| BASF expands range of binders for wood coatings BASF is launching with immediate effect a series of new products and applications for outdoor wood coatings in the acrylic dispersions segment: Acronal DS 6276X and Acronal DS 6277X ensure superior weather durability and advanced blocking resistance of the coatings they are used in. In addition, they defoam well and can be easily and cost-effectively formulated using conventional rheology modifiers. BASF has considerably expanded the application spectrum of Acronal A 508, AQAGloss and COL.9, which are already on the market. Acronal DS 6276X is an extremely fine-sized, self-crosslinking pure acrylate dispersion for high-quality decorative and industrial wood window and door coatings. The new dispersion leads to excellent blocking and water resistance and thus superior durability of the coating it is used in. Additionally, the binder is wet transparent leading to excellent in can clarity of stains. Acronal DS 6276X especially meets the requirements of the southern European market. Acronal DS 6277X is softer and extremely flexible. Nevertheless it displays good blocking strength. The binder protects pigmented, decorative wood coatings – often used on wooden claddings in Northern Europe – against water penetration. Further to that, it acts as an elastifying component in harder coatings, transparent and pigmented alike. In this way Acronal DS 6277X helps to prevent weathering-related cracks in the coating. Acronal A 508 is a binder for primers and impregnations. The product offers a number of unique advantages. According to Dr. Arno Tuchbreiter, from product development: "Primers formulated with Acronal A 508 lead to pronounced grain enhancement. They improve adhesion induced by easy penetration of the very fine and colloidal stable dispersion particles into the wood. Acronal A 508 is also highly compatible with fungicides like IPBC." AQAGloss, originally developed for high-gloss paints, can now also be used for wood coatings showing excellent long term weathering results. In the field of water-based coating systems, AQAGloss is an innovation that offers an alternative to conventional solvent-based architectural coatings. AQAGloss also introduces new possibilities for processing: it forms a crystal-clear, tack-free film at room temperature, is extremely easy to apply and has a long open time. Other advantages for users: AQAGloss ensures haze-free, high-gloss surfaces previously only associated with solvent-based alkyd resin coatings. The COL.9 nanotechnology is now also implemented into BASF's solutions for wood coatings. New binders based on the COL.9 nanotechnology ensure dirt and blocking resistant wood coatings with excellent water vapor permeability. The first prototype for industrial topcoats for window coatings with outstanding weathering stability will be introduced in 2009. COL.9 is already being successfully used as a binder for dirt resistant and color tone stable architectural coatings. write your comments about the article :: © 2008 Construction News :: home page |
