Loctite PL Premium Polyurethane Construction Adhesive is a one-component, polyurethane-based, moisture-curing adhesive. It is VOC compliant and contains no chlorinated solvents or water. Loctite PL Premium provides superior adhesion to most common construction materials. It can be used for interior or exterior projects and is three times as strong as conventional solvent-based construction adhesives. It is also waterproof, paintable and cures even in cold temperatures, making it ideal for subfloor installations.
