Typical Physicochemical Data

The data given in this data page are only typical values, not technical indicators of the product.

Density (20 ° C): 1.01 g/ml

Storage and transportation

The product may be layered. Mix well before use. The additive has good low temperature stability, but it is recommended to store at 10-25 ° C for optimal operation.

Application field

Coating industry

Product features and advantages

VOK ®- DF 012, as a defoamer, is specially recommended for the production and construction of latex paint and plaster with a pigment volume concentration (PVC) of 30-85. The additive contains no organic silicon and mineral oil, and is particularly suitable for VOC free systems. Even in very low dosage, the effect is still ideal. The additive is stable to acid and base, and can be used for systems with PH values in the range of 3-12. VOK ®- DF 012 There may be turbidity and particle precipitation in the transparent paint.

Recommended use

Architectural coatings

Wood furniture paint

Leather finishing agent

Protective paint system

Recommended dosage

0.05-0.5% additive dosage (purchased form) is based on the general formula.

The above recommended dosage is for reference only, and the appropriate dosage shall be determined through a series of tests. VOC free (<1500 ppm) Alkylphenol ethoxide free

Adding method and processing guidance

The additive can be added at any stage of production. However, it must be uniformly dispersed under a sufficiently high shear force.

Printing ink and varnish

Product features and advantages

VOK ®- DF 012 is especially suitable for use as defoamer of water-based printing ink. The additive does not contain organic silicon and mineral oil, and the effect is still ideal at very low dosage. VOK ®- DF 012 may be turbid and precipitated in the varnish.

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 only, and the appropriate dosage shall be determined through a series of tests.

Adding method and processing guidance

The additive can be added at any stage of production. However, it must be uniformly dispersed under a sufficiently high shear force.

Adhesives and Sealants

Product features and advantages

VOK ®- DF 012 is an efficient defoamer suitable for all dispersion adhesives at present, which can inhibit the generation of foam in the preparation and application of adhesives. Especially recommended for polyacrylate dispersion adhesives. The additive contains no organic silicon and mineral oil, and is especially recommended for systems without volatile organic compounds (VOC). In the case of low dosage, it also shows good results. It is stable to acid and base, and can be used for systems with PH value in the range of 3-12.
