1878 - the first generation: KEIM Purkristalat

Some 125 years ago, KEIM developed the first practical silicate paint. It consists of a powder component with mineral colouring pigments and extenders and a liquid component, the binder potassium water glass.
According to DIN 18363, 2.4.1, "silicate paints" are accordingly formulated in two components and contain no organic constituents. They can only be used on solid, absorbent, mineral renders.


1962 - the second Generation: KEIM Granital

1962 saw the introduction of the "silicate emulsion paint", the second generation silicate paint. Its advantage resides in its single-component formulation, which makes it considerably easier to handle and increases reliability of application. Silicate emulsion paints are also covered by a standard as an independent product category and, according to DIN 18 363, may contain at most 5% of organic constituents (dispersion and additives).

2002 - the third generation: KEIM Soldalit

In 2002, what is now the third generation of silicate paints revolutionised the exterior wall coatings market: the "sol-silicate paint" is based on an entirely new binder concept and so opens up whole new areas to silicate paints. The sol/silicate binder, a stabilised combination of silica sol and water glass, bonds with mineral substrates by silicification, but additionally develops strong adhesive forces which ensure a firm attachment to coatings based on organic resin binders, so allowing application to virtually any common substrate. Having an organic content of below 5%, the sol-silicate paint also satisfies the requirements of DIN 18363 for "silicate emulsion paints".
