Polyurethane ink with its excellent performance and a wide range of substrate adaptability in the field of inks occupy a growing market share, according to industry statistics, in composite inks, polyurethane inks accounted for more than 60%.
is a dispersed medium in ink, is the carrier of pigment particles, it plays an important role in ink printing suitability. The traditional polyurethane ink connection material has the problem of OPP membrane adhesion is not good, need to rely on the addition of OPP adhesion promoter to improve its performance on OPP membrane, and OPP membrane adhesion promoter relatively high price, directly increase the cost of ink products.
Made a breakthrough in this field, developed OPP adhesion-enhanced polyurethane gravy composite ink connection material WANCOL®905. Even without adhesion promoter at all, its adhesion can still reach about 80%, in the presence of a very small amount of OPP adhesion promoter, its OPP adhesion can reach 100%.
WANCOL®905 also retains all the advantages of traditional polyurethane concave composite connection materials, such as excellent color display, good resoluble, high temperature cooking and so on. In addition to OPP film, with its configuration of ink in PET, NY and other film adhesion performance is equally outstanding. The choice of ® 905, while ensuring the performance of ink products, reduce their costs, will greatly improve the competitive advantage.
