Hybridur 878 Acrylic-urethane polymer Air Products North America Acrylic Resins >> Urethane Acrylic Wood & Furniture Coatings Plastic coating Metal Hybridur 878 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 878 dispersion is a 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 878 dispersion is easy to formulate and offers rapid dry times and high hardness. 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. Their solvent-free nature allows formulating latitude when choosing coalescing solvents. at room temperature. Hybridur 878 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. Because of its high hardness, it is especially suitable for use on floors and furniture. Coatings based on Hybridur 878 dispersion have been found to perform similarly to those based on Hybridur 580 dispersion. Performance may be enhanced by heating and/or by cross-inking. Blending of Hybridur 878 dispersion with other Hybridur polymer dispersions is possible to tailor performance properties such as elongation, adhesion and chemical resistance. Its performances are aliphatic urethane-acrylic hybrid patented technology, solvent-free (<0.1%), significantly improved value versus PUDs and PUD/acrylic blends, produces films with excellent mechanical properties, adhesion to a variety of substrates, rapid dry, one-component (1K) systems, excellent gloss and clarity, superior weatherability. An NMP-free, anionically stabilized urethane-acrylic hybrid polymer dispersion. Used in metal, wood and plastic coatings. Offers very good mechanical properties. Provides good chemical resistance and rapid dry. Possesses very good gloss and clarity and superior weatherability.
