Recommended dosage

0.2-0.8% of auxiliary dosage (form of supply) is based on the general formula.

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 defoaming effect, defoamer should be added to the abrasive. If it is added at a later stage, a sufficiently high shear force must be applied to ensure good dispersion and thus prevent shrinkage.

Room temperature curing plastic system

Product features and advantages

VOK ®- DF A530 is an efficient defoaming agent, which can reduce the formation of foam in the production and processing of epoxy resin system to obtain a bubble free surface.

Recommended dosage

0.5-2% auxiliary dosage (supply form) is based on the general formula.

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

Adding method and processing guidance

Stir in the resin before adding other components. The additive can also be added to the finished product.

Pultrusion process of plastic system

Product features and advantages

Prevent air from mixing during production and application (pultrusion process). Especially recommended for epoxy resin systems.

Recommended dosage

0.5-2% auxiliary dosage (supply form) is based on resin and curing agent.

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

Adding method and processing guidance

Stir in the resin before adding other components.
