Silicone Resin Emulsion Paints

Silicone resin emulsion paints rank among the most modern facade coating systems. The binder in silicone resin emulsion paints comprises 50 % mineral-based silicone resin and 50 % polymer emulsion. On mineral building surfaces and in coatings, silicone resin binders from the SILRES BS^® series build up stable three-dimensional silicone resin networks. In the presence of moisture, catalytic condensation takes place, releasing alcohol. This network is the source of their water repellency and water-vapor permeability, and it is chemically bound to the mineral substrate.

Silicone resin emulsion paints thus bestow permanent water-repellency, which stems from the organic group on the silicone resin. The inorganic portion of the silicone resin “cements” the filler and the pigment together, creating permanently water-repellant capillaries and pores.

Thus, although the paint is open-pored and does not form a surface film, water is unable to penetrate and simply rolls off.
