Silicate compounds are not only important basic constituents of minerals and rocks; for millions of years, they have also acted as binders in sedimentary rocks (e.g. as silicate-bound sandstone).

Silicate binders were known as early as antiquity. About 150 years ago, they began to be used as binders in wall paints.
Today, modern, ecofriendly, silicate-based coating systems are an indispensable tool for professionals in the building paints and plasters industry. They are able to meet the high requirements of architects, artisans and building owners.
The Betolin System by Wöllner has been designed for this kind of coating systems and employs for high quality silicate binders and formulation additives.

Resulting silicate paints and plasters have the following significant advantages:

- Ready-to-use, storable formulas
- Good application properties on most substrates
- Open-pored coating, hence good steam permeability
- Good color stability
- Harmonious, matte surface appearance
- Low tendency to soil, self-cleaning properties
- High durability, hence very efficient
- No preservation required to ensure storability 
- Silicate binders do not cause allergies
- Suitable for indoor and outdoor applications in new and old buildings
- Harmless to the environment
