Product features and advantages

Anti phase separation agent used in PS-UP mixture. It can improve the dispersion and stability of pigments in low shrinkage systems. In HMC, VOK ®- Disper W972 optimizes glass fiber infiltration to improve mechanical properties.

Recommended dosage

0.5-1% additive (purchased form) is resin based and used to prevent phase separation.

0.5-1% additive (purchased form) is based on glass fiber content and used for glass fiber infiltration.

30-140% of auxiliaries (purchased form) are pigment based and used to stabilize organic pigments and carbon black pigments.

The above recommended dosage is for reference, and the appropriate dosage shall be determined through a series of tests.

Adding method and processing guidance

VOK ®- Disper W972 should be added into the resin mixture and mixed evenly before adding pigments and fillers.
