Product Description

1.Description
JF310F6 solvent-free submerging resin is composed of epoxy resin, heat resistant polyester, curing agent, active diluents, evocating agent, promoting agent, etc.The product shall be stored in single component. JF310F6 solvent-free submerging resin is a low-viscosity liquid under room temperature, whose
storage period is 6 months. The product cures under 150 ° C  with little volatilization during curing. The condensate of the varnish shows excellent electric and mechanical performance as well as dust-proof, moisture proof and mold proof. Compared with similar properties,
JF310F6 solvent-free submerging resin is featured in the excellent performance .
Application of this varnish is found in varnish submerging treatment for coils in various types of Grade B, and Grade F low-voltage middle/small  transformers, motors.
