Abstract

An aqueous primer based on alkali-soluble acrylic resins and siliconates, especially suitable for strongly alkaline substrates, for example, asbestos cement articles, is provided. The primer is characterized by stability to storage and good compatibility with the substrate and with customary coating agents, and it brings about good water repellence, good stabilization of the substrate and a good binding between the substrate and the final coating.
