Applications
S920 is a high temperature resistant silicone sealant, which is single component and moisture curing. It has excellent heat resistance after curing, maintaining elasticity and adhesion at high temperature. It can be used for a long time at -50℃~250℃.
Advantage
✅Neutral curing, no corrosion for base materials.
✅High elastic strength and high elastic modulus.
✅Anti-UV, heat aging resistant, suitable for outdoor and indoor.
