Abstract
Abstract A composition comprising a liquid polymerizable resin and an alloy of iron and silicon, known as ferrosilicon, for use as a metal repair or reclamation material. The invention also includes a two-component pack including the liquid polymerizable resin as one component and a catalyst or hardener therefor as the other component, ferrosilicon being present in one or both components.
