Dry Film Lubricants

Donwell applies uniform coatings of dry film lubricants to tolerances from .0002" to .0005". These coatings have molybdenum disulfide and graphite bases and are used for high-load applications, up to 250,000 psi. They have corrosion-resistant properties and are stable over a wide temperature range. They are often used in areas inaccessible to relubrication or exposed to dirt and dust. When used on mechanical components, they minimize metal-to-metal contact, reducing friction and wear.

Dielectric Coatings

Donwell applies a special line of coatings that combine high electrical insulation with excellent heat transfer. These finishes meet the requirements of MIL-E-5272. Typical applications include heatsinks, semiconductors and printed circuit boards.
