德国Wesel的BYK-Chemie公司推出固体着色剂含量高的色母料生产用浸渍剂和分散剂新产品Disperbyk-2155。固体着色剂含量高的母料要求用高分子助剂,但其分散性一般都不好。为克服这种缺点,BYK公司开发出100%高分子量、流动性优良的嵌段共聚物作为分散剂。与传统线型结构分散剂相? BYK-Chemie, of Wesel, Germany, has released Disperbyk-2155, a new product for impregnation and dispersions for the production of masterbatches with high solids colorants. High concentrations of solid colorant masterbatch require the use of polymer additives, but the dispersion is generally not good. To overcome this shortcoming, BYK developed a 100% high molecular weight, highly fluid block copolymer as a dispersant. With the traditional linear dispersant phase?
