Seal Bond 500 High Strength Adhesive Sealant

SB 500 is an extremely high-strength, one-component, adhesive & sealant for solar, roofing and construction. SB 500 is a low odor and 100% solids formula designed for interior and exterior construction applications. SB 500 is an environmentally friendly formula that contains no solvents or isocyanates and yields very low VOC’s. SB 500 is based on moisture cure hybrid polymer technology that reacts and cross-links in the presence of moisture to provide a durable seal with excellent weathering and UV resistance and performs in temperatures from -40o F to 200o F.

NOTE: You will need a Heavy Duty Manual Caulking Gun for this sealant, we recommend;   Albion B26, COX 41004-XT, or ATC #TM9HD
