Bühler launches additive for eco-friendly coatings

A new functional additive for waterborne paints and varnishes designed to improve the characteristics of coatings is on the market. Bühler has introduced "Oxylink", a widely applicable additive based on nanoparticle technology, particularly suitable for one-component formulations and it facilitates compliance with future environmental requirements. This additive improves MEK rub resistance, blocking and humidity resistance and it reduces drying time. Other important parameters such as gloss are not affected. It contains tailor-made nanoparticles that improve the coating by direct interaction with the resin. It is based on so-called dispersions of inorganic nanoparticles in water and requires a dosage of one percent.
