Buhler has introduced Oxylink, a new functional additive for waterborne paints and varnishes designed to improve the characteristics of coatings. A widely applicable additive based on nanoparticle technology, Oxylink is particularly suitable for one-component formulations and it facilitates compliance with future environmental requirements. Oxylink is a formulated additive that improves MEK rub resistance, blocking and humidity resistance and it reduces drying time. Other important parameters such as gloss are not affected. Oxylink 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. The additive may be used for clear as well as pigmented formulations. Oxylink is available in three standard categories—Oxylink 3101, 3102 and 3103.
