NYACOL® offers three types of materials as transparent UV absorbers; cerium oxide, titanium oxide and zinc oxide. The materials all offer high transparency in the visible range and UV absorption spectra characteristic of the oxide type. The materials are used in coatings or as additives in films or fibers to control the UV absorption. These materials require careful formulation as they are all capable of generating free radicals which requires use of additives in the formulations or passivation of the inorganic surface.
We offer water based dispersions as the first option and then hydrocarbon based dispersions in some cases for formulating options.
