A free paint film is formed and applied to a substrate with heat, pressure, or both. The free paint film includes an outer layer formed from a composition that includes an olefinic material. The olefinic material is an olefin-based block copolymer with an olefin block that is at least substantially saturated and at least one (poly)ester or (poly)ether block, an at least substantially saturated polyolefin polyol having a number average molecular weight of from about 500 to about 20,000 or a derivative thereof, or a combination of both.
On applique une couche de peinture libre sur un substrat, en utilisant de la chaleur, une pression, etc. La couche de peinture libre comprend une couche extérieure formée d'une composition contenant un matériau oléfinique. Ledit matériau oléfinique est un copolymère bloc à base d'oléfine constitué d'un bloc d'oléfine au moins sensiblement saturé et d'au moins un bloc de (poly)ester ou de (poly)éther, et d'au moins un polyol polyoléfinique saturé présentant un poids moléculaire moyen en nombre compris entre environ 500 et environ 20 000, un dérivé ou une combinaison des deux.
