DT-687
Description
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.
