, ozone, rain, hail, extreme high and low temperatures will not affect it; Good adhesion, strong adhesion to most building materials after curing; Excellent tensile and compressive properties. The cured sealant retains good elasticity between -40°C and 120°C and is inferred from aging tests: Do not harden or crack under normal climatic conditions.
