Abstract
The invention relates to a method of applying polymeric materials to the surface of a substrate by providing a layer of polymeric material on a release sheet and then subsequently transferring the polymeric material from the release sheet by the application of heat and pressure sufficient to effect adhesion of the polymeric material to the substrate and thereafter peeling the release sheet from the polymeric material. The invention is particularly concerned with the application of polymeric materials being capable of a secondary reaction at the time of application to the substrate or subsequent thereto.
Claims7
A polymeric article adapted for heat and pressure transfer to a substrate, said article comprising
- a layer of composite polymeric material having temporarily adhered thereto a sheet material adapted to act as a release sheet, said composite polymeric material being adapted to be secured to a substrate on application of heat and pressure sufficient to tackify said material and allow the release sheet to be removed;
- wherein components of said composite polymeric material are capable of undergoing an interraction which modifies its chemical structure when a temperature significantly higher than the tackifying temperature is applied in the absense of pressure and after the article has been secured to the substrate and the sheet material removed from the article.
