Solution of Polyorganosiloxane Resin Modified with Polyester in Xylene
Trade Name: Siliconorganic varnish type KO-916K
H.S. Code 3208 90 910 0
¹ UN: 1263
Main applications:
- Brand A - for impregnation of electrical machines and apparatus windings with heat resistance of class H;
- Brand B - for protection and decoration of metal surfaces.
Features:
- effective impregnation ability due to min viscosity and low surface tension;
- varnish film fast drying;
- effective adhesion to metal surfaces;
- cements well separate turns and layers of winding and isolation;
- forms glossy, rigid and firm film;
- high thermal conductivity;
- harmless to copper and isolation of enameled wires;
- moisture and water repellant;
- preserves thermoelasticity while long heating of isolation in the process of electric machines running;
- heat resistant (class H);
- dielectric;
- adhesive;
- dielectric property and corona resistance practically are not influenced by high temperature and moisture.
