Wetting and dispersing agents for solvent-based systems
Chemical composition
High molecular weight polyurethane type dispersant, medium polarity.
Physical and chemical parameters
Appearance: light yellow viscous liquid
Active ingredient: 45%
Solvents: xylene/butyl acetate/PMA
Amine value(mgKOH/g):12-18
Density(g/ml,20℃):0.97-0.99
Characteristic
It has good wetting and dispersing ability for all kinds of pigments and shortens the grinding time.
It reduces the viscosity of the grinding system, increases the pigment content, and has a strong ability to prevent flocculation and coarsening and improve storage stability.
Improves gloss and coloring power.
Not easy to crystallize at low temperatures. Especially suitable for dispersed carbon black.
Scope of application
Inks: mainly used in packaging gravure inks ester ketone and aromatic systems.
Paints: Can be used for automotive and refinish paints, general industrial paints, and wood paints. It can be used in acrylic, alkyd, polyester and epoxy resin systems. Especially suitable for the dispersion of hydroxyacrylic acid and thermosetting acrylic resin systems.
Addition amount and application method
Pigment type Recommended dosage (hyperdispersant to pigment weight percentage)
Inorganic pigment 5-15%
Titanium white 2-5%
Organic pigment 20-40%
Carbon Black 25-100%
The dispersant is dissolved completely in the grinding medium before the pigment is added.
