Dispersant EMP-4311

Dispersant EMP-4311 is a high molecular weight block copolymer solution of polyether containing pigment affinity groups, which does not contain VOC and APEO polyether block dispersant is used in water-based industrial paints, wood paints, inkjet, printing ink, adhesives, leather pastes and other industries. 

It is suitable for wetting and dispersing resin-free and resin-based organic and inorganic pigment matte powders. 

A water-based general-purpose dispersant that is resistant to acids and alkalis, alcohol, and has a very wide tolerance.

Advantage
