  • Publication number: 20150051319
    Abstract: The present invention pertains to the use, in the manufacture of an aqueous formulation with a hydraulic binder base, of a combination of at least one comb-branched copolymer having a (meth)acrylic skeleton, onto which are grafted side-chains terminated by a hydrophilic group, and at least one ASE acrylic polymer. This results in improving the workability of said formulation, without causing a segregation phenomenon.

  • Patent number: 8921479
    Abstract: New associative thickening agents belonging to the category of HASEs (Hydrophobically modified Alkali-Soluble Emulsions). These products contain an original associative monomer with a base of alkylcyclohexanol akoxylates. Their thickening power is greater than the HASE associative thickening agents of the prior art containing grafted alkyl phenols. An efficient substitute product is therefore available, which is free of alkyls phenols, matching current market demand.

  • Patent number: 8895630
    Abstract: New associative thickeners of the HEUR type (Hydrophobically modified Ethylene oxide URethane) whose hydrophobic monomer is based on alkyl cyclohexylols. These are new polyurethanes that allow a broad thickening of a medium shear gradient aqueous formulation while limiting the increase in the low shear gradient viscosity. The invention also concerns the compositions containing them and their uses in different formulations such as aqueous paints.

  • Publication number: 20140296432
    Abstract: The present invention relates to new acrylic associative thickening agents which, when polymerized in the presence of particular polyglycerols, ultimately result in an increase of the open time of the paint or of the thick coating in which they are incorporated. By so doing, painters and applicators will have more time to work the paint layers gradually or to correct imperfections such as paint droplets, traces of brushes and filling-knives.

  • Patent number: 8841374
    Abstract: A method for manufacturing an aqueous suspension of calcium carbonate by grinding in an aqueous medium in the presence of an acrylic grinding aid agent and of an alkali carbonate salt. These salts enable the quantity of grinding aid agent used to be reduced, for an equivalent level of performance in terms of rheology and granulometry of the suspensions. The method includes a first step of manufacture of the alkali carbonate salt within the aqueous solution of acrylic polymer itself, through the addition of alkali hydroxide and bubbling of carbon dioxide.
