| Aliphatic, acrylate-modified polyurethane dispersion. Binder for waterborne, air- and oven-drying basecoats in two-layer systems for automotive coatings, coatings for plastics, automotive refinishing coatings, industrial coatings and stone chip functional coatings. Properties / Applications: When used in two-layer systems with TSA and two-component polyurethane clearcoats, metallic basecoats formulated with Bayhydrol® UA 2856 XP are characterized by even, cloud-free films with a very good flop effect, excellent gloss and good hiding power. The metallic basecoat can be oversprayed with TSA or two-component polyurethane clearcoats after pre-drying e.g. for 5 min at an oven temperature of 80 °C. Based on its high flexibility Bayhydrol® UA 2856 XP is also suitable as a binder for coatings that are highly resistant to stone chipping, such as stone chip primers.
