Abstract
The present invention relates to a polymer composition for use in thermal spray coating application comprising an α-olefin homopolymer or copolymer, a functionalized a-olefin homopolymer or copolymer, a polyolefinic elastomer and an anti-corrosion additive. Such polymer compositions have a good long-term corrosion resistance, good coating to substrate adhesion, good long-term adhesion and good long-term weather resistance.
