A method for treating a substrate is described. In accordance with one aspect, the method includes applying a polymer coating to a substrate, and bringing the polymer coating into contact with a heated surface while the coating is still in a wet state. Optionally the polymer coating may include a crosslinkable material, and a crosslinking agent may be used to promote crosslinking. The polymer coating replicates the heated surface. A product produced in accordance with the described method is also disclosed. The product is characterized by having subsurface voids within the coating.
L'invention concerne un procédé servant à traiter un substrat. Selon un mode de réalisation de l'invention, ce procédé consiste à appliquer un revêtement polymère sur un substrat et à mettre le revêtement polymère encore à l'état humide en contact avec une surface chauffée. Le revêtement polymère peut optionnellement comprendre une matière réticulable, un agent de réticulation pouvant être utilisé pour favoriser la réticulation. Le revêtement polymère reproduit la surface chauffée. L'invention concerne également un produit fabriqué selon ce procédé et caractérisé en ce qu'il présente des vides sous la surface du revêtement.
