PAINT REPLACEMENT FILM WITH POLYMER LAYER CONTAINING POLYURETHANE

摘要

gA paint replacement film comprising a polymer layer comprising a polyurethane produced from a formulation comprising at least one blocked isocyanate. The paint replacement film comprises a liner layer and the formulation comprises at least two polyols in OH weight equivalent ratio in the range 4.5:1 to 1:4.5. The formulation may comprise a colourant and the polyurethane may have a glass transition temperature (T) below 42�C. Also disclosed is a method of producing a paint replacement film by providing a backing layer providing the liquid formulation cast coating the backing layer with the liquid formulation and gelling the liquid formulation thereby forming a polymer layer comprising polyurethane. The paint replacement films are useful for replacing paint on surfaces especially in automotive applications.
