Product overview
KEPERDISP®-6090 is a high performance dispersing agent for preparing water-based general purpose color pastes. excellent dispersion performance and viscosity reduction effect, outstanding stability.
Physical data
1. Effective ingredient: Block polymer containing pigment affinity groups
2. Content: 40%
3.Solvent: Water
Product features
1.Wide versatility, suitable for water-based color pastes(resin free or containing resin ). excellent dispersion properties for titanium dioxide, inorganic/organic pigments and carbon black.
2.Excellent viscosity reduction effectively ,Strong color display ability for organic pigments, carbon black .
3.Excellent storage stability, strong anti-floating color ability.
4.Especially when grinding titanium dioxide, the whiteness of the paste is prominent, and the white paste is not easy to float when mixed with other colors.
Application test
We tested the dispersion performance of KEPERDISP®-6090 and T-755W to prepare resin-free color pastes.
Our dispersed pigments:Carbon black# 6,Iron oxide red,Phthalein blue,Titanium dioxide
Test and comparison items:dispersion efficiency, viscosity, color rendreing, transparency, anti-flocculation ability, storage stability,Anti-floating color ability.
Test results:
1.Dispersion efficiency:KEPERDISP®-6090 , T-755W
Dispersion equipment: sand mill,Dispersion fineness: 5 µ
Dispersion time to fineness: Carbon black (less than 6 hours), Phthalein blue(less than 4 hours),
Titanium dioxide(less than 1 hour).
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.Anti-floating color ability:After the grinding paste is mixed with white, observe the degree of floating color, and they are similar.
The test results show that the comprehensive performance of KEPERDISP®-6090 is close to T-755W .Please contact us for a detailed test report.
