DeBond MF5U Marine Formula Adhesive & Sealant Remover 5 oz Aerosol

DeBond Marine Formula MF5U is an industrial-strength adhesive and sealant remover specifically formulated for the marine industry. This patented blend of solvents and surfactants effectively breaks down and removes cured polyurethane adhesives, including the notoriously tough 3M 5200, making it an essential tool for boat maintenance and repair.

Key Features:

• Removes cured 3M 5200, 4200, 4000, and other polyurethane adhesives and polysulfide sealants
• Effectively dissolves Liquid Nails, masking tape residue, shrink wrap tape adhesive, and duct tape residue
• Cleans black rub marks, graffiti, and overspray
• Works as a cleanup solvent during adhesive application to remove squeeze-out and spills
• Safe on gelcoat, fiberglass, clearcoat, two-part paint systems, and Plexiglass
• 5 oz aerosol can for controlled, precise application

How It Works:

Marine Formula penetrates polyurethane adhesives and breaks down the interlocking molecular chains that form the bond. Small hardware removal may take 2-30 minutes, while larger projects may require multiple applications. For best results, use at temperatures above 70°F and work in shade to slow solvent evaporation. Score around edges with a razor knife to increase solvent access.

Important Safety Notes:

• Do NOT use on plastics (safe on acrylic/Plexiglass only)
• Avoid use on soft paints or varnish
• Keep denatured alcohol or soap and water on hand to stop the chemical process if needed
• Classified as ORMD - ground shipping to contiguous US only
