  • Etherified carbamate crosslinking agents and their use in curable compositions particularly film-forming compositions
    Patent number: 6962958
    Abstract: A reaction product is useful as a crosslinking agent for polymers having functional groups reactive with the reaction product such as hydroxyl, carboxylic acid, amide, thiol, urea, carbamate and/or thiocarbamate groups, wherein the polymer includes an acrylic, polyester, polyether and/or polyurethane. The reaction product is derived from a) a polyisocyanate or polyisocyanurate, b) a hydroxyalkyl carbamate, c) an aldehyde and d) at least one monohydric alcohol.

  • Etherified carbamate crosslinking agents and their use in curable compositions, particularly film-forming compositions
    Patent number: 6716953
    Abstract: The present invention provides a reaction product of reactants comprising: a) a polyisocyanate; b) a hydroxyalkyl carbamate; c) an aldehyde; and d) at least one monohydric alcohol. Additionally provided is a composition of matter comprising the structure: where Q is a multi-valent organic moiety containing urethane linkages; X is H, —CH2OH, or —CH2OR′; R′ is an alkyl or aryl group having from 1 to 12 carbon atoms; and y is at least 2. The reaction product described above may have the structure (i). The reaction product and composition of matter are suitable for use as crosslinking agents in a variety of curable compositions further comprising at least one polymer having functional groups that are reactive with the crosslinking agent. Such curable compositions may be used as film-forming compositions.
