Loctite® PL® Marine Fast Cure Adhesive Sealant is a fast setting, moisture cure polyether adhesive sealant which delivers strong bonds while forming a watertight, flexible seal above or below the waterline once cured. Free of solvents, phthalates and isocyanates, it will not shrink when cured, discolor from UV exposure, or bubble on damp surfaces. Once cured, it withstands both saltwater and freshwater environments.
