KEIM’S SILICATE PRINCIPLE: UNEQUALLED DURABILITY DURABILITY AS A MATTER OF PRINCIPLE A facade coating should last for at least 20 years – in visual and in functional terms. This won’t be a big challenge for mineral paints as they easily last twice that long thanks to their silicate structure. Silicate technology is the silicification of the binder with the mineral substrate. The liquid binder (potassium water glass) in the paint forms an insoluble, crystalline bond with the substrate (render, natural stone, concrete, etc.) due to a chemical reaction. This type of bonding is the crucial factor for the unequalled longevity of KEIM’s silicate paints. District recruiting office in Potsdam (left), painted in 1992 with KEIM silicate paint (colour shade 9071). Right: This part was coated with an organically pigmented paint from a competitor in the same colour shade, but clearly shows a colour change! The binding agent potassium water glass silicifies with the substrate. Lightfast! 21-year-old coating.
