Product overview
KEPERDISP®-632 is a special dispersant for titanium dioxide, Excellent performance in various resin systems.
Physical data
1. Effective ingredient: Polyester modified phosphate ester
2. Content: 50%
3.Solvent: Xylene
Product features
1.Excellent wetting and dispersibility for titanium dioxide ,dramatically reduces the viscosity of the system. Improve liquidity.
2. Excellent compatibility, good dispersion performance in various resin systems.
3.Effectively improve the hiding power and the gloss of the coating.
4.Good storage stability and dilution stability, highly recommended for pure white paint systems.
Application test
We tested the dispersion performance of KEPERDISP®-632 and B-110 in thermoplastic acrylic acid, synthetic fatty acid, thermosetting acrylic acid amino, two-component epoxy, hydroxyl acrylic acid, polyester /amino systems.
Our dispersed pigments: titanium dioxide
Test and comparison items:dispersion efficiency, viscosity, storage stability，Anti sinking property,covering power.
Test results:
1.Dispersion efficiency:KEPERDISP®-632 , B-110
Dispersion equipment: Disperse with a sander for 1 hour, Fineness: 5 µ
2.Viscosity:The viscosity reduction effect of KEPERDISP®-632 in epoxy and thermoplastic acrylic acid systems is much better than B-110, and the viscosity is similar in other systems.
3.Storage stability:After 30 days of sealed storage in 50℃, the fineness of grinding pastes did not change. The viscosity increase ratio is similar, and no hard precipitation.
4.Covering power and whiteness：The covering power and whiteness of their grinding white paste are very close.
The test results show that the comprehensive performance of KEPERDISP®-632 is close to B-110 .Please contact us for a detailed test report.
