Abstract
A treatment for silicone liner coatings after undergoing UV curing. The silicone coats a liner to facilitate its removal from the adhesive attached to a label. The silicone, while a liquid, forms a layer on the liner. UV radiation cures the liquid silicone and causes it to become a coherent, virtually solid layer. Heating the cured silicone layer and allowing it to rest for a short period of time then permits the immediate contact with it of the label's adhesive side without incurring inseparability of the silicone-coated liner from the adhesive-coated label.
