Autodeposition Coatings

Revolutionary Auto-Deposition Coating for the Best Protection of Complex Steel Components

Autodeposition is the process of applying a resin/pigment-based coating on a steel surface without the use of a pretreatment/electrodeposition process or a pretreatment/electrostatic application system used in today’s industry. Henkel’s BONDERITE^® M-PP autophoretic coating process applies this resin/pigment-based coating through a chemical reaction with the steel surface and not the pretreatment and electrical requirements required by the other applications.

Without the pretreatment/electrical requirements, the application equipment for the autophoretic coating process reduces the overall initial installation costs, operational costs, reduced maintenance cost, ease of control all while increasing a company’s profitability. Another unique feature of the process is that the coating is deposited only on steel surfaces being processed leaving plastic and rubber components uncoated. It’s this attention to detail and drive to provide our customers with the best possible products and finishes that makes Henkel the world’s leading autophoretic coating suppliers.

Autophoretic Coating vs. E-coating

Henkel’s BONDERITE^® M-PP advanced coating system for ferrous metals provides users with benefits in coating quality, operational efficiency, environmental responsibility, and cost reductions, making the autophoretic coating vs E-coat applications worth reviewing.

Making the switch from a conventional painting process or installing a new autophoretic process to BONDERITE^® M-PP technology is straightforward. Furthermore, the return on investment is recovered quickly through greater operational efficiency and reduced operational and energy costs. To help you improve your process efficiency, our team will work with you to help you assess your current process, establish main objectives, and decide upon the necessary steps to implement the changes efficiently and with minimal disruption.

Key features and benefits of the BONDERITE^® M-PP autophoretic coating process include:

• Professional assessment of current plant and objectives
• Greater overall plant efficiency
• Better quality finish
• Quick return on investment with any installation
• Reduced energy requirements when compared with traditional pretreatment/electrocoat or pretreatment/electrostatic applications.
• Environmentally sustainable

Simple, Automated Bath Control

The autophoretic coating process is a simple, seven-step process with minimal processing control parameters. The necessary autophoretic coating chemicals are a replenisher and starter, which are required to control and maintain the bath chemistry. Adding water is also necessary to control the bath-operating level.

Improved corrosion performance on complex ferrous parts

BONDERITE^® M-PP autophoretic coating provides excellent adhesion and corrosion protection, meeting multiple industry requirements. Because of the coating mechanism, vulnerable areas such as cavities or sharp metal edges are not compromised.

As an example, in Neutral Salt Spray tests (NSS), the autophoretic coating exhibits excellent corrosion resistance up to 1000 hours of testing. The autophoretic coating offers excellent flexibility and can be used as a stand-alone system or as a primer before top-coating.

BONDERITE^® M-PP autophoretic coating offers:

• Exceptional adhesion and corrosion protection
• Excellent flexibility
• Edge and cavity protection
