The dispersants solvent-based coatings, Germany BYK161 High molecular weight wetting and dispersing additives. Through steric stabilizing effect to prevent pigment flocculation, and thus the tinctorial strength and hue of the pigment in the paint and pigment paste stabilized. DISPERBYK? -161 Improved pigment wetting, reduce the time required for the grinding process and to improve the gloss and leveling, to reduce viscosity and to avoid thixotropy. This aids the pigment with the same charge, thereby preventing the flocculation of different pigments may, due to the molecular weight and the same as the resin structure, DISPERBYK? -161 Does not affect the paint base material durability. DISPERBYK? -161 Optimized for automotive coatings and high-quality industrial system. In this DISPERBYK? -161/162/163 Lineage, it has the highest molecular weight of the product, and is extremely compatible with the polar system. DISPERBYK? -161 In the use of the products DISPERBYK? A -160 preferred variant, its molecular weight distribution, the polarity and performance and DISPERBYK? -160 Very similar.
