Room temperature curing resin system

Product features and advantages VOK ®- Disper W961 is an anti settling additive, especially recommended for polyurethane systems filled with minerals. When propylene glycol is used as the solvent of the auxiliary active substance, it will cross link with isocyanate during curing.

Recommended dosage

0.5-1.5% dosage of additives (purchased form) is based on filler.

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, the additive should be added before adding solids.
