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.
