XR-3140
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%
Solvent: xylene/butyl acetate
Acid value (mgKOH/g): 8-13
Amine value(mgKOH/g):8-13

Characteristic
It has good wetting and dispersing ability for all kinds of pigments.
It reduces the viscosity of the grinding system, increases the pigment content, and at the same time has a strong ability to prevent flocculation and coarsening, and prevents floating colors and blooming.
Good dispersion effect especially for titanium dioxide.
Scope of application
Paints: Used in general industrial, wood and coil paints. Can be used for acrylic, alkyd, polyester, epoxy and other resin systems.
Addition amount and application method
Pigment type Recommended dosage (hyperdispersant to pigment weight percentage)
Inorganic pigment 5-10%
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.
