PUD · Ink & Coating
YT-615 is a waterborne anionic aliphatic polyurethane dispersion independently developed by our company. The emulsion is eco-friendly — free of formaldehyde, nonylphenol, heavy metals, PAHs and DMF. It offers good mechanical properties and forms smooth, transparent films with high gloss, light-fast and yellowing-resistant. It is used for metal surface protective coatings, delivering high hardness together with water, solvent, abrasion, anti-corrosion and insulation performance; shows good adhesion on PVC and PET, and is widely applied in various plastic coatings.
