The requirements in terms of outdoor durability in the joinery market have increased significantly over the last years. High performance waterborne dispersions have been developed for this purpose. BASF continues to develop products which can meet these stringent performance requirements. The first waterborne UVA/HALS blend using proprietary neat technology has been recently launched. This new product fulfills these high-end requirements as it is composed of a high performance UV absorber and a non-interacting HALS, making it compatible for all resin types, especially sensitive resins. This novel blend offers a superior photo-permanence and it not only improves the durability of the wood but also the performance of the wood coatings in terms of superior color and gloss retention. The neat technology allows an additional step forward in the reduction of VOCs. The new product is solvent-free and does not require any co-solvent for its addition into the formulation.
