  • Patent number: 9309152
    Abstract: A process for the production of a solid dispersant for a hydraulically binding composition includes the steps of: providing at least one first polymer, which is a comb polymer having a polymer backbone comprising carboxyl groups; providing at least one second polymer, which is a condensate of, at least, an aromatic compound and formaldehyde; or a lignosulfonate; preparing an aqueous solution comprising the first and the second polymer; and spray-drying the aqueous solution to obtain the solid dispersant.

  • Publication number: 20160040050
    Abstract: A polyurethane-based composition is disclosed which includes a polyurethane prepolymer, a solvent, a plasticizer and a curing agent, wherein the curing agent contains a mononuclear aromatic polyamine, and is present in an amount such that the molar ratio of all amine functions in the polyamine to all isocyanate functions in the composition is at least 0.7 to 1. Such polyurethane-based compositions have proven effective for example as adhesives and fillers in the repair of elastic substrates since they can be processed quickly and readily even at low temperatures. Methods are also disclosed for bonding or repairing elastic substrates that include corresponding polyurethane-based compositions, and to use of the composition for bonding and repairing elastic substrates.
