Abstract (en)
[origin: WO9413474A1] A silicone release film including a biaxially oriented PENBB film having a coating thereon in an amount sufficent to act as a silicone release film. The coating comprises glycidoxy silane and an aqueous based thermosetting silicone release composition. The glycidoxy silane present in the coating is at least 0.3 % by weight. Typical glycidoxy silanes are glycidoxypropyltrimethoxysilane or glycidoxypropyltriethoxysilane. A process for coating a PENBB film with a silicone coating is also disclosed, where the coating occurs in-line, during the manufacturing process for the film before it is heat-set. PENBB is a copolyester containing units of formula (I).
