Pigment Dispersing Agent “AJISPER”
Advantages
“AJISPER” is a novel pigment dispersing agent developed based on AFT’s surface chemistry technology with a vast reserve of experience. It exhibits prominent effect in dispersing organic and inorganic pigments and carbon black, and thereby enabling substantial improvement in viscosity reduction, shelf life, coating film sharpness, and in mixed color stability.
