In addition to having the advantages of ordinary silicone sealant weather resistance, high and low temperature resistance, strong adhesion, etc., it also adds excellent tensile and compressive properties.;
Excellent high and low temperature performance, after curing at a low temperature of -50°C, it will not become brittle, harden or crack, will not soften or degrade at a high temperature of 200°C, and always maintain good elasticity;
It does not contain solvents, is non-toxic, odorless, odorless, and does not change color after curing, and is non-corrosive to materials such as metals, rubbers, fabrics, organic fabrics, and plastics.;
Excellent weather aging resistance, heat-resistant aging, UV resistance, ozone resistance, and water resistance.
