Ingot bonding

Typical application

For Ingot bonding technology, especially in solar industry, PROTAVIC provides easy removable adhesives for temporarily bonding. The process of slicing the ingot involves adhering two or more ingot blocks onto a beam (in glass for instance) and then mounting the joined blocks onto the wire sawing equipment (work plate).
Afterwards, the wafers can be debonded without leaving any residue, in baths of hot water.
