Term:UV-Cured Coating

Category: Coatings

Definition: UV-cured coatings are surface treatments that consist of photo-reactive monomers, oligomers and photoinitiators that exhibit fast polymerization when subjected to UV radiation. This process produces a durable crosslinked coating of film that has high adhesion, chemical resistance and surface protection capability. UV cured coatings are environmentally-friendly due to the very little to no volatile organic compounds (VOCs) they contain, and the short curing time. They are consistently used in the medical, optical, automotive and electronics industries as capable surface-finishing coatings.

How They Work: When UV light shines on the coating, chemicals called photoinitiators absorb the light and start a fast reaction that hardens the liquid coating into a solid layer within seconds. This method doesn’t need heat, saves energy, avoids harmful solvents, and creates a smooth, strong, and well-controlled surface.

Common Uses:

• Medical device coatings (catheters, guidewires, syringes)
• Optical lenses and electronic components
• Automotive topcoats and plastic parts
• Protective and decorative coatings requiring fast curing and high durability
