Henkel Corp. has introduced a new, water-based reactive autodeposition coating formulated specifically to deliver a uniform, defect-free surface coating on raw cast components and ferrous metals. This epoxy-acrylic urethane coating easily coats both the inside and outside of complex components, and delivers enhanced corrosion and abrasion resistance, excellent thermal stability, and superior edge protection, abrasion resistance, and flexibility.

Depending on the type of substrate and cleanliness of the metal, application of the coating can be as simple as a seven-step, room-temperature deposition process that requires no electrical contacts and involves a chemical reaction between the water-based organic emulsion and the metallic surface. The low-energy process uniformly coats large volumes of fully assembled, densely racked or complex-shaped metal parts and involves some combination of the following steps: cleaning, rinsing, coating, sealing and curing. From beginning to end, preparation and application usually takes significantly less time than competing processes.

The new coating, Bonderite®M-PP 930C, will coat any surface it wets during immersion of the parts with no limitation as to part size, shape, complexity or density. The coating covers the entire inner diameter of cylindrical parts, controlling warranty exposure. The non-flammable, non-explosive, RoHS-compliant coating contains no toxic heavy metals, very low VOCs, and no APEs or HAPs. The technology is an excellent coating for general industrial, heavy equipment, agricultural and construction equipment, trucks, trailers, and automotive applications.
