Study: Comparing two DOXA dispersants’ effects on Raven 5000UII

July 7, 2015ReportsDOXA2015wp

We at DOXA recently conducted a study on the relative effects two of our dispersing agent grades, D-333U and D-335U, have on grinding efficiency and viscosity, as well as the effect pigment particle size has on color and grinding time. The test was conducted on Birla’s Raven 5000UII. The abstract is reprinted below, and the report is available for download in its entirety below.

ABSTRACT:

As coating technology has developed, pigment particle size requirements have become more stringent. As changes in particle size can result in a variety of optical effects, the purpose of the present report is to explore the effect of changes in particle size during the grinding process on the color of the finished product.

The purpose of this report is to determine:

1. The effect of different sized pigment particles on color

2. The effect of different sized pigment particles on grinding time

3. The effect of different formulations on grinding efficiency.

4. The effect of different formulations on viscosity
