Codyeco is introducing an innovative white pigment into the market of leather finishing called Basetone White Ti-Free. This white pigment is formulated with insoluble inorganic and non-harmful substance and 100% free of TiO2.
“The technology of Basetone White Ti-Free allows to reach very high covering power and excellent physical fastness properties without losing refraction-index with a consequent great white intensity” Codyeco experts explain. Due to its special formulation, this pigment perfectly fits when used on metal free white leather following ISO specification 15115: 2019.
Ready for market release
The production trials have shown very positive results and Codyeco is now ready to release Basetone White Ti-Free into the market. “Our mission, and that of our mother company Smit & Zoon, is to create a socially and environmentally sustainable leather value chain by 2025. With Basetone White Ti-Free we are taking an important step towards making this mission reality,” says Fabrizio Ugolini, Global Product Manager Finishing Division of Codyeco.
Titanium is the ninth element in terms of relative abundance. Titanium dioxide occurs in nature in five different crystalline forms; the most important are rutile and anatase. Titanium dioxide is industrially purified through a chlorine and carbon coke process. Titanium is widely used as (e.g.) catalizer, UV filter in sun cream, food dyes (E-171), biotechnologies and medical use (prostheses) and white pigments because of its brightness and high refractive index.
Due to recent constraints on the use of Titanium Dioxide due to possible toxicology, as expressed by ECHA (European Chemical Agency), Codyeco has been working on this innovation to bring a new generation of white pigment free of TiO2 into the market.
