    摘要： A curable film-forming composition of 5 to 95 weight percent (based on the total resin solids weight in the composition) of a crosslinking agent; 5 to 95 weight percent of a polymer containing functional groups reactive with the crosslinking agent; and 0.01 to 15 weight percent of at least one additive selected from a reaction product of phosphorous acid and: at least one diepoxide; at least one diepoxide and at least one anhydride; at least one diepoxide and at least one anhydride, chain extended with at least one diol; at least one monoepoxide and at least one anhydride, chain extended with at least one diepoxide; and mixtures thereof. The additives in the composition prevent thermal oxidation, minimizing visual effects (i.e., yellowing). A multi-component composite coating includes a base coat and a top coat which may be derived from the above curable film-forming composition.

    摘要： A composition including a block copolymer that includes a first block of residues of a first low surface tension (meth)acrylate monomer, a second block containing residues of a second radically polymerizable ethylenically unsaturated monomer that is free of hydroxyl groups and amine groups, and, optionally, a third block containing residues of a third radically polymerizable ethylenically unsaturated monomer that is free of hydroxyl groups and amine groups. The block copolymer is prepared by controlled radical polymerization and has a polydispersity index of less than 2.5. The composition may further include a first reactant having functional groups and a second reactant having functional groups that are coreactive with the functional groups of the first reactant. The composition may be a thermosetting composition where the block copolymer is present as a flow control agent.

    摘要： Provided are block copolymers containing at least two blocks are provided and comprise: (a) a first block containing residues of at least one first ethylenically unsaturated radically polymerizable monomer that is free of hydroxy functionality, e.g., 2-ethylhexyl methacrylate, and, optionally, a minor amount of at least one hydroxy functional ethylenically unsaturated radically polymerizable monomer, e.g., hydroxypropyl methacrylate; and (b) a second block containing residues of at least one second ethylenically unsaturated radically polymerizable monomer that is free of hydroxy functionality, e.g., iso-butyl methacrylate, and, optionally, a minor amount of at least one hydroxy functional ethylenically unsaturated radically polymerizable monomer. The calculated Tg of the second monomer of the block copolymer is at least 20 DEG C greater than the calculated Tg of the first monomer. Also provided are thermosetting coating compositions that contain the block copolymers as flow additives.

    摘要： A catalytic tin carboxylate adduct, which is useful as a catalyst in epoxy-acid coating compositions, is the reaction product of (A) a mono-, di-, or poly-carboxylic acid functional compound and (B) an organotin compound containing one to three aryl groups and at least one halogen or hydroxyl group attached to the tin atom. There is also provided an epoxy-acid coating composition, which incorporates this catalytic tin carboxylate adduct. The epoxy-acid coating composition is advantageous as an automotive topcoat, particularly as a clear coat composition because it exhibits good appearance, durability, stability and generates no, or extremely low levels of benzene during the curing process.
