Features and Benefits

Wetting and dispersing agent for low ripple/low shrinkage and high filling epoxy systems. It is also applicable to the stability of viscosity in BMC.

Recommended use

Low ripple and Class A surface formula

Low shrinkage formula

Epoxy system

Pultrusion forming

Stable viscosity in BMC

Recommended dosage

When used for wetting and dispersing, 1-2% additives (purchased form) are based on the amount of filler.

When used to stabilize viscosity in BMC, 0.5-2% additives (purchased form) are based on resin amount.

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 W995 shall be added to the resin mixture before uniformly mixing and adding pigments and fillers.
