International. A new polymer-based, VOC- and silicone-free antifoaming technology has been developed that prevents foaming in aqueous systems.
Mineral oil-based defoamers are widely used – especially in applications where price is a key criterion. Negative side effects such as the tendency to separate, smell or environmental aspects that lack direct contact with food mean that the market is looking for affordable alternatives.
BYK developed a technology under reference 1640. The additive is a petroleum mineral and is therefore emission-free, odorless, silicone-free, and easy to incorporate. It is also suitable for some applications that come into direct contact with food and provides great versatility that makes it widely applicable: in architectural, protective, paper coatings, as well as in adhesives, construction chemicals and printing inks.
The product is not only effective in low doses. It is an antifoam that BYK will present at this year's European Coatings Show along with other additives for optimized processes.
