Technical Data Sheet

 High solid primer defoamer BYK-1790

BYK-1790 Defoamer is a silicone-free, polymer based defoamer for solvent-free, radiation-curing wood and industrial coatings, printing inks and adhesives. Suitable for pigmented and unpigmented coating systems. The high efficiency of the defoamer is not impacted by pigmnets, fillers,wax additives or matting agents,

Typical Physical Data

Application : BYK-1790 is suitable for coloring and varnish systems, and also has excellent defoaming properties in systems containing pigments, fillers, wax auxiliaries and matterers. Radiation curing systems, solvent-free systems for industrial coatings, printing inks and paper coatings.

Usage: In order to obtain sufficient defoaming effect, it is recommended to add it before grinding. If added later, mix under sufficiently high shear to ensure defoaming.

Features and advantages: BYK-1790 has excellent defoaming and anti-foaming effects, which can inhibit and eliminate the bubbles generated during the production, canning and construction of coatings, especially for the bubbles generated by the reaction of two-component coatings and high zinc stearate The defoaming effect in the formula is remarkable. Since BYK-1790 has an incomparable defoaming effect with other types of defoamer, it is very effective in primers.

Packaging: 25kg /drum. The product is completely unused before use, and the inner and outer covers must be tightly closed after use.

Storage: Keep away from heat, fire and light.

Note: Please carefully evaluate the effect on compatibility and shrinkage crater before use.
