Hybridur 870 Acrylic-urethane polymer Air Products North America Acrylic Resins >> Urethane Acrylic Wood & Furniture Coatings Plastic coating Metal Hybridur 870 polymer dispersion is an NMP-free (<0.2% solvent), developmental, anionically stabilized urethane-acrylic hybrid polymer dispersion. It exhibits excellent wetting, adhesion, barrier and film properties when used in air-dried, baked or crosslinked high performance coatings on a wide variety of metal, wood, plastic and previously painted substrates. Hybridur 870 dispersion is the most costeffective alternative to standard polyurethane dispersions (PUD) available today. It provides enhanced performance properties when compared with conventional PUDs or blends of PUDs and acrylic emulsions in coatings for primer, topcoat and clear coat applications. Hybridur 870 dispersion is easy to formulate and offers rapid dry times. Coatings based on this product provide the same ease of use and VOC compliance of those based on typical waterborne dispersions, but with the added benefits of outstanding durability and UV resistance in both airdried and baked systems. Hybridur 870 dispersion can be used for both clear and pigmented (gloss) coating applications in both interior and exterior exposures on metal, wood, concrete and plastic substrates. Corrosion-resistant primer coatings for metal can also be formulated. Coatings based on Hybridur 870 dispersion have been found to perform similarly to those based on Hybridur 570 dispersion. Performance may be enhanced by heating and/or by cross-inking. Blending of Hybridur 870 with Hybridur 580 dispersion will improve hardness, while blending with Hybridur 560 dispersion will increase elongation. Its performances are urethane-acrylic hybrid patented technology, solvent-free (<0.2%), significantly improved value versus PUDs and PUD/acrylic blends, films with excellent mechanical properties, adhesion to a variety of substrates, and good chemical resistance, rapid dry, one-component (1K) systems, excellent gloss and clarity and superior weatherability. An NMP-free, anionically stabilized urethane-acrylic hybrid polymer dispersion. Used in metal, wood and plastic coatings. Offers very good mechanical properties.
