OEM-approved 3M™ Surface Pre-Treatment AC-131 is an excellent option for aircraft surface pretreatment: its water-based and non-chromate formula makes it a great alternative to traditional conversion coatings for aluminum, stainless steel and titanium alloys, and helps reduce process steps such as scrubbing and post-rinsing. It is a solution gelation, or sol-gel, system proven to reduce rivet rash and improve adhesion between the metal surface and the coating system. It applies easily by brush, dip or using 3M™ Accuspray™ and PPS ™, and cures under ambient conditions.
Save time, save water, reduce waste and improve profitability. 3M Surface Pre-Treatment AC-131 requires no scrubbing, no rinsing, and because it is both water-based and non-chromate, it is an environmentally responsible alternative to traditional conversion coatings. This treatment significantly reduces paint loss on rivet heads, protecting against corrosion and keeping your aircraft looking its best. Apply by brushing, dipping or spraying; it cures in ambient conditions, providing excellent wet or dry adhesion with leading aerospace primers and topcoats.
The 3M™ Accuspray™ Spray Gun System with Standard PPS™ combines the simplicity and easy maintenance of our Accuspray™ spray guns and with the material-saving, rapid clean-up convenience of PPS™. Replaceable atomizing heads afford the performance of a new gun, on demand and at a fraction of the cost.
