Donwell is approved to apply coatings to meet many aerospace, medical, industrial and military specifications, including MIL-PRF-46010. Coatings are applied electrostatically by state-of-the-art methods for ease of application, complete coverage and cost effectiveness. They can be applied to many substrates, including metals, elastomers, composites, rubber, ceramics and glass. Most applications require fusing or baking of the coating. Curing temperatures range from ambient to 1000°F (540°C). Our knowledge of the properties of coating materials from many different manufacturers allows us to apply the right coating to meet each customer's needs. We also offer a liberal prototype and sample policy that enables potential customers to evaluate a coating application prior to production.

The high-performance coatings we work with can be used in an almost unlimited variety of applications. A partial list includes medical parts, electronic devices, hardware, appliance parts, bearings, valves, pumps, gaskets, hand tools, automotive parts and industrial equipment and machinery. We also apply FDA-compliant coatings, including Silverstone® and Supra®, for food processing and consumer-use applications.
