L-6380A-4 is a specially modified, fully solid matte polyurethane acrylate UV resin with no irritating volatiles. After curing, it forms a 5–10° gloss film with stable matte finish, excellent scratch and abrasion resistance, and nano-level fineness. The resin is halogen-free, environmentally compliant, maintains its matte properties regardless of baking conditions, and shows less than 1% volatilization with very low odor when baked at 80°C for 2 hours.
