Abstract
PURPOSE: To prevent the occurrence of voids and obtain long period preservation stability by using prescribed epoxy resin varnish. including fluorin-containing surface active agent and silicon-containing defoaming agent.
CONSTITUTION: Feeding mica leaf 1, laminating with glass cloth 2, and transferring to the guide roll 3 and backing roll 4. On the other hand varnish with prescribed composition mentioned below transfers from a vanish pan 7 between metering roll 5 and coating roll 6 to the felt roll 8, on this place the varnish permeates into the mica leaf 1 through glass cloth 2. Above mentioned varnish is a composition with a viscosity of 300 to 6000 cst at 25°C and 60 to 95% of non- volatile component including fluorin-containing surface active agent of 1 to 0.03% and silicon-containing defoaming agent of 0.05 to 0.2%. Then varnish contained tape is dryed 9 and wound 10.
