20140102657 | REFRACTORY COATING FOR PRODUCING MOLD COATINGS - A refractory coating for producing mold coatings by application to inorganically or organically-bound molding materials in lost molds or to cores for iron and steel casting is disclosed. The refractory coating can have a proportion by weight of 0.001% or more and less than 1% of inorganic hollow bodies, which partially or fully consist of crystalline material and have a softening point of 1000° C. or higher. | 04-17-2014 |
20130292083 | SULFONIC ACID-CONTAINING BINDING AGENT FOR MOULDING MIXES FOR THE PREPARATION OF MOULDS AND CORES - A polyisocyanate component for a moulding material binding agent system is described containing at feast one sulfonic acid in a solution of at least one polyisocyanate, containing at least two NCO-groups in the molecule. | 11-07-2013 |
20130225718 | COLD-BOX BINDING AGENT SYSTEMS AND MIXTURES FOR USE AS ADDITIVES FOR SUCH BINDING AGENT SYSTEMS - 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. | 08-29-2013 |
20120126092 | RELEASE AGENT FOR PRODUCING MOLD COATINGS - The present invention relates to a refractory coating for producing mold coatings by application to inorganically or organically-bound molding materials in lost molds or to cores for iron and steel casting, wherein the ready-to-use refractory coating has proportion by weight of 0.001% or more and less than 1% of inorganic hollow bodies, which partially or fully consist of crystalline material and have a softening point of 1000° C. or higher. | 05-24-2012 |
20110275758 | MODIFIED PHENOLIC RESINS - The present invention relates to modified phenolic resins which contain silicic acid ester units. The modified phenolic resins may, for example, be used as components of a foundry binder system. The invention also relates to a method for producing such modified phenolic resins and to two-component binder systems which contain these modified phenolic resins. The invention furthermore relates to methods for producing foundry molds and foundry cores which contain the modified phenolic resins, and to the foundry molds and foundry cores themselves. | 11-10-2011 |
20110269902 | MODIFIED PHENOLIC RESINS - The present invention relates to modified phenolic resins which contain silicic acid ester units. The modified phenolic resins may, for example, be used as components of a foundry binder system. The invention also relates to a method for producing such modified phenolic resins and to two-component binder systems which contain these modified phenolic resins. The invention furthermore relates to methods for producing foundry molds and foundry cores which contain the modified phenolic resins, and to the foundry molds and foundry cores themselves. | 11-03-2011 |
20100130653 | ALKALINE RESOL PHENOL-ALDEHYDE RESIN BINDER COMPOSITIONS - This invention relates to alkaline resol phenol-aldehyde binder compositions and their use in the production of articles of bonded particulate material such as foundry moulds, foundry cores, or feeders. | 05-27-2010 |
