BOSS® 315 RTV Silicone is a one-component, 100% RTV adhesive/sealant with a paste-like consistency that cures upon exposure to moisture in the air, forming a tough and flexible rubber. Its non-sagging formula allows for overhead and vertical applications without slumping or running.
Excellent resistance to weather, moisture, ozone, and vibration.
Remains flexible over a wide temperature range: -40°F to +400°F (-40°C to +204°C).
Can be applied even in sub-zero conditions without loss of performance.
Strong adhesion to metals, glass, ceramics, wood, vulcanized rubber, and many plastics.
Provides electrical insulation and complies with international standards (ASTM C920, NSF 51, UL).
Sealing oven doors, flues, and gas appliances.
Automotive and trailer sealing – trims, cabs, and bodywork.
HVAC ductwork, sheet metal stacks, and equipment housings.
Marine cabins and window sealing.
Bonding gaskets in heating and refrigeration systems.
