Title
(EN) RADIATION-CURABLE ORGANOPOLYSILOXANE RELEASE COMPOSITIONS
(FR) COMPOSITIONS D'ORGANOPOLYSILOXANE POUR COUCHE ANTIADHESIVE DURCISSANT SOUS L'EFFET DE RADIATIONS
Abstract
(EN)
A radiation-curable release composition is disclosed which comprises: (A) an organopolysiloxane represented by the formula (I): RSi(CH3)2-O-(Si(CH3)2O)n(Si(CH3)(R)O)mSi(CH3)2R, wherein in Formula (I), each R is -R1-O(O)C-C(R2)=CH2, -R1-O-C(R2)=CH2 or (a); R1 is a hydrocarbylene group; each R2 is independently hydrogen or a methyl or ethyl group; m is a number from about 1 to about 15; and n is a number from about 50 to about 300; and (B) an organosiloxane copolymer represented by the formula (II): (R3SiO)x(SiO4/2)y, wherein in Formula (II), each R is independently a hydrocarbon group or a group represented by the formula: -O(O)C-C(R1)=CH2, wherein R1 is hydrogen or a methyl or ethyl group; x is a number from about 0.25 to about 75; y is a number from about 1 to about 56; and the ratio of x to y is from about 0.3:1 to about 1.5. In one embodiment, the inventive release composition further comprises (C) an acrylate represented by the formula (III): CH2=C(R1)-C(O)O-R2, wherein in formula (III), R1 is hydrogen or a methyl or ethyl group, and R2 is a hydrocarbon group of about 10 to about 24 carbon atoms. A method of producing release-coated substrates, the release-coated articles thus produced, and multi-layer articles or constructions incorporating a release layer also are disclosed. When the release compositions are cured such as by radiation, the cured compositions exhibit a desirable high and controlled release force at high speeds such as the speeds utilized in label processing.

Compositions pour couche antiadhésive durcissant sous l'effet de radiations comprenant: (A) un organopolysiloxane de formule (I): RSi(CH3)2-O-(Si(CH3)2O)n(Si(CH3)(R)O)mSi(CH3)¿2R, où chacun des R représente -R1-O(O)C-C(R2)=CH2, -R1-O-C(R2)=CH2 ou la formule (a) dans lesquelles R1 représente un groupe hydrocarbylène, et chacun des R2 représente indépendamment hydrogène ou un groupe méthyle ou éthyle; m vaut un nombre compris entre environ 1 et environ 15; et n vaut un nombre compris entre environ 50 et environ 300; (B) représente un copolymère du type organosiloxane de formule (II): (R3SiO)x(SiO4/2)y, dans laquelle chacun des R représente indépendamment un groupe hydrocarboné ou un groupe représenté par la formule: -O(O)C-C(R1)=CH2, dans laquelle R1 représente hydrogène, ou un groupe méthyle ou éthyle; x vaut un nombre compris entre environ 0,25 et environ 75; y vaut un nombre compris entre environ 1 et environ 56; et le rapport x/y est compris entre environ 0,3/1 et environ 1,5. Dans l'une des variantes, la composition objet de l'invention comprend en outre (C), un acrylate représenté par la formule (III): CH2=C(R1)-C(O)O-R2, dans laquelle R1 représente hydrogène, ou un groupe méthyle ou éthyle, et R2 représente un groupe hydrocarboné comprenant entre environ 10 et environ 24 atomes de carbone. L'invention porte également sur un procédé de production de substrats à revêtement antiadhésif, sur des articles à revêtement adhésif ainsi produits, et sur des articles multicouches ou des réalisations à revêtement antiadhésif. Lorsque les compositions antiadhésives ont durci notamment sous l'effet des radiations, elles présentent une force de séparation élevée et contrôlée requise à des vitesses élevées telles que celles utilisées dans le traitement des étiquettes.
