摘要:
Release compositions comprising a blend of ethylenically unsaturated fluoroorganopolysiloxane polymers and ethylenically unsaturated non-fluorinated organopolysiloxane polymers are described. The release compositions are dispersed in a solvent system and also contain a catalyst and at least one crosslinker. Both fluoroorganohydrogenpolysiloxane and organohydrogenpolysiloxane are described. Release liners and adhesive articles including cured release compositions are also disclosed.
摘要:
A curable composition comprises: an epoxy silane represented by formula X—Si(OR1)(OR2)(OR3) wherein R1-R3 represent C1 to C4 alkyl groups, and X represents an organic group having at least one oxirane ring; a fluorinated silane represented by formula; wherein: Rf represents a perfluoroalkyl group having from 3 to 5 carbon atoms, R4 represents H or a C1 to C4 alkyl group, and R5-R7 represent C1 to C4 alkyl groups; and a photoacid. Use of the curable composition to coat a phototool, thereby providing a protective coating on the phototool is also disclosed.
摘要:
A low surface energy photoresist composition is described that comprises a silicone-polyether block copolymer, wherein the silicone block comprises 35 wt. % or more of said copolymer. When compounded with a photoresist composition, the composition enables the release of a phototool from the photoresist layer.

A hardcoat composition comprises (a) one or more epoxy silane compounds, (b) one or more epoxy-functionalized perfluoropolyether acrylate oligomers, and (c) photoacid generator.
摘要:
Presently described are articles, such as optical displays and protective films, comprising a (e.g. light transmissive) substrate having a surface layer comprising the reaction product of a mixture comprising a non-fluorinated binder precursor (e.g. of a hardcoat composition) and at least one polymerizable perfluoropolyether polymer. The resulting cured surface layer can advantageously exhibit low lint attraction in combination with low surface energy. Also described are one-step and two-step methods of synthesizing perfluoropolyether polymers having polymerizable ethylenically unsaturated groups.
