9000 - 17000 Viscosity Light Yellow Transparent Liquid Casting Epoxy Resin With CW - 6225

Delivery Time:7 days
Certification:ISO9001,ISO14001,GB/T28001

Description:

CW-6225 APG type casting resin system is suitable for production of electrically insulators for medium and high voltage, such as post-type insulators, supports, switcher, bushing, current and voltage transformers (dry type) by means of moulding or APG process. It has very high resistance to mechanical, electrical stresses and thermal shock. It has excellent long-term behaviour in relation to breakdown stress.
