Hydran AP 70-W-35 Polyester polyurethane Reichhold PU - Polyurethane dispersions (PUDs) >> Polyester PU ADHESIVE >> Water-based HYDRAN AP 70-W-35 Polyurethane Emulsion polyurethane emulsion, water reducible polyester polyurethane, free of emulsifiers and organic solvents excellent adhesion to plastic substrates, special polyester yellowing resistance excellent flexibility good abrasion and water resistance (crosslinked film) primers and top coats for paper, textiles and highly flexible plastics coatings for highly flexible leather for superior hardness, abrasion and chemical resistance add 1-3% crosslinker Epotuf CR-5L immediate before application (pot life is approx. 12 h at 20°, curing 15 min at 100°C or 1 min at 140°C Crosslinking with water reduceable melamine resins (15-25% solid amino resin, calc. on Hydran solids) is also possible to obtain very flexible, non yellowing films with high chemical resistance; baking conditions depend on the reactivity of the melamine resin Emulsifier-free, organic solvents free, water reducible, polyester polyurethane emulsion. Used in industrial adhesives. Provides very good adhesion to plastic substrates and special polyester. Offers yellowing resistance, very good flexibility, and good abrasion and water resistance. Can be crosslinked with water reducible melamine resins.
