Special Tips

VOK ?- FL 3455 is used to improve the substrate wetting and leveling of the system. It has the characteristics of low foam stability, hydrolysis resistance and fluorine free.

Application field

Coating industry

Features and Benefits

VOK ?- FL 3455 can strongly reduce the dynamic and static surface tension of the system, thereby improving the wetting ability and leveling property of the substrate. VOK ?- FL 3455 can help wet very difficult substrates such as porous, rough wood.

VOK ?- FL 3455 is unstable, does not affect recoating and has no effect on surface smoothness. It can improve the "frame effect" and "fish eye" problems of the paint. Because of its excellent compatibility with many systems, including the formulation with low content of cosolvent, VOK ?- FL 3455 is ideal for modern paint formulations.

Recommended use

Wood Coatings 

Industrial coatings

Anticorrosive coating

Architectural coatings

Leather coating

Recommended dosage

0.1-1.0% of 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

The additive can be added at any stage of production, including post addition.

Adhesives and Sealants

Features and advantages

VOK ?- FL 3455 strongly reduces the surface tension in the water-based adhesive system, so it can improve the wetting on the substrate surface that is particularly difficult to wet, thereby improving the adhesion. VOK ?- FL 3455 Unstable foam.

Recommended

VOK ?- FL 3455 is particularly suitable for adhesives for wood and packaging materials.

Recommended dosage

0.05-0.5% of 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

It can be added at any stage of production, but we recommend adding it later.

Printing ink

Features and advantages

VOK ?- FL 3455 can improve the wetting of the substrate in 100% solid UV curable flexographic ink and water-based ink, and also can improve the leveling of the system, especially in UV varnish.

Recommended dosage

0.2-1.0% of 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.
