  • Photoactivatable water borne coating composition
    Patent number: 6987135
    Abstract: Photoactivatable water born coating composition comprising a) a (meth)acryloyl-functional polyurethane dispersion, with the (meth)acryloyl-functional polyurethane comprising 5 to 18 wt. % of alkylene oxide groups while the (meth)acryloyl functionality is in the range of 2 to 40, and b) a UV-initiator. Preferably, the (meth)acryloyl-functional polyurethane comprises 8 to 18 wt. % of alkylene oxide groups. More preferably, the coating composition comprises a reactive diluent.

  • Coating composition comprising a bicyclo-orthoester-functional compound, an isocyanate-functional compound, and a thiol-functional compound
    Patent number: 6548617
    Abstract: The invention pertains to a coating composition comprising a) a first compound comprising at least one bicyclo-orthoester group, b) a second compound comprising at least two isocyanate groups, and c) a third compound comprising at least one thiol group. The invention also relates to a process for curing the present coating composition. More particularly, the latent hydroxyl groups of the bicyclo-orthoester groups have to be deblocked and reacted with the isocyanate-groups of the second compound if the present coating composition is to be cured.

  • Coating composition comprising a reactive diluent
    Publication number: 20020122947
    Abstract: Coating composition comprising one or more compounds having functional groups which are reactive to olefinically unsaturated bonds, and a citraconimide functional compound, e.g., benzyl citraconimide, octyl citraconimide, or methoxy propyl citraconimide and/or an itaconimide functional compound as a reactive diluent. The reactive diluents are particularly suitable for use in oxidatively drying coating compositions, such as alkyd based coatings, or coating compositions which are curable by radical copolymerization.
