Motor Slot Insulation

CAPLINQ supplies a range of industry standard insulating coating powders that drive the automotive industry.

Industry standard epoxy coating powders

DK7-0953M Coating Powder

Extremely stable, Class F rated insulation epoxy coating powder for electric motor armatures and stators.

Exceptional Shelf-Life at Room Temperature

Epoxy Coating Powders for Slot Insulation of Motor Armatures

Tailor-Made Coating Powders

Over the years, SolEpoxy has developed two important epoxy coating powders. The first epoxy coating powder is used on automotive “enclosure” motors, window lift motors and wiper motors. The second epoxy coating powder was specifically developed for fuel pumps.

DK7-0953M for Coil Winding Applications

DK7-0953M is a light blue coating powder for rotors and stators within Motor Armatures. This epoxy coating powder is used extensively by one of the biggest suppliers in the world of electric windows, wiper motors, and electric seat adjustments. This epoxy coating powder gives a beautiful result when coating using an Electrostatic Fluidized Bed coating machine. To our knowledge, it has the best edge coverage of all manufacturers of functional coating powders, which is very important for these applications.

DK15EG-05 for Contact with Automotive Fluids

DK15EG-05 is available in either black or green color and is a “solvent resistant” coating for smaller rotors and stators. This epoxy coating powder was tailor-made for a major, Tier 1 automotive supplier of car and mini-van fuel pumps. In addition to the excellent edge coverage, the DK15EG-05 is resistant against a range of automotive fluids including gasahol. It can also be used as an alternative to DK7-0953M if customers need specifically a black- or green-colored epoxy coating powder.
