3M™ Surface Pre-Treatment AC-131 is a non-chromated coating for use on aluminum, steel, and titanium alloys. This solution gelation, or sol-gel, system effectively improves adhesion between the metallic surface, and epoxy or polyurethane-based organic coatings. This water-based formula meets high performance aircraft paint application requirements.

3M™ Surface Pre-Treatment AC-131 can help you maintain a competitive edge by reducing hazardous waste and its associated costs while helping to improve adhesion between the metal surface and the coating system. This sol-gel system is proven to significantly reduce rivet rash - the loss of paint on rivet heads that occurs on forward aircraft sections prepped with inferior paint pre-treatment products and applications. Rivet rash increases the risk of corrosion and diminishes the overall appearance of an aircraft.

Suggested Applications

  • Improves adhesion between the metallic surface, and epoxy or and polyurethane-based organic coatings
