Synthetic Finishing Varnishes and Glyptals.

Silicone oven varnish Class F – H

It is composed of synthetic resins modified with silicone resin in order to achieve high thermal resistance at temperatures above 155ºC.

It is impregnated and its preparation time is 3 to 4 hours at 140ºC – 160ºC. Under these conditions, an excellent cementing of bobbins and other insulating components are achieved.

As finishing varnish we recommend our two-component epoxy systems which come in grey, red and black.

Diluent: 180 – 1061

Specific Gravity (g/cm3) 1.01 +/- 0.02
Viscosity (Ford Cup 4) 90 – 120 seg.
Solids (%) 50 +/- 1
