BYKJET® -9150

Solution of a structured copolymer with pigment affinic groups. Acts as a wetting and dispersing additive for solvent-borne inkjet inks. Prevents the reflocculation of pigments via steric hindrance and therefore stabilizes the color strength, hue of pigments in inks as well as pigment concentrates. Viscosity of the pigment concentrates as well as the final inkjet inks is reduced and thixotropy is avoided. Long-term storage stability without viscosity shift is achieved. Provides equal electrical charge to the pigment particles and thus prevents possible co-flocculation of particles that are not equally charged. Due to the excellent pigment deflocculation particle size is small and particle size distribution is narrow which strongly reduces filtration time.
