  • Methods for making elastomers, elastomer compositions and related elastomers
    Patent number: 10100223
    Abstract: Methods of producing an elastomer are disclosed that include (I) applying an actinic radiation curable composition preferably selected from a urethane (meth)acrylate, an allophanate urethane (meth)acrylate or a lactone-containing (meth)acrylate to a substrate at a thickness of at least 0.25 mm (10 mils); (II) exposing the composition ultraviolet radiation to produce a cured film; and (III) removing the film from the substrate. Related compositions are also disclosed.

  • Radiation curable compositions
    Patent number: 7268172
    Abstract: The present invention is directed to a composition curable by radiation having a wavelength of 300 nm or more, a method of producing a coated substrate using such composition and the coated product so-produced. More particularly, the composition of the present invention comprises A) from about 1 to about 99% by weight of an unsaturated polymer or oligomer, B) from about 1 to about 99% by weight of an unsaturated epoxy acrylate, C) one or more photoinitiators, and, optionally, D) one or more solvents.

  • UV curable coating composition
    Publication number: 20050154076
    Abstract: The present invention is directed to a non-aqueous composition curable by UV radiation broadly comprising a mixture of two UV curable urethane acrylates. The invention is also directed to a coating process using such composition. One of the urethane acrylates is the reaction product of an isocyanate and a specific OH functional lactone ester (meth)acrylate. The other urethane acrylate is the reaction product of an isocyanate and a specific hydroxy functional (meth)acrylate.

  • Acrylate-functional blocked polyisocyanate resin for UV/thermally curable coatings
    Publication number: 20050090620
    Abstract: Solvent-based, dual cure coatings incorporating thermally curable blocked polyisocyanates, which also contain unsaturated linkages, and a method for preparing these coatings. The unsaturated linkages, such as acrylate groups, can be crosslinked by free-radical mechanisms such as UV curing.

  • UV-curable waterborne polyurethane dispersions for soft touch coatings
    Publication number: 20050003102
    Abstract: The present invention is directed to a waterborne, UV-curable polyurethane emulsion and the use thereof in producing soft touch coatings. The emulsion is prepared by a) reacting specified hydroxy-functional components with di- and/or polyisocyanates, b) forming a dispersion of the resultant product with water and reacting the dispersion with amine functional materials.
