DISPERBYK-171 is a high molecular weight block copolymer additive that acts as a wetting and dispersing agent to produce pigment concentrates. DISPERBYK-171 deflocculates pigments through steric stabilization, resulting in improved color strength and reduced viscosity allowing for higher pigment loading. It prevents floating or flooding of pigments even in complex pigment combinations and difficult colors. DISPERBYK-171 provides benefits such as uniform dispersion of pigments during production, enhanced color consistency and hiding power. It can be used while manufacturing pigment concentrates for various applications where consistent pigment dispersion and rheology control is required.
