UV-Curable Optically Clear Hard Coatings for Plastic Substrates
Superior Scratch, Abrasion, and Chemical Resistance
UV-curable optically clear hard coatings are engineered for superior scratch, abrasion, and chemical resistance providing increased protection that results in extended film life. These coatings offer excellent transparency and low haze characteristics, maintaining optical clarity over time for better performance and aesthetics. Dymax optically clear coatings are used in applications requiring thin protective coatings on various film substrates such as TAC, PET, PC, and PMMA. These optical coatings are formulated to cure with Dymax's broad-spectrum UV light curing equipment.
Optically clear hard coatings for plastics are typically used in the manufacture of electronic touch-panels, polarized sunglasses, safety glasses and goggles, and LCD polarized displays.

Benefits of using UV-curable optically clear hard coatings include:
- Superior scratch, abrasion, and chemical resistance. These coatings have an enhanced ability to withstand damage from sharp objects and the ability to withstand wear from the rubbing of an object.
- Excellent transparency, and low haze characteristics. Clear, hard optical coatings with very low haze.
- Low cost, high volume manufacturing. These coatings are developed to provide cost savings in production, energy, and shipping. The 100% solids in these products allow for reduction in freight costs when compared to products which contain solvents. Without solvents, the ambient production process will have an increase in throughput with a decrease in energy costs. There is also a reduction in waste disposal costs as well.
