Korund is revolutionary insulation material, based on the recent developments in nanotechnology. The material is composed of high quality acrylic binder (an original mixture of catalysts and fixatives), ceramic ultrathin layer nanospheres filled with rarified air. In addition to the basic structure, there are special additives, that prevent corrosion on the metal surfaces and fungus in high humidity on concrete surfaces. This combination makes the material light and flexible. It has also high adhesion to the target surfaces. The material resembles the consistency of the ordinary paint. It is a white suspension, that can be applied to any surface. After drying flexible polymer coating is formed. It has unique insulating properties, compared to conventional insulators. It also provides corrosion protection. The material is highly effective for insulation of the facades, roofs, interior windows, slopes, concrete floors, piping, air conditioning systems,cooling systems, containers
