- Advantages
- Improves pigment wetting and reduces grinding/dispersing times
- Better color development and gloss
- Very effective at lower dispersant levels
- Higher pigment loading due to lower viscosity of pigment paste
- Improvesjetness of black pigments
- Better transparency of transparent pigments
- Enhances catalyst performance in amino crosslinked systems
- Improves humidity and corrosion resistance

- Applications
K-SPERSE 152 is recommended for use as a dispersant for organic and inorganic pigments in most types of resins systems, including alkyd, acrylic, polyester, polyurethane, chlorinated rubber and bituminous. It is particularly recommended for hard to disperse pigments.
- Incorporation
K-SPERSE 152 should be dissolved in the mill base prior to pigment addition.
- Typical Usage Levels
Low optimum use levels range from 0.5% - 8.0% of K-SPERSE 152 supplied, based on total pigment weight. The greater the surface area of the pigments used, the greater the level of K-SPERSE 152 wll be necessary for proper dispersion. As a guide, we recommend the following approximate amounts of K-SPERSE 152 to use for the following pigments :
Pigment Pigment Surface Area mg K-SPERSE per m² of Pigment Lbs K-SPERSE per 100 LBS PigmentRutile Titanium Dioxide 13 m²/g 0.46 0.6 Phthalocyanine Blue 67 m²/g 0.52 3.5 Transparent Iron Oxide 93 m²/g 0.54 5 High Color Carbon Black 560 m²/g 0.13 7 Follow these guidelines to determine the weight percent of K-SPERSE needed per 100 pounds of pigment
- For most pigments : K-SPERSE level (wt%) = 0.05 x pigment surface area (m²/g)
- For carbon black pigments: K-SPERSE level (wt6) = 0.013 x pigment surface area (m²/g)
