  • Patent number: 9080093
    Abstract: Antifreeze concentrate with corrosion protection which is suitable for coolants and heat transfer fluids and comprises freezing point-lowering liquids and also particular sulfur-comprising organic compounds, inorganic molybdate salts, inorganic phosphate salts and aliphatic, cycloaliphatic or aromatic monocarboxylic, dicarboxylic or tricarboxylic acids as corrosion inhibitors. Aqueous coolant compositions which are suitable for cooling an internal combustion engine whose cooling apparatus has been made of aluminum using a soldering process using a fluoroaluminate flux can be obtained therefrom.
    Type: Grant

  • Patent number: 9034209
    Abstract: Corrosion protection formulation comprising (A) from 0.01 to 5% by weight of alkylamine ethoxylates as surfactant component, (B) from 0.01 to 10% by weight of corrosion inhibitors, (C) from 0 to 0.3% by weight of thickeners, (D) from 5 to <75% by weight of freezing point-lowering alcohols selected from among alkanols, glycols, polyalkylene glycols and glycerol, (E) from 5 to 90% by weight of vegetable and/or fatty oils, (F) from 0 to 5% by weight of water and (G) from 0 to 5% by weight of conventional emulsifiers. The formulation is particularly suitable for protecting zinc or zinc-plated components or surfaces or cadmium or cadmium-plated metallic surfaces against corrosion caused by runway deicing compositions used at airports.
