Abstract:
The present inventions concerns compositions for producing thermoset polyurethanes, comprising polyisocyanates and polyols selected from a list consisting of allicyclic, aromatic compounds and branched polyesters. The films obtained from these compositions exhibit a high transparency, high thermal stability and good chemical resistance, and a method to produce the same. The said polyurethane films can be widely used in electronics industry where high transparency, high thermal resistance and good chemical resistance are the main requirements. Particularly, these films can be used as the substrates for conductive coatings and barrier coatings. These functionally coated films are particularly useful in applications such as touch panels or photo-voltaic cells.
