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.
Traitement pour revêtements de silicone pour doublure après un séchage aux rayons ultraviolets. Le silicone recouvre une doublure afin d'en faciliter l'enlèvement de l'adhésif appliqué à une étiquette. Le silicone, lorsqu'il est liquide, forme une couche sur la doublure. Des rayons ultra- violets sèchent le silicone liquide et le transforment un une couche cohérente qui est pratiquement à l'état solide. Le chauffage de la couche séchée de silicone et le fait de le laisser reposer pendant une courte période permettent sa mise en contact immédiate avec l'adhésif du côté de l'étiquette, sans rendre inséparable la doublure enduite de silicone de l'étiquette enrobée d'adhésif.
