3M™ Surface Pre-Treatment AC-131

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

Difficult Made Easy
Hazardous waste is detrimental on many levels, including the burden it places on costs. But many of the current surface prep techniques produce significant amounts of hazardous waste. 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. When used with leading aerospace primers and topcoats, 3M AC-131 Surface Pre-Treatment provides equivalent or better wet and dry adhesion performance over many other surface preparation techniques used in both OEM and repair/repaint applications. AC-131 Pre-Treatment is easy to apply either by brush, dip or spray and cures under ambient conditions.

An Environmentally Responsible Alternative
3M™ Surface Pre-Treatment AC-131 offers significant water reduction during use and a total cost reduction compared to conventional processes. And it is both water-based and non-chromated, making 3M AC-131 an environmentally responsible alternative to traditional conversion coatings.
