Why Are KEIM Mineral-Based Sol-Silicate Paints Different?

Silicate Paint is a high-performance paint formed by the precise combination of liquid water glass (potassium silicate), inorganic color pigments, and mineral-based fillers. Unlike organic synthetic paints that merely sit on the surface, silicate paints deeply penetrate and chemically bond with the mineral substrate.

Unmatched Longevity & Protection

While organic synthetic paints simply form a removable film layer, KEIM silicate paints chemically integrate to become an inseparable part of the surface.

The Town Hall in Schwyz, Switzerland, painted with KEIM silicate paints in 1891, still retains its original vibrant appearance today—proving over 130 years of weather resistance.

What Are the Advantages of KEIM Silicate Paints?

KEIM Natural Raw Materials
Natural Raw Materials: Pure potassium silicate binder, naturally sourced mineral fillers, and inorganic paint pigments.
Silicification Penetration
Silicification: The liquid binder penetrates mineral pores and forms an insoluble, permanent chemical bond.

1. Silicification (Chemical Bonding)

In KEIM silicate systems, the liquid potassium silicate binder deeply penetrates plaster, natural stone, or concrete. This chemical reaction creates an insoluble mineral bond called silicification.

2. Extremely Long-Lasting Durability

KEIM silicate paints do not flake, peel, or blister. The binder is completely immune to UV radiation damage, acid rain, atmospheric industrial gases, and severe weather exposure.

3. Perfect Moisture Balance & Vapor Permeability

Extremely high water vapor permeability allows moisture inside the wall to escape freely outwards. Preventing moisture entrapment eliminates frost damage and structural deterioration.

4. Anti-Static Cleanliness

Unlike thermoplastic resin or silicone paints that attract airborne dirt when heated or charged by wind friction, KEIM silicate paints are anti-static and remain clean over decades.

5. Vibrant Matte Aesthetics & Luminosity

Because potassium water glass is completely transparent, ambient light hits the mineral pigments unhindered. This produces an exceptionally radiant, naturally impressive matte finish.

6. Health, Safety & Zero VOC

Completely free of Volatile Organic Compounds (VOC), solvent-free, non-toxic, odorless, mold-inhibiting, and non-flammable (releases zero toxic gas in case of fire).

KEIM High Luminosity
Unimpaired Light Refraction: Transparent mineral binder allows unhindered light reflection from pure mineral pigments.

Color Fastness: No Fading Over Decades

Summary: Why KEIM Silicate Paints Lead the World

Radiant, non-fading color tones and clean exterior facades over decades can only be achieved when coating materials fulfill strict physical and chemical criteria:

  • UV and acid-resistant mineral pigments
  • UV and weather-resistant potassium silicate binder
  • Anti-static and non-thermoplastic surface
  • Maximum vapor breathability & ideal drying
  • Transparent mineral matrix for optical brilliance
  • Ecological, non-flammable & 0% VOC formulation
