  • Patent number: 9969900
    Abstract: The present invention is directed to methods of improving burnish resistance of substrates comprising: (1) applying to at least a portion of the substrate a curable film-forming composition comprising: (a) a polymeric binder comprising at least one polymeric resin having reactive functional groups; (b) a curing agent containing functional groups that are reactive with the reactive functional groups of (a); and (c) silica particles that have been functionalized on their surfaces with an amino silane so as to impart the surfaces with primary amino functional groups; and (2) (a) heating the coated substrate to a temperature and for a time sufficient to cure the curable film-forming composition or (b) allowing a time sufficient to cure the curable film-forming composition under ambient conditions. The present invention is further directed to solventborne, curable film-forming compositions comprising the components (a) (b) and (c) above.

  • Patent number: 8791223
    Abstract: Methods of catalyzing chemical reactions are provided. A tri-substituted phosphine having at least one substituent that is an alkyl group is added as a catalyst to reaction mixtures. Reaction mixtures contain uretdiones, anhydrides, or isocyanate functional materials including isocyanurates, in various combinations with hydroxyl, thiol, and/or amine functional materials. Curable compositions comprising these catalysts and reaction mixtures are also provided.

  • Publication number: 20140072815
    Abstract: The present invention is directed to curable film-forming compositions comprising: (a) a polymeric binder comprising at least one polymeric resin having reactive functional groups; (b) a curing agent containing functional groups that are reactive with the reactive functional groups of (a); and (c) silica particles that have been functionalized on their surfaces with an amino silane so as to impart the surfaces with primary amino functional groups. After application to a substrate as a coating and after curing, the curable film-forming composition demonstrates an initial 85° gloss of less than 30 and an increase in 85° gloss of no more than 15 gloss units when subjected to various ABRASION TEST METHODS as defined herein.
