  • Patent number: 8389608
    Abstract: Aminoplast-polythiol compositions resulting from the contact product, or cured reaction product, of an aminoplast resin composition and a polythiol composition are disclosed. Typically, the polythiol composition contains thiol ester molecules having an average of two or more thiol groups per molecule. Methods for preparing the aminoplast-polythiol compositions, methods for using the aminoplast-polythiol compositions to produce coatings and to coat substrates, and coatings and other articles produced using these aminoplast-polythiol compositions also are described.
    Type: Grant

  • Patent number: 8003748
    Abstract: Polythiourethane polymer compositions, methods of making the polythiourethane polymer compositions, and methods of using the polythiourethane polymer compositions are provided. The polythiourethane can be produced by contacting a thiol ester composition and an isocyanate to produce a mixture and then heating the mixture to produce the polythiourethane polymer. In some embodiments, the thiol ester compositions include thiol esters, hydroxy thiol esters, and cross-linked thiol esters.

  • Patent number: 7781484
    Abstract: Thiol ester compositions, methods of making the thiol ester compositions, and methods of using the thiol ester compositions are provided. In some embodiments, the thiol ester compositions include thiol esters, hydroxy thiol esters and cross-linked thiol esters. The thiol ester composition can be used to produce cross-linked thiol esters, sulfonic acid-containing esters, sulfonate containing esters and thioacrylate containing esters. The thiol ester compositions can be used to produce polythiourethanes. The polythiourethanes can be used in fertilizers and fertilizer coatings.

  • Patent number: 7585932
    Abstract: Poly(?-thioether ester) compositions, methods of making the poly(?-thioether ester) compositions, and methods of using the poly(?-thioether ester) compositions are provided. The poly(?-thioether ester) can be produced by contacting a thiol ester composition and an ?,?-unsaturated ester to produce a mixture and then heating the mixture to produce the poly(?-thioether ester). In some embodiments, the thiol ester compositions include thiol esters, hydroxy thiol esters, and cross-linked thiol esters.

  • Publication number: 20090124762
    Abstract: The present techniques relate to thiourethane compositions formed by reacting a reactive composition containing active molecules having an average of at least one thiol group per active molecule and an average of at least one hydroxyl group per active molecule with a monomer composition containing monomer molecules having an average of at least two isocyanate groups per monomer molecule. The reactions are performed in the presence of an amine catalyst, which may preferentially react thiol groups over hydroxyl groups, thus forming a thiourethane composition having, on average, more hydroxyl groups than thiol groups and more thiourethane groups than urethane groups, on a normalized basis.

  • Publication number: 20090124784
    Abstract: The present techniques relate to formulations that include a first part containing active molecules that have an average of at least one thiol group per active molecule and an average of at least one hydroxyl group per active molecule, and a second part containing monomer molecules that have an average of at least two isocyanate groups per monomer molecule. The composition may be mixed with a catalyst composition that contains at least one amine catalyst and at least one metal catalyst. This mixed catalyst composition will substantially cure a mixture of the first part and the second part within less than about 48 hours at ambient temperature.

  • Publication number: 20080214774
    Abstract: Thiourethane prepolymer compositions, thiourethane polymer compositions, methods of making the compositions, and methods of using the thiourethane polymer compositions are provided. The thiourethane polymer composition can be produced by contacting a thiol ester composition and an isocyanate composition to produce a prepolymer composition and then curing the prepolymer composition to produce the thiourethane polymer composition. The prepolymer composition can also include a property modifying agent. In some embodiments, the thiol ester compositions include thiol esters, hydroxy thiol esters, and cross-linked thiol esters.
