Application field

Coating industry

Product features and advantages

VOK®- DF 1786 has good effect in water-based system, especially suitable for airless and mixed construction. It can be used in both paint systems and varnish systems. It is particularly good at eliminating micro bubbles in the paint system, and does not affect the transparency and luster of the highlight system.

VOK®- DF 1786 also has good defoaming performance in waterborne UV system.

Recommended use

Architectural coatings

Wood and furniture coatings

Floor coating

Recommended dosage

0.2-1% auxiliary dosage (supply form) is based on the general formula, and can be added to 1.5% for special cases.

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

Adding method and processing guidance

The defoamer can be added at any stage of the production process. Sufficient shear force must be ensured.

Household, industrial and commercial cleaning and care products

Product features and advantages

VOK®- DF 1786 is a defoamer containing organic silicon, which is used for care products and cleaning agents. It has been proved that it has good defoaming effect both in the production process of the system and after construction.

Recommended dosage 0.1-0.3%

The amount of additives (form of supply) is based on the general formula.

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

Adding method and processing guidance

This additive is best added at the beginning of the formula, but it can also be added at any stage. When added to the low viscosity polishing agent, sufficient shear force must be guaranteed.

Adhesives and Sealants

Product features and advantages

VOK®- DF 1786 is a defoamer containing organic silicon, which is suitable for water-based adhesive system. This additive can inhibit the production of foam in the system production and construction process.

VOK®- DF 1786 not only has good defoaming performance, but also is easy to add and has good compatibility. This additive can be used in adhesive formulations that meet the ecological evaluation label.

Recommended dosage 0.1-1%

The amount of additives (form of supply) is based on the general formula.

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

Adding method and processing guidance

This additive can be added at any stage of the production process. Sufficient shear force must be ensured.
