Abstract
A release coating that exhibits superior release properties includes about 70% Goldschmidt RC 711 silicone, about 30% Goldschmidt RC 726 silicone and about 3% of total silicone weight photo initiator. The silicone mixture provides a smooth release and better avoids the deleterious effects of aging such as yellowing and flaking. In addition, the silicone mixture is a soft silicone such that it will not come off in a printer. The invention also includes a method of making a release coating and a method of applying a release coating to a substrate.
