EVONIK: Radiation Technology Systems
These RC silicone systems are acrylate-modified silicones, specifically designed to cure with ultraviolet light (UV) or electron beam (EB) energy. TEGO RC Silicones are silicone functional polymers that are 100% oligomeric and solvent-free. The technology is commonly used in applications for bottle, cosmetic, hygiene and food labeling, as well as industrial applications.
The two UV-curable silicone release systems produce release coatings without the use of heat, but differ in their underlying chemistries. The first is based on silicone acrylate and cures via a free-radical mechanism, while the other release system uses epoxy silicones and cures in the presence of a cationic photo catalyst. Standard medium-pressure mercury UV lamps (arc lamps) or microwave-induced UV lamps (as used in normal UV printing and coating processes) can be used to cure both types of silicones.
