Properties and Application:
Prepreg DMD is made by the process of pre-curing the modified F-class DMD with Impregnation of Hi-temp resistant B-stage Epoxy resin by baking, with long shelf life at room temp, low pre-curing temp & time, excellent electrical insulation, bonding and heat-resistant properties.

Its thermal Glass is F, widely used for liner insulation of copper foil (aluminum foil)-wrapped Low voltage coils in dry-type transformer and slot insulation & phase insulation in B~F class Motor & electrical appliances.
