Non-ionic wetting and dispersing agent
It does not ionize or charge in water, and has relatively weak adsorption on the pigment surface. It is mainly used in water-based coatings. It is mainly divided into glycol type and polyol type, which can reduce surface tension and improve wettability. Used in combination with anionic dispersants as wetting agents or emulsifiers, widely used in water-based colorants, water-based coatings and inks.

Amphoteric wetting and dispersing agent
A compound consisting of anions and cations. A typical application is a phosphate polymer. These polymers have higher acid values and may affect interlayer adhesion.

Electrically neutral wetting and dispersing agent
The size of the anionic and cationic organic groups in the molecule is basically the same. The entire molecule is neutral, but has polarity.

Polymer type hyperdispersant
Polymeric nonionic dispersants are the most commonly used and have the best stability. Polymer-based dispersants are also divided into polycaprolactone polyol-polyethyleneimine block copolymer-based dispersants, acrylate polymer-based dispersants, polyurethanes, polymer polyethers, or polyester-based polymer dispersants. Etc. Because one end of their anchoring group is entrapped with pigment particles and the other end is entangled with resin, it has better storage stability. In addition, polymer dispersants are not just simple structures, they can also graft and cooperate with each other, and their performance is maximized. Such as Shanggao special chemical Sago-9760 wetting and dispersing agent is widely used in water-based, alcoholic water and other high-polarity industrial coatings, nano universal color paste, ink, pigment inkjet, resin-free color paste system, good color development, Excellent anti-settling performance, prevent floating color, stable performance!
