The invention is directed to a polymeric microparticle containing silicone release composition having improved slip/shear, anti-block, transfer, and lower release properties. The silicone release composition may be formed of thermal or radiation cured solventless silicone release compositions. The silicone release composition may also be formed of a UV-cationic silicone release composition. The polymeric microparticles are preferably polymeric microspheres. The invention is further directed to the use of such microparticle containing silicone release compositions to coat a substrates formed thereof.
L'invention concerne une microparticule polymère contenant une composition de libération de silicone présentant des propriétés améliorées de glissement/cisaillement, d'antiadhérence, de transfert et libération faible. La composition de libération du silicone peut être formée par des compositions de libération de silicone sans solvant durci par rayonnement. Ladite composition peut également être formée par une composition de libération de silicone cationique à UV. Les microparticules polymères sont de préférence des microsphères polymères. L'invention concerne, de plus, l'utilisation desdites microparticules contenant des compositions de libération de silicone, ce qui permet de recouvrir un substrat et de libérer des substrats recouverts.
