  • Patent number: 8296974
    Abstract: The present invention is a transparent thermoplastic polyurethane (TPU) comprising structural units of: a.) a diisocyanate; b.1) a polyester diol and b.2) a specific polyether diol and c.) a chain extender. The TPU has good combinations of light transmission and clarity, tensile strength, low temperature flexibility, and high moisture vapor transition rates compared to other commercial or known TPUs. A preferred example composition is a TPU that is based on MDI as the diisocyanate monomer, polycaprolactone as a polyester diol, an EO capped EO/PO polyether diol containing less than 20% EO, and butanediol as chain extender. These composition have good combinations of clarity, tensile strength, hydrolytic stability and processability compared to TPUs prepared using either polyester or polyether diols alone or the combination with a higher EO polyether diol.

  • Publication number: 20040259990
    Abstract: The present invention relates to a curable paint formulation and a curing paint formulation prepared therefrom. The curable formulation comprises a curable acrylic-based paint and a trialkylborane-organonitrogen complex. Curing of this formulation can be initiated by contact with a borane-displacing initiator. The curing paint formulation, when applied to a low surface energy substrate such as isotactic polypropylene, is capable of forming an adherent cured coating with little or no cross-hatch failure. Moreover, the application of the curing paint formulation onto the substrate can be carried out at room temperature and without the aid of substrate surface pretreatment or a tie layer.
