1. Designed for flat to high-gloss interior and exterior wall coatings, with excellent fluidity, leveling and splash resistance.

2. It is a low-cost/high-performance substitute product for cellulose thickener in interior wall coatings.

3. Good formula adaptability.

4. It has good antimicrobial properties.

How to use

1. Adjust the PH value of the coating to make it reach 9-9.5.

2. Dilute PR-328 with water, and the ratio of water to water is 1:1.

3. Under low-speed stirring, slowly add the diluted PR-328.

4. While stirring, observe the viscosity change of the paint. After reaching the specified viscosity, stop adding the thickener.
