TM Aquence™ Autophoretic® ™ Series Coating Products Product Benefits & Features • Environmentally friendly – no toxic heavy metals, VOCs or HAPs. Autophoretic®, also known as autodepostion or A-coat, is a waterborne process Another characteristic of the Autophoretic® coating process is that is quite. Autophoretic® -- Coating Solution for Metal Parts Unique Characteristics of Henkel Bonderite Coating Performance Characteristics(PDF) · If you have 3 .

Since its inception, this unique process has been employed to coat billions of square feet of surface. Presently, there are numerous installations in operation, both captive and job-shop, coating a variety of fabricated steel parts for the automotive and general industry markets. The bath viscosity is close to that of water with little or no organic solvents in the coating bath.

The mildly acid bath liberates a small amount of iron from the steel parts being immersed, causing an immediate surface reaction that releases iron ions.

These ions interact with the latex in solution causing coating deposition on the surface of the steel parts. The newly deposited organic film is adherent yet quite porous.

This allows the chemical activators to diffuse rapidly in the film and etch the surface of the metal. The continuous formation of coating provides a film with a high degree of surface protection and corrosion resistance.

The coating thickness of the autodeposited film is time and temperature related. Initially, the deposition process is quite rapid, but slows down as the film increases in thickness. Therefore, Henkel provides a free test coat of components, enabling customers to evaluate the process and its performance.

The typical process Autodeposition lends itself to production using chain conveyor systems, hoist systems and power and free mechanisms. Theoretically, no electrodes are necessary for the process so flood coating is possible. Performance on production parts or other substrates may vary. Figure 9 U. Life cycle testing for parts is recommended.

Applications include any ferrous metal part or structure requiring superior cyclic corrosion protection, thermal stability and good top coat ability. The ability of Aquence G to provide a lighter color primer base and precise film thickness enables decreased paint consumption and improved top coat color control.

This epoxy-acrylic urethane coating has excellent thermal stability, top coat ability and flexibility. Autophoretic Coatings provide the same level of functional performance experienced with baking enamels, electro-plating, electro-coating and powder-coating technologies. Henkel directly maintains or licenses technical, manufacturing and business development support for this unique technology in every region of the world.

A sample of typical commercial applications is noted below.

Smart Coating Solution

The autodeposition coating process has a number of unique features and benefits: 1. No throwing power limitations Autodeposition is not limited by electrical shielding wherever the liquid wets, it will coat. Alf Engineering has selected autodeposition coatings to give long term corrosion protection to the inside and outside of the chassis frames.

Compared to sprayed processes, the benefits of higher jig loading can be extensive. The photograph below right shows the high capacity loading that can be achieved with ACC.

Ability to coat complex assemblies The oven baking schedule for ACC is C F , a temperature at which most rubber and plastics remain undamaged. This means rubber and metal anti-vibration mountings can be coated without damage to the rubber, and rubber seals remain undamaged.

Rubber and metal suspension mountings coated with ACC The autodeposition coating process creates real and permanent cost-reduction options for manufacturers coating metal components as assemblies.

If product designs allow for a coating process that is selective for the substrates that it touches, the following opportunities are possible: Lower freight impact ability to direct ship to end-users Decreased rack investment and maintenance Improved manufacturing cycle time Reduced packaging costs Decreased in-process inventory and indirect labor Photo courtesy of Autocoat Ltd.

This benefit of ACC means that complex assemblies can be painted fully assembled rather than as components. Metal profile reproduction 5. Environmental benefits ACC paint products are water based, have very low or no Volatile Organic Compounds VOC and can meet all known clean air legislation requirements.

All ACC paint products contain no heavy metal anticorrosive pigments, allowing for no settlement problems and enabling facilities to be completely closed over shutdowns.

SEM photos show a uniform, tight autodeposited wet film and consistent coating thickness around the edge of a razor blade.

Autodeposition coating conforms to the shape of the metal surface, and is not affected by variances in electrical energy at high and low areas of complex parts. This feature means ACC provides exceptional edge protection compared to other paint processes. Screw threads often do not require masking when using ACC, offering a significant advantage over other coatings.

Abrasion resistance Parts subject to heavy mechanical wear will benefit from the ACC process due to its exceptional hardness of and its direct bond to the metal.

Automotive seat track slide coated with ACC Because of its exceptional wear resistance, ACC is used on automotive seat tracks, drawer slides and some applications traditionally served by electroplating.

Additional benefits Health and safety No flammable or explosive chemicals in process. Less risk of employee exposure to process.

Fewer limitations on process location. Energy and cost savings Lower energy demands because no electricity is needed to drive the deposition of the coating. No electrical contact needed. Rack build-up is very slow. Decreased rack stripping costs. Conclusion The autodeposition coating process is a simple and reliable industrial finishing system. It has a long and global record of providing uniform protective coatings to the automotive, metal furniture, agricultural equipment and appliance industries.

Autophoretic and Aquence Coatings provide remarkably uniform coatings that provide unique advantages, including coating complex metal and non-metal assemblies and conducting post forming operations on coated parts.The purpose of applying the coating may be decorative, functional, or both.

The continuous formation of coating provides a film with a high degree of surface protection and corrosion resistance.
