  • Patent number: 7333876
    Abstract: The present invention comprises systems and methods for providing electronic quality control in a process for applying a polyurethane to a substrate. One aspect of the present invention includes a computer-implemented method for providing electronic quality control during manufacturing of a polyurethane coated article. The method can include providing a user interface for a user to input at least one operating characteristic associated with a process for manufacturing a polyurethane coated article. Furthermore, the method can include receiving a selection of at least one operating characteristic from the user, and receiving at least one condition associated with the operating characteristic. Moreover, the method can include monitoring a process for manufacturing a polyurethane coated article, wherein a change to the operating characteristic can be detected. The method can also include generating a notification if the at least one condition is detected.

  • Patent number: 6521298
    Abstract: The process for applying a polyurethane derived from VOC-free reactants wherein the reactants are polyol resin and isocyanate. The reactants are separately heated, proportioned and pressurized then the proportioned heated reactants are mixed together. The proportionate volume ratio of polyol resin reactant to isocyanate reactant is 1:1.05 to about 1:4. Combining the reactants initializes the formation of the polyurethane with a stoichiometric excess of the isocyanate reactant. The polyurethane reactants are sprayed onto a heated rotating substrate in an amount sufficient to create a polyurethane elastomer reinforcement layer after curing. The polyurethane reactants are polymerize or gel into an elastomer in the time range of 15 to about 120 seconds.
