Abstract

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.

Description

technical field

[0001] The present invention relates generally to silicone release coating compositions, the use of such silicone release coating compositions to coat substrates, and release coated substrates formed therefrom. More specifically, the present invention relates to heat-curable, radiation-curable and UV cationic solvent-free silicones having improved slip / shear properties, transfer properties, anti-blocking properties and reduced release properties Barrier coating. Background technique

[0002] Silicone release coatings or compositions are well known and are the subject of numerous publications and patents. They are useful in many applications where a relatively non-adhesive surface is desired. In these applications, the release composition is applied to a substrate and allowed to cure. One particularly useful application is the coating of paper, polyethylene film and other materials used in providing release surfaces, pressure sensitive adhesive labels, deco...
