Hydran HW 311-W-45 Polyester polyurethane-urea Reichhold PU - Polyurethane dispersions (PUDs) >> Polyester PU ADHESIVE >> Water-based HYDRAN HW 311-W-45 Polyurethane Emulsion polyurethane-urea emulsion, water reducible anionic polyester polyurethane-urea, free of emulsifiers and organic solvents, aromatic isocynate excellent adhesion to many plastic substrates (part. PVC) and alumin. high flexibility high peeling resistance resistant to heat (up to 100°C, crosslinked film) 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, water reducible, anionic polyester polyurethane-urea 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.
