DISPERBYK®-163 is a high molecular weight wetting and dispersing additive for solvent-borne systems and pigment concentrates. It is composed of solutions of high molecular weight block copolymers with pigment affinic groups.
This product is used in many formulations. For new developments, however, the additives DISPERBYK® 2164 and DISPERBYK®2163 (see Data Sheet W235) should be preferred. DISPERBYK® 163 has an even lower molecular weight than DISPERBYK-162, is less polar and is used primarily in general industrial coatings and to produce pigment concentrates. It has a wider compatibility in various binder types than DISPERBYK® 161 and DISPERBYK® 162. The aromatic-free version of DISPERBYK® 163 is available as the product DISPERBYK® 167.
