Light Refraction

Illuminates dark areas and reduces heat absorption

KEIM Silicate painted surface have a beautiful mineral matte finish, that refracts light in all directions. Conventional paints provide a smooth surface that bounces light back in angles related to the light source and can cause glare, even in low luster finishes.

Seen at left below, silicate finishes and stains have a micro-crystalline surface structure, which refracts light and heat, in all directions. These finishes have an inherent and unique aesthetic, and even in low-level light, tend to appear more luminous. This refraction eliminates dark corners in low light areas such as parking garages or transit tunnels.

The non-glare characteristic of these finishes also make them ideal for public spaces and classrooms, where artificial light glare has been linked to poorer learning practices. They are also ideal for art galleries and museums where exhibits and art are frequently “spot lighted” and glare can be a distraction.

In hot climates this refraction property reduces the thermal stress on the structure and can reduce the amount of cracking of the surfaces.

Benefits at a glance...

  • Mineral matte finish will never cause harsh glare, no matter the light source
  • Matte finishes in any color, even black
  • More natural appearance in artificial light
  • Reduces thermal stress from heat absorption of painted surfaces
  • Can reduce surface damage from thermal shock by helping to mitigate expansion and contraction
  • Silicate will not lose adhesion with thermal changes
  • Silicate finishes will not soften when exposed to direct sunlight or ambient heat

Radiant Light — How It Works

Silicate finishes diffuse glare through light refraction: spreading light in all directions for soft, even illumination.

Notice the micro-crystalline matrix and how it “spreads” the light and heat in all directions and is physically unaffected by light or heat.

Ordinary paint produces glare by bouncing light at an angle relative to the source.
 

The smooth surface of acrylics, bounce light back, at a direct angle from the light source and because they are thermo-plastic, become soft when exposed to direct sunlight and ambient heat.
