Title: COLD-BOX BINDER SYSTEMS AND MIXTURES FOR USAGE AS ADDITIVES FOR SUCH BINDER SYSTEMS
Abstract:
A mixture is described which can be produced by causing a reaction of a precursor mixture of (av) methanesulfonic acid (bv) one or more esters of one or more phosphorus oxoacids and (cv) one or more silanes. The invention additionally relates to the usage of said mixtures as additives for the polyisocyanate component of a two-component binder system for producing a polyurethane resin. The invention further relates to a solution containing polyisocyanate for usage as a component of a moulding material binder system, to the usage of a solution containing polyisocyanate as the polyisocyanate component of a two-component binder system for producing a polyurethane resin and to corresponding two-component binder systems for producing a polyurethane resin.
