Filed:

Dec 9, 2004

Appl. No.:

11/008686

Inventors:

Michael D. Radl - Rock Hill SC, US
James G. Ellison - Chester SC, US
Nolan R. Stewart - Catawba SC, US

Assignee:

Rhodia Chimie - Aubervilliers

International Classification:

C08G 77/08

US Classification:

528 15, 528 31, 528 32, 525478

Abstract:

The invention is directed to a thermal addition curable solventless silicone release composition having a reduced coefficient of friction and improved slip characteristics. The invention is also directed to a method for producing a thermal addition curable solventless silicone release composition on a substrate by applying the thermal addition curable solventless release composition of the invention to a substrate and curing the coating on the substrate using heat. The invention is further directed to a thermal addition curable solventless silicone release coated article having a reduced coefficient of friction and improved slip characteristics.

US Classification:

428447000, 524860000, 522006000

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 substrate, and release coated substrates formed thereof.
