Oil synthetic silicon steel sheet varnish (1611) is mainly made from Tung oil, resinate, and 200# petroleum solvent.

The paint film has the following characteristics: hardness, oil resistance, and better dielectric performance.

Oil synthetic silicon steel sheet varnish (1611) is widely used for the insulation between the silicon steel sheets.

The temperature classification of this kind of product is A, which suggests the temperature that it can withstand is at most 105℃.

It has been recognized to JB/T 904-1999.
