New Choice for Defoamer in Photocuring Systems: Localized High-Performance Polymer Solution, Say Goodbye to Bubble Defects

Currently, many coatings and ink systems prefer polymer-based strong defoamers, especially for systems prone to producing microbubbles and those with high recoating requirements, such as 100% UV curing systems.

BYK Chemie has successfully developed a localized new defoamer to meet the requirements of the above-mentioned coating systems. Its advantages are as follows:

Has a strong defoaming effect

Does not affect or hardly affects shrinkage cavities.

Does not affect recoating.

Does not affect the transparency of the final coating.

Solvent-free

Product Features

Defoaming effect inside the tank

Test system: 100% solvent-free UV system, silicone-based surface additive: 0.1%, defoamer: 0.1%

The impact of crater formation and transparency in high gloss varnish systems.

^* 1 is best, 5 is worst

Testing system:100% solvent-free UV system silicone, surface additive: 0.1%, defoamer: 0.1%, film thickness: 30 microns, application method: frame applicator.

Advantages Summary

■Solvent-free, silicone-free polymer defoamer

■Compatibility wide

■It does not affect gloss and transparency.

■Specifically suitable for 100% photo-curing systems

■ Recommend high solids, solvent-free polyurethane systems.

Scope of Application

A solvent-free, non-silicone polymer defoamer suitable for radiation curing, solvent-free, high solid content, and solvent-based systems, especially suitable for 100% UV curing systems.

Recommended dosage

0.1 - 1.0% additive dosage (as purchased) based on the total paint formulation.
