  • Publication number: 20100032074
    Abstract: The present invention relates to dialdimines of the formula (I) and emulsions and uses thereof. In particular, they can be used for the preparation of pasty curing agent or accelerator components for polymers having isocyanate groups, which lead to very high early strength, which have good flow behaviour on pumping and which can be formulated without VOC solvents, in particular without N-alkylpyrrolidones. These components can be homogeneously or inhomogeneously mixed in an outstanding manner, in particular in a laminar manner, with components which contain polyurethane polymers having isocyanate groups, the two-component compositions thus obtained curing rapidly, having extremely high early strength and remaining without annoying weaknesses.

  • Patent number: 7655718
    Abstract: Zinc carbonates such as carbonic acid zinc salt, zinc carbonate hydroxide monohydrate, zinc bicarbonate, zinc tetraamine carbonate, zinc ammonium carbonate, carbamic acid zinc salt and zinc carbamate can initiate hardening of polyurethane coatings and decrease the coating tack-free time. The decreased tack-free times facilitate earlier application of additional polyurethane layers and earlier return of a coated article to service, and can provide improved floor finishes.

    Abstract: A novel method of preparing an aqueous dispersion of non-uniform polyurethane particles which comprises (a) preparing at least two isocyanate-terminated polyurethane prepolymers having different hydrophilicities; (b) preparing a uniform mixture of said prepolymers; and (c) dispersing the mixed prepolymers in an aqueous medium. The resulting dispersion of the prepolymers may optionally be chain extended. This method enables the preparation of core-shell particles as well as particles of other morphologies, including “raspberry”, interpenetrating network, “salt-and-pepper”, “ice-cream cone” and particles of gradient composition. Similarly, an aqueous dispersion of two different polyurethane polymers may be obtained by first preparing at least two different isocyanate-terminated polyurethane prepolymers, preparing a uniform mixture of such prepolymers and thereafter dispersing the mixture in an aqueous medium.

  • Patent number: 7576157
    Abstract: An aqueous dispersion of polyurethane composites is made by forming a dispersion of urethane prepolymer or polymer and ketone functional molecule by dispersing them in an aqueous media and adding a hydrazine functional molecule. When the ketone functional molecule is derived from levulinic acid and epoxidized vegetable oil, the resulting urethane dispersion has enhanced coalescence with less need for coalescing aids.

  • Publication number: 20090197006
    Abstract: This invention relates to a protected organotin-based catalyst system for polyurethane synthesis that is useful in coatings applications. The catalyst has low activity in the absence of oxygen. When a coating mixture comprising the catalyst is sprayed and/or applied to a substrate as a thin film in air, the catalyst is activated. For solvent-based refinish systems comprising hydroxyl and isocyanate species at high solids levels, the catalyst system therefore provides extended viscosity stability, i.e., pot life.
