Create a Strong, Secure Seal
3M™ Black Super Silicone Seal exhibits excellent resistance to vibration, moisture, ozone and extreme temperatures. Our sealer is a paste-like, one-component material that cures to a tough, rubbery solid when exposed to moisture in the air. This silicone seal comes in a tube for easy dispensing and application convenience.
Exceptional Resistance to Real-Life Conditions
Our silicone seal delivers toughness and durability when exposed to common environmental effects. It exhibits high temperature resistance, good weathering resistance and good water resistance.
Performance Properties
This sealer will dry tack free in 15 to 20 minutes and has a cure-thru time (1/8 inch thickness) in 24 hours.
