Performance:
This agent causes the pigment to deflocculate through steric
hindrance stabilization.
Due to the small particle size of the flocculent pigment, it can
achieve high gloss and enhance color strength.
In addition, the transparency of transparent pigments and the
covering power of opaque pigments have also been improved. Due to
the decrease in viscosity, the fluidity is improved and the pigment
content can be increased.
Application:
1. Especially suitable for producing stable resin free pigment
shrinkage, with a pigment content of 30-60%.
2. Recommended for producing stable resin free pigment concentrate
slurry to prepare water-based coatings without floating or
blooming.
3. Water-based adhesives (rational choice), epoxy system,
polyurethane system
Recommended addition and Usage:
To obtain ideal performance, the dispersant needs to be slowly
added (under stirring) to the mixture of grinding resin/cosolvent
or lotion resin. When used in resin free pigment concentrated
slurry, before adding the pigment, mix the dispersant and water
evenly.
