Product features and advantages

VOK ?- DF A501 is an efficient defoamer, which is used in almost all unsaturated polyester resins and processing technologies, and also recommended for epoxy resin systems.

Recommended use

Especially recommended for unsaturated polyester resin, epoxy resin, gel coat and casting system.

Recommended dosage

The dosage of 0.1-0.5% additives (purchased 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

The additive is added to the resin, and then other components are added. In some resins, defoamers may cause fogging of the finished product.
