Abstract

The invention relates to a coating composition for coating electrically conductive wires. The coating composition comprising 0.1 to 60 wt% of reactive particles, based on an element-oxygen network and further having reactive functional groups chemically bound to the surface of the element-oxygen network. At least one of the reactive functional groups is an isocyanate group that is bound to the reactive particle via a carbamate group. The coating composition can further contain one or more conventional binders and other additives.

Description

technical field

[0001] The present invention relates to coating compositions which provide highly increased thermal and mechanical resistance of coatings for use on electrically conductive wires. Background technique

[0002] Three-phase AC motors, such as inverter-controlled motors or high-voltage asynchronous motors, need to be wrapped with wire rods, which should meet strict requirements in terms of heat resistance and mechanical properties, mainly the bending strength of the insulation layer, so as to be able to withstand High voltage load and pulse-shaped voltage load without damage. Furthermore, especially heat resistance is very important for motors operating at high temperatures. Another requirement for wire wrapping of electrical equipment is the partial discharge resistance of the wire coating.

[0003] According to WO96 / 41909 a coating composition is disclosed comprising a binder and a particulate material, wherein the particulate material may be a metal oxide s...
