ACC have over 35 years specialist experience applying highly performance powder coatings to driveline components destined for Toyota, Nissan, BMW mini, JLR and the specialist motorsport sector.
Using a specially developed powder formulation, designed to give excellent corrosion resistance, chemical resistance (against gasoline, oil, brake fluid, alkalis and acids), durability especially in terms of chip resistance and visual appearance, ACC have been continually coating Driveline components since 1987. The powder chemistry allows low cure which prevents the heat treatment properties of the component being affected and is 100% epoxy in nature for the best available chemical resistance and overall performance. Previous research by ACC has concluded that parts cannot be subjected to temperatures above 180 Deg C during the powder coating curing stage as hardness and heat treatment properties will be affected. It is for this reason that a low curing epoxy powder coating is the preferred option to ensure product integrity is maintained. In addition, temperature profiling of the product as it goes through the curing oven is a necessary control.
The overall performance in terms of corrosion resistance, chemical resistance, durability, chip resistance and appearance as well as the low cure element makes the epoxy powder coating the right choice for driveshaft components. ACC tests on epoxy polyester powders and associated competitor products have revealed concerns with cure, adhesion, visual appearance as well as requiring significantly higher curing temperatures when compared with the standard ACC epoxy powder coating.
All the various customer engineering performance specifications are able to be met within ACC’s standardised processes. In addition, ACC offer an enhanced coating system by way of an immersion zinc phosphate pre-treatment process coupled with the 100% epoxy powder coating to meet more demanding performance standards.
