Wetting and Dispersing Additives HH2346W

• Wetting and Dispersing Additives HH2346W

HH2346W wetting and dispersing agent is a styrene and maleic acid anionic copolymer aqueous solution. Its molecular chain contains both hydrophobic styrene units and hydrophilic maleic anhydride units, giving it unique dispersing and stabilizing functions. It has very good wetting, dispersing and viscosity reduction effects on organic pigments. It is used for water-based production of resin-free color pastes and is VOC-free.

It has a viscosity reduction effect on organic pigments and carbon black, increases the tinting power and gloss of pigments, and also has a very good viscosity reduction effect on inorganic pigments. It has a strong dispersing ability for fillers.

• Incorporation and Processing Instructions

To achieve the best performance, the additives should be added to the grind first, followed by the pigment. Premix the resin and solvent components of the grind, then slowly add the additives while stirring. Do not add the pigment until the additives are well mixed.
