Clariant accelerates the move to waterborne coatings with sustainable additives solutions
SWITZERLAND -- Specialty chemical company Clariant has introduced a new line of environment- and performance-focused waterborne coatings for exterior protective applications. The Hostavin line of light stabilizer solutions represents a new option for the coatings industry, where solventborne systems have been the standard.
Clariant’s Hostavin, a non-migrating high molecular weight HALS, optimize light stabilization for clear and pigmented waterborne coatings. As the market is replacing its long-term emphasis on solvents with a step-by-step transition towards waterborne systems, Clariant now offers the coatings industry opportunities to fill the performance gap, especially in premium segments such as exterior wood protective coatings, as well as high-end industrial coatings.
The new solutions represent the first high-loaded waterborne dispersion of a triazine class UV absorber, the latest generation of UV absorbers, and bring significant improvement in UV protection for waterborne systems. It offers high thermal stability and durability for prolonged service life, displaying high extinction in the protection of thin layers. It does not contain any VOC compounds and its compatibility with binders makes it easy to incorporate and handle for paint producers.
The addition of Hostavin in the formulation further enhances performance benefits, thanks to its higher thermal stability and migration resistance. Its improved toxicological profile, compared with traditional HALS, makes it free of any hazard labeling.
