Hybridur 580 Acrylic-urethane polymer Air Products North America Acrylic Resins >> Urethane Acrylic Wood & Furniture Coatings Plastic coating Metal HYBRIDUR polymer dispersions are a line of anionically stabilized acrylic-urethane hybrid polymers from Air Products. These innovative materials have been found to exhibit excellent wetting, adhesion, barrier and film properties when used in air dry, baked or crosslinked high-performance coatings on a wide variety of metal, wood, plastic and previously painted substrates. HYBRIDUR dispersions offer the formulator a cost-effective alternative to standard polyurethane dispersions (PUD) without sacrificing performance. They also offer enhanced performance properties over blends of PUDs and acrylic emulsions in coatings for primer, topcoat and clear coat applications. HYBRIDUR dispersions are easy to formulate and they offer rapid dry times. They provide the same ease of use and VOC compliance of typical waterborne dispersions with the added benefits of outstanding barrier properties, durability and UV resistance in both air dry and baked systems. HYBRIDUR 580 dispersion was designed for use in wood coating applications or to provide an improved hardness material for use with HYBRIDUR 570 dispersion in metal, concrete or plastic coating applications. It is a hard, sandable and buffable polymer that must be adequately coalesced to deliver maximum performance. It has good UV and yellowing resistance on exterior exposure. It can be blended with HYBRIDUR 570 to improve its film formation at reduced co-solvent levels. Performance can be enhanced by heating and/or by crosslinking. It possesses outstanding adhesion to a wide variety of substrates, fast dry times— <30 minutes. Touch-dry, 1 hr dry-hard, weathering resistance and water hold out, superior chemical and solvent resistance properties, resistance to a large variety of stains (particularly those required for KCMA1 and MFMA2 qualification), and mild acid and caustic resistance.and mild acid and caustic resistance, good UV stability and gloss retention for topcoats—∆E<2 and 80% gloss retention after 1-year Florida exposure, films with excellent mechanical properties, especially at low temperatures, good mechanical and thermal dispersion stability. Passes 10 freeze-thaw cycles, excellent early block and abrasion resistance. Acrylic-urethane hybrid polymer. Used for wood, plastic, concrete and metal coating applications. Offers fast dry time. Possesses superior chemical resistance properties. Provides good mechanical and thermal dispersion stability. Exhibits very good early block resistance.
