DuraSil is a highly flexible silicone adhesive/sealant/caulk designed for 50% joint movement that can handle very low to high temperature extremes. It bonds to difficult surfaces quickly.

This product contains no biocides or fungicides. It is ultra-low odor when wet and no odor once cured. The white will turn slightly off-white over time. The translucent is not clear, but a cloudy color.
Use rubbing alcohol to smooth. Do not use water or mineral spirits or products with xylene.
Alert: Do not use mineral spirits or xylene with DuraSil. Staining may occur on limestone or porous substrates. Do not use on surfaces to be painted or on fire-retardant lumber. High temperatures will reduce shelf life.
