2. 1. 1. Limit for organic components in mineral paints

The term “mineral paints” refers to silicate and lime paints. Pure silicate paints consist only of potassium water glass, inorganic pigments and fillers. They are applied as two-component systems. Single-component silicate paints are called emulsion silicate paints. Their organic components must not exceed 5% by weight. For lime paints, no limit for plastic contents has been defined.

Mineral paints have several advantages:

They primarily consist of mineral raw materials and thus no fungicides are needed even when applied in high-humidity rooms.
They do not inhibit water vapour diffusion.
They can easily be disposed of.
Silicate paints silicify with the mineral substrate. In contrast to emulsion paints, which form a film on the substrate, silicate paints react chemically with the mineral substrate.

The higher their content of organic components, the more desirable properties are lost.

The organic components of emulsion silicate paints and emulsion lime paints must not exceed 5% by weight.
