Aromatic polyurethane acrylate UV curable resin for plastic coatings and inks

The chemical name of product ZC6408 is polyurethane acrylate. It is a colorless or yellowish transparent liquid with good flexibility and adhesion. It is mainly used in paper, wood, plastic spraying and ink.The molecule of polyurethane acrylate (PUA) contains acrylic functional groups and carbamate bonds. The cured adhesive has the high wear resistance, adhesion, flexibility, high peel strength, excellent low temperature resistance of polyurethane and the excellent optical properties and weather resistance of polyacrylate. It is a radiation curing material with excellent comprehensive properties. The coating system has been widely used in metal, wood, plastic coating, ink printing, fabric printing, optical fiber coating and so on At present, PUA has become a very important class of oligomers in the field of waterproof coatings. In view of the slow curing speed and relatively high price of PUA, PUA is less used as the main oligomer in the conventional coating formula, and is often used as an auxiliary functional resin. In most cases, PUA is mainly used in the formula to increase the flexibility of the coating, reduce stress shrinkage Improve adhesion. However, due to the excellent performance of PUA resin, the research on PUA is also increasing, and polyurethane acrylate is gradually copolymerized with other types of resins to form hybrid system and developed into aqueous system. In particular, the aqueous system directly uses water to dilute and reduce the viscosity, which makes the coating more environmentally friendly and healthy and reduces the use of active monomers, To a large extent, it makes up for the lack of expensive price of PUA resin, which can expand the application range of PUA resin, reduce or even do not use monomers, effectively reduce the shrinkage of waterproof coating, reduce the internal stress during curing, increase the adhesion of coating and improve the flexibility of coating film.
