Silicone resin emulsion paint was developed in WACKER’s laboratories forty years ago, and a patent application was filed by the three researchers Siegfried Nitzsche, Ewald Pirson and Michael Roth. This made WACKER the first company to introduce silicones for masonry protection, and the global market leader in this field. Incidentally, the paint was initially called “Munich paint.”

As the most advanced modern facade coating systems, silicone resin emulsion paints enjoy widespread acceptance in Europe, and they are also being used increasingly to treat construction objects in the USA, Singapore and Japan. Almost every manufacturer of exterior paints includes these products in its range.

“The invention relates to coating materials based on aqueous dispersions of organopolysiloxanes and an organic resin content, said organic content, however, not exceeding the organopolysiloxane content. The coating materials according to the invention provide washable, chalking-resistant coatings, which have high water repellency and weathering resistance and outstanding permeability to air and water vapor.”
