Timeless Brilliance
Deep red or fluorescent orange: bright facade colors are in fashion. To ensure they lose none of their radiance even after many years, WACKER has developed a new binder: PRIMIS ® AF 1000.
There are fundamentally two types of pigments available for coloring architectural paints. Both are available in natural and artificial versions, and each has its specific pros and cons.
Heroes of Resistance: Inorganic Pigments
Most inorganic pigments are heat and light resistant and do not chemically react with oxygen in the air. That is why they are used for painting on porcelain. However, they are only available in a limited range of colors. In the red range, only a few, rather subdued, shades are available. The best known natural inorganic pigments include chalk, ocher, umber and graphite. Traces of these pigments have survived since prehistoric times.
A Variety of Hues: Organic Pigments
Organic pigments are generally much more chemically complex. This allows a wide range of shades to be obtained, including many with high brilliance and color intensity. Though they are more susceptible to light, oxygen and heat. In their natural form, organic pigments are obtained from plants and animals. Familiar examples of colorants and the pigments obtained from them are carmine (extracted from cochineal bugs), sepia (from the ink of the cuttlefish) and indigo (from the leaves of the indigo bush). Artificial indigo is still used to dye most jeans.
PRIMIS ® AF 1000 Bonds
Architectural paints are particularly exposed to UV light, temperature changes and weather and in the past have therefore usually been colored with the more resistant inorganic pigments. The new PRIMIS ® AF 1000 dispersions make paints so highly light resistant that even organic pigments retain their radiance over years. A wider range of colors is thus possible.
PRIMIS ® AF 1000 is subjected to extensive testing both in the WACKER labs and at WACKER’s outdoor weathering station.
The Best of Both Worlds: PRIMIS ® AF 1000
PRIMIS ® AF 1000 contains an inorganic core in an acrylate-based aqueous polymer dispersion. This combination leads to a range of advantages
