S920
High-temperature silicone sealant
S920 is a high-temperature silicone sealant, single-component, moisture-curing. After curing, it has excellent heat resistance, maintaining elasticity and adhesion at high temperatures, and can be used for a long time at -50℃~250℃.
Advantage
• Neutral curing - safe for most substrates
• Exceptional elasticity with high modulus
• UV stable and heat aging resistant
• Dual-purpose for interior/exterior use
