  • USE OF A COMPOSITION AS A BINDER COMPONENT FOR PRODUCING FEEDER ELEMENTS ACCORDING TO THE COLD BOX PROCESS, CORRESPONDING METHOD, AND FEEDER ELEMENTS
    Publication number: 20190047041
    Abstract: A description is given of a use of a composition comprising an ortho-fused phenolic resole in an amount of up to 60 wt %; as first solvent for the ortho-fused phenolic resole, one or more compounds selected from the group consisting of alkyl silicates, alkyl silicate oligomers and mixtures thereof, the total amount of these compounds being greater than 30 wt %; optionally one or more further solvents for the ortho-fused phenolic resole; optionally one or more further additives; the weight percentages being based on the total amount of the composition, as a binder component for producing feeder elements by the cold box process. A description is also given of the use of a two-component binder system for producing feeder elements by the cold box process, and of a method for producing a feeder element for the foundry industry, and also of a feeder element.

  • Cold-box binding agent systems and mixtures for use as additives for such binding agent systems
    Patent number: 9238264
    Abstract: A description is provided of a mixture which is preparable by allowing the reaction of a premixture of (av), methanesulfonic acid (bv), one or more esters of one or more phosphorous-oxygen acids and (cv) one or more silanes. The invention also concerns the use of said mixtures as additives for the polyisocyanate component of a two-component binding agent system for preparation of a polyurethane resin. The invention further concerns a solution containing polyisocyanate for use as a component of a molding material binding agent system, and the use of a solution containing polyisocyanate as the polyisocyanate component of a two-component binding agent system for preparation of a polyurethane resin and corresponding two-component binding agent systems for preparation of a polyurethane resin.
