Reliable paste-like gasket sealant/dressing/coating. Gasket sealants can provide up to 95% material savings over hard gaskets while offering flexibility in design, allowing for lower cost manufacturing methods. Gasket sealants are used to prevent leakage of fluids or gases by forming impervious barriers. They cure in the presence of metal and the absence of air to form a durable seal between components. Gasket sealants also eliminate corrosion and provide an instant, low-pressure seal on an assembly after full cure. Gasket sealants will not shrink, crack or relax, and resist displacement better than conventional gaskets.
