Abstract
According to the invention, the composition contains an abrasive material (12.5-37.5 vol.-%), a metallic filler (30-60 vol.-%), a mineral binder (5-30 vol.-%) and the balance is an organic binder. The mineral binder is constituted by at least one substance from a group of salts whose melting temperature corresponds to the temperature range of polymerization of the organic binder.
Claims4
