Tribological Properties

ATSP coatings can be applied via solvent-borne, electrostatic, and thermal processes. The various coating technique have been used to yield high quality, commercial grade coatings with excellent thickness uniformity, smoothness, adhesion, and tribological properties. Contact us for more details or to have your samples coated with ATSP for evaluation.
