Philip J. Zaluska has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Isocyanate blocked imidazoles and imidazolines for epoxy powder coating
    Patent number: 4335228
    Abstract: This invention relates to the use of an isocyanate blocked imidazole or imidazoline compound as a catalyst for effecting cure of powdered epoxy resins. The isocyanate blocked imidazole or imidazoline imparts an extended pot life to a curable epoxy powder coating composition while effecting cure at substantially lower temperatures than normally would be required and with faster cure times.
    Type: Grant
    Filed: February 27, 1978
    Date of Patent: June 15, 1982
    Assignee: Air Products and Chemicals, Inc.
    Inventors: Burton D. Beitchman, Philip J. Zaluska
  • Amine salts of tertiary amino acids
    Patent number: 4232152
    Abstract: Amine salts of tertiary amino acids have been found to be effective as catalysts for polyurethane synthesis and they have been found to exhibit delayed action, in many instances, in the polymerization of urethanes. Typically, the amine salts of tertiary amino acids are formed by initially reacting a primary or secondary amine with an aldehyde and disubstituted acid to form a Mannich adduct and then reacting the resulting Mannich acid adduct with an amine.

  • Catalyst for epoxy powder coatings
    Patent number: 4161575
    Abstract: This invention relates to a catalyst system comprising a triethylene diamine salt of thiocyanic acid for epoxy powder coatings, the epoxy compound having a lower softening point of not less than 40.degree. C. The catalysts for these coatings have latent activity in that they remain substantially inactive during mixing and extruding, but are highly effective at the cure temperatures.

  • Amine salts of amino acids as delayed action catalysts
    Patent number: 4115634
    Abstract: The amine salts of amino acid compositions have been found to be effective as a delayed action catalyst for organometallic catalyzed urethane synthesis. The acid which provides the basis for the salts is characterized generally by reacting an amine with an unsaturated acid, or with formaldehyde and hydrogen cyanide followed by hydrolysis of the resulting nitrile.

  • Tertiary amino acid and tertiary amino acid-nitrile delayed action catalyst compositions
    Patent number: 4086213
    Abstract: Tertiary amino acid and tertiary amino acid-nitrile compositions have been found to be effective as delayed action catalysts for polyurethane synthesis. They are particularly effective when used in combination with an organometallic such as an organo tin composition. These compositions generally comprise the reaction product of a primary or secondary amine, an aldehyde and disubstituted acid.
