Abstract
The present invention relates to a process for edge coating amorphous ribbon transformer cores comprising the steps of applying to at least one face exclusive of the distributed gap portion, a first porous material having a porosity sufficient to permit a liquid having a viscosty greater than about 100,000 cps to impregnate the porous material to produce a composite structure; and applying a bonding material having a viscosity of at least about 100,000 cps to the first porous material such that the bonding material substantially contacts the core. Coated cores having good magnetic properties are also disclosed.
