Hydran HW 311 NY-W-45 Polyester polyurethane Reichhold PU - Polyurethane dispersions (PUDs) >> Polyester PU ADHESIVE >> Water-based HYDRAN HW 311 NY-W-45 Polyurethane Emulsion polyurethane emulsion, water reducible aliphatic polyester polyurethane, free of emulsifiers and organic solvents excellent adhesion to many plastic substrates (part. PVC) and alumin. high flexibility high peeling resistance resistant to heat (up to 100°C, crosslinked film) not yellowing primers for plastic (in part. e.g. for PVC and PUR foam) adhesives for plastic and aluminium 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, not-yellowing, water reducible aliphatic polyester polyurethane emulsion. Used in adhesives for plastic and aluminium. Provides high flexibility, high peeling resistance and resistance against heat. Can be crosslinked with water reducible melamine resins.
