This UV-curable coating is specially engineered for screen printing on polyethylene (PE) release surfaces, offering excellent adhesion and flexible film formation. It provides a durable, high-gloss or matte finish with fast curing and strong resistance to abrasion and chemicals. Ideal for labels, industrial markings, and specialty graphics on low-surface-energy substrates, it ensures reliable performance and enhanced aesthetics in demanding applications.
Q1: What is the main challenge of coating polyethylene (PE) release surfaces, and how does this product address it?
A: PE surfaces have extremely low surface energy, making adhesion difficult for most coatings. This UV coating is formulated with specialized adhesion promoters and flexible resins that chemically bond to PE, ensuring strong, durable adhesion even on challenging release films or treated PE substrates.
Q2: Why is screen printing the recommended application method for this coating?
A: Screen printing allows for controlled, thicker film deposition (typically 10-30 µm), which is often necessary to achieve sufficient coating integrity and functional performance on low-energy surfaces like PE. It also enables precise application on selected areas, which is ideal for labels, markings, or decorative elements on release films.
Q3: What are the key curing and performance characteristics of this UV coating?
A: It cures rapidly under standard UV lamps (typically requiring 200-400 mJ/cm²), forming a tough, flexible film with excellent scratch and chemical resistance. The cured coating maintains strong adhesion under mechanical stress and is suitable for applications requiring die-cutting, winding, or further converting processes.
