  • Publication number: 20180037756
    Abstract: A method of coating a carbon nanotube material with a solventless coating composition is described. The resulting coating has been shown to preserve the conductivity of the conductive layer and protect the conductive layer from the effects of subsequent coating compositions. Examples are shown in which the coating formulation comprises a polyol and an isocyanate. A layer material comprising a polyurethane coating on a carbon nanotube network layer is also described.

  • Patent number: 8722147
    Abstract: A corrosion resistant primer coating comprises one or more corrosion inhibiting additives; and one or more nonaqueous resins, and the method of making and using the primer coating. The corrosion inhibiting additive comprises metal ferrate(IV) compounds, metal ferrate(V) compounds, metal ferrate(VI) compounds, or a mixture thereof (collectively called the ferrate compound). The ferrate compound has a low solubility in water in the range of about 0.001 ppm to about 2000 ppm at a temperature in the range of about 0° C. to 71° C.

  • Patent number: 8686092
    Abstract: A series of resins were synthesized using a range of bio-based materials to control the molecular architecture, and therefore the properties, of the inventive resins. The utility of these resins was demonstrated in the formulation of powder coatings, such as ?-hydroxy amide crosslinked and hybrid types. Generally, the bio-based resins flowed out on heating faster than conventional petrochemically-based resins, allowing the use of lower temperatures in the curing oven than is typically possible and a more active catalyst system, especially in the carboxylic acid-epoxy crosslinked hybrid coating formulations.

  • Patent number: 6503999
    Abstract: An aqueous coating composition comprising an active hydrogen-containing polymer, an isocyanate, and beta-hydroxyalkylamide is disclosed. The polymer can be any number of polymers containing hydroxyl, amine and/or thiol groups, such as an acrylic polyol, a polyester polyol, and mixtures thereof. The hydroxylalkylamide has been shown to decrease the time in which the coating achieves hardness and, in the case of the polyester polyol system, increases the hardness that is achieved. The present compositions also provide resistance to chemical exposure. Methods for coating a substrate and the substrates coated thereby are also disclosed.
