low-molecular-weight dispersing agent
Efka® FA 4644 reduces the interfacial tension between pigments or extenders on one side and the vehicle on the other side. Product benefits are:
• reduced dispersing time
• improved stabilization of the pigment dispersion
• reduced pigment sedimentation
• increased gloss
• improved flow
