RTV106 - (Red) High Temperature Silicone (327gm Cartridge)
GIS28086
Momentive SNAPSIL™ RTV106 – High Temperature Paste Silicone Adhesive Sealant
SNAPSIL™ RTV106 is a one-component, ready-to-use, red paste silicone sealant designed for demanding high-temperature applications. It cures at room temperature upon exposure to atmospheric moisture, forming a durable, flexible silicone rubber that maintains performance under extreme thermal conditions. Designed for vertical and overhead applications, these sealants maintain their shape without sagging, making them ideal for industrial gasketing, bonding, and sealing where aesthetics and performance must align.
The RTV106 is approved to MILSPEC standards, is ideal for defence, aerospace, and other demanding industrial settings that need dependable, standardised silicone sealants.
As acetoxy-cure silicones, they release acetic acid vapours during the curing process.
Key Features
- High-temperature performance: Continuous use up to 260°C (500°F); intermittent exposure up to 315°C (600°F)
