Polyurethanes (PU) are a class of polymers whose main chain contains -NHCOO- repeating structural units. It is formed by the polymerization of isocyanates (monomers) and hydroxyl compounds. Due to the strong polar urethane group, it is insoluble in non-polar groups and has good oil resistance, tough... read more

First of all, let us understand how the water-based acrylic resin used in the water-based ink works in the ink. There are the following aspects:1. As a film-forming material of water-based ink, it can stick the pigment on the surface of the substrate, giving the ink a considerable body;2. It can mak... read more
Acrylic resin is a resin made by copolymerization of acrylic esters, methacrylic esters and other olefinic monomers. By selecting different resin structures, different formulas, production processes and solvent compositions, different types and properties can be synthesized Compared with acrylic res... read more
Water-based polyurethane uses water as the main medium and contains no or only a small amount of organic solvents. According to the different formulations and additives, it can be adjusted into coatings, adhesives and other treatment agents. Compared with solvent-based polyurethanes, it has the foll... read more
