Epoxy polyester phenolic silicon steel sheet varnish (133A) is made from epoxy resin, heat-resistant polyester, butyl ether cresol resin, xylene and etc..

It has advantages of rapid curing, good adhesion and dielectric performances. What’s more, the film is hard and water resistant.

It is widely used for the insulation between the silicon steel sheets of large electrical machines.

The temperature classification of this kind of product is F, which suggests that the temperature that it can withstand is at most 155℃.

It has been recognized to enterprise standard.
