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.
