Ensures professional results on every application with consistent performance you can count on.Multi-Surface Adhesion Bonds exceptionally to metal (steel, aluminum, cast iron, stainless steel, brass, copper), glass, wood, ceramic, vulcanized rubber, most plastics, painted surfaces, and natural/synthetic fibers. One product for countless applications.Superior Chemical Resistance Excellent resistance to motor oils, gear oils, hydraulic fluids, coolants (ethylene glycol, propylene glycol), transmission fluids (ATF, CVT), and water (freshwater and saltwater). Maintains seal integrity in harsh automotive and industrial environments.Exceptional Flexibility High elongation properties allow the gasket to stretch and compress through thermal cycling and vibration without cracking or losing seal integrity. Perfect for dynamic applications where components expand and contract with temperature changes.Excellent Electrical Insulation High dielectric strength and volume resistivity make BroGasket ideal for electrical motor housings, control boxes, junction boxes, and applications requiring both sealing and electrical isolation. Prevents current leakage and short circuits.Custom Color Mixing Mix different colors to create custom hues that match your specific application requirements or aesthetic preferences. Endless color possibilities for professional finishing touches.Extended Shelf Life Self-sealing nozzle technology prevents premature curing and product waste. Maintains freshness for 12-18 months after opening versus only 3-6 months for conventional tubes. Always ready when you need it.Fast Working Time Develops initial tack in just 10 minutes to hold parts in position. Reaches functional cure in 24 hours for most applications. Full cure and maximum strength achieved in 7 days.
