Features and advantages VOK ?- Disper W909 is a wetting and dispersing agent for highly filled unsaturated polyester casting systems. It can reduce the viscosity of polyester casting system (polymer concrete, artificial marble, artificial agate). VOK ?- Disper W909 can also improve the flow and leveling properties of the pellets, and has no effect on their curing and finished product color.

Recommended dosage

0.5-1.5% additives (purchased form) are based on the amount of filler. When the filler content is more than 75%, the additive amount should be 1-2% of the resin.

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

Adding method and processing guidance

In order to obtain good performance, additives must be added to the abrasive before adding solid materials.
