SMC, BMC, pultrusion

Product features and advantages

General purpose, economical wetting and dispersing additives can be used in almost all closed mold applications. It is very effective in highly filled aluminum hydroxide (ATH) system. If you need to use a high amount of additives, you can match this product with VOK ®- Dispatch W9010 (1:1) is used.

Recommended use

Low profile and Class A surface formula

Low shrinkage formula

Epoxy system

Pultrusion forming

Stable viscosity in BMC

Recommended dosage

1-2% dosage of additives (purchased form) is based on the amount of filler and used for wetting and dispersion.

0.5-2% of auxiliary dosage (purchased form) is based on resin quantity and used to stabilize viscosity in BMC.

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 W996 shall be added to the resin mixture before uniformly mixing and adding filler.

Adhesives and Sealants

Product characteristics and advantages General purpose, economical wetting and dispersing additives, used in adhesive and sealant applications. It is very effective in highly filled aluminum hydroxide (ATH) system. The additive can improve the wettability and dispersion of mineral filler. The viscosity of the system is lower, thus increasing the filler content. If you need to use a high amount of additives, you can match this product with VOK ®- Dispatch W9010 (1:1) is used.

Recommended use

The additive is especially recommended for epoxy resin type adhesives.

Recommended dosage

1-2% of the amount of additives (purchased form) is based on the amount of 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.
