CX200N-MP

Description

Introduction

CX200N- MP insulating varnish is fast curing, heat resistant class N (2ooc), compliant with EU ROHS, REACH, halogen free, suitable for the immersion of small to large motor stator coils with high heat resistance requirements (immersion, drop down).

1、Product characteristics

Modified unsaturated polycool resin, reactive diluent, initiator compound

Fast curing, fast internal drying

High adhesion between enamelled wires, reduces transformer noise

No solvent evaporation, reducing environmental pollution

Heat resistance class: N (2ooc)

Compliant with EU ROHS, REACH, halogen free

2、Applications

For the impregnation of small to large motor stator coils with high heat resistance requirements (immersion, drip down).
