PAC33 4355/3600 43553600-KAHA / PRIMER 5LT

PAC33 4355/3600 43553600-KAHA is a two-component aerospace primer engineered to deliver long-term corrosion inhibition and strong intercoat adhesion on aluminum, titanium, and treated steel surfaces commonly found in aircraft structures. Its balanced resin and catalyst system supports uniform film build, rapid curing, and resistance to humidity, hydraulic fluids, and temperature variations, making it ideal for OEM production and MRO repainting. Optimized for use beneath polyurethane or epoxy topcoats, it promotes coating durability in exterior and interior environments, from fuselage panels to landing gear components. Supplied in a 5-liter format, it ensures consistent application on large surface areas.
