Amorphous Core Insulation Impregnating Varnish
The amorphous core insulation impregnating varnish developed by Donghua New Materials, based on cycloaliphatic epoxy and multifunctional epoxy resins, strikes a careful balance between processability and functionality. Its matrix material gives the system outstanding processing characteristics: low viscosity, long shelf life, and low curing shrinkage. Meanwhile, thanks to its high purity and high crosslink density, the cured product not only offers excellent temperature and chemical resistance, but also forms an interfacial layer of high bond strength and highly reliable insulation against amorphous alloy, safeguarding the long-term operation of high-end equipment such as amorphous motors and transformers under harsh operating conditions.
