K-SPERSE 131 is a highly effective wetting and dispersing agent for all types of pigments. It is a calcium salt of an alkyl aryl sulfonic acid dissolved in an aliphatic solvent and is recommended for use in solvent borne coatings and inks.

Faster dispersion times
Better color development and gloss
Lower dispersant levels
Better transparency of transparent pigments
Higher pigment loading due to lower viscosity of pigment paste
Improved corrosion resistance
No deleterious effect on catalyst performance

Appearance:                            Clear, dark amber liquid 
% Active:                                  50
Specific gravity, 25°C:              0.93    
Volatile:                                    Mineral Spirits

K-SPERSE 131 is recommended for use as a dispersant for organic and inorganic pigments in most types of resin systems, including alkyd, acrylic, polyester, polyurethane, chlorinated rubber and bituminous. It is particularly recommended for difficult to disperse pigments.

Low optimum use levels range from 0.5%-8.0% of K-SPERSE 131 as supplied, based on total pigment weight. The greater the surface area of the pigments used, the greater the level of K-SPERSE 131 will be necessary for proper dispersion.
