  • Patent number: 7166675
    Abstract: A thermosetting protective and/or decorative coating composition that includes a co-reactable solid, particulate mixture of a film-forming material that includes a copolymer containing functional groups and a crosslinking agent having at least two functional groups that are reactive with the functional groups in the copolymer. The film-forming material makes up from 20 to 95 wt. % and the crosslinking agent makes up from 5 to 80 wt. % of the composition. The composition is applied as a coating and cured, forming a bicontinuous morphology where the film-forming material and the crosslinking agent form separate phases resulting in a low gloss coating as indicated by a specular gloss measurement of not more than 10 gloss units measured at 60° with an appropriate instrument. A method of coating a substrate using the composition, substrates coated using the method, and a multi-component composite coating composition that includes the composition are disclosed.

  • Publication number: 20070009740
    Abstract: A coating composition is provided comprising (a) a polymer containing reactive functional groups; (b) a curing agent having reactive functional groups that are reactive with the functional groups in the polymer in (a); and (c) a polymeric material different from (a) and (b) having functional groups. The functional groups in components (a) and (b) are more reactive with each other than with the functional groups in component (c) such that upon curing, at least a portion of the functional groups on component (c) remain unreacted. A coating layer formed from the composition upon application to a substrate has surface regions and a bulk region, and the concentration of component (c) at one or more surface regions is greater than the concentration of component (c) in the bulk region of the coating layer. The composition can be used in multi-layer composites containing two or more coating layers.
