Abstract: A polymeric formulation comprising at least one first epoxy resin having a density between 100 and 10,000 Pa·s, a blocked isocyanate, a polymer comprising hydroxy functional groups, a thermoplastic resin and a cross-linking agent, the polymer comprising hydroxyl functional groups with a hydroxyl content in the range 0.65 to 0.95 meq/g, the isocyanate-equivalents-to-polymer-OH-equivalents rate being in the range 0.60 to 1.1. The first epoxy resin is substantially semisolid at room temperature, the formulation comprising at least one second epoxy resin substantially liquid at room temperature, the first and second epoxy resins being present in a weight ratio from 60:40 to 80:20. These formulations are advantageously used for manufacturing prepregs and articles of composite material according to a dry winding process. By virtue of improved stability, a higher glass transition temperature, and a rheological profile result which can be chemically tailored to the needs of the impregnation/dry winding process.

Abstract: Liquid thickener for aqueous systems containing, as viscosity suppressing agent, from 5 to 40% wt of ethoxylated mono- and/or di-glycerides of carboxylic acids having from 6 to 18 carbon atoms, from 15 to 40% wt of a polyurethane associative thickener, obtained from the reaction of at least one organic polyisocyanate, at least one water soluble polyether diol and at least one hydrophobic capping agent containing from 10 to 24 carbon atoms, from 20 to 80% wt of water, and which is devoid of organic solvents, volatile organic compounds and other viscosity suppressing agents.

Abstract: The present invention relates to stable aqueous dispersions of non-ionic blocked polyisocyanate obtained from the reaction of a polyisocyanate, a blocking agent and a non-ionic alkoxylated diol and to the process for their s preparation; the invention also relates to the use of these aqueous dispersions in textile printing pastes and in the oil and/or water-repellent finishing of textiles.
