Abstract
Compositions of polyolefins having from 0.5 to 80% by weight of unstabilized polyethylene powder and from 20% to 99.5% by weight of a stabilized polyolefin powder. These powdered compositions have superior adhesion to metallic objects and can be applied directly to heated metallic objects to provide the protective coating.
