Silicate paints are based on natural raw materials.

Basic Principles

Waterglass – Silicate paint binder …

The most important thing that determines the quality of a paint is the binder, which combines all the different ingredients and ensures that the paint adheres to the substrate. There is a difference between inorganic and organic (mineral) binders.

Inorganic binders are obtained from mineral raw materials. The most resistant mineral paint binder is glass water (potassium silicate).

Silicate paints react chemically with the surface on which they are applied.

Silicate paints react chemically with the surface they are applied to.

In silicate systems, the binder glass water interacts with the substrate on which it is applied, forming an insoluble and permanent bond with a chemical process called silicification. Looking at the enlarged plaster section, the colored KEIM binder penetrates the surface and forms an insoluble bond. This bond is one of the most important factors that ensure the unique durability of KEIM silicate paints.

Organic binders such as synthetic resin emulsion paints or silicone resin emulsions are based on hydrocarbon chemistry (petrochemistry) and adhere only to the surface by a physical adhesive bonding process.

Synthetic resin emulsion paints work only on the adhesion principle.
