BYK-1790

MITM02196
ITM03920, ITM03921

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.

Applications

Coatings and Printing Inks

BYK-1790 is silicon-free and is recommended for solvent-free, radiation-curing (UV and ESH) coating systems (pigmented and unpigmented), printing inks and overprint varnishes. The high efficiency of the defoamer is not impacted by pigments, fillers, wax additives or matting agents.

Adhesives & Sealants

BYK-1790 is silicon-free and is recommended for solvent-free, radiation-curing (UV and ESH) adhesives (pigmented and unpigmented) as well as for reactive polyurethane hot melt adhesives. It has no negative effect on the adhesive properties of the adhesives. In radiation curing formulations, BYK-1790 is ideal for universal use in acrylate based binders. It prevents foaming in the manufacture of reactive polyurethane hot melt adhesives even at high viscosity. Significantly shorter evacuation times lead to an increase in the efficiency of production due to the additive.
