Patent number: 5922473Abstract: Opaquely pigmented or thick filmed powder coatings for heat sensitive substrates, such as wood, wood composites, for example, medium density fiber board, and plastics, that can be fully cured, especially near the substrate, through the incorporation of a dual cure system in the powder comprising a thermal initiator, such as a peroxide, along with a UV initiator. The UV initiator cures the surface, while the thermal initiator cures at the substrate. Surprisingly, virtually no pregelation occurs during the heated melt and flow out step prior to UV curing. Consequently, the hardened film finish formed on the surface exhibits exceptional smoothness which is comparable to that of traditional UV curable powders. The hardened film finish is also fully cured throughout and exhibits exceptional adhesion to the substrate which cannot be achieved with traditional UV curable powders that have been pigmented.Type: GrantFiled: December 26, 1996Date of Patent: July 13, 1999Assignee: Morton International, Inc.Inventors: Jeno Muthiah, Andrew T.

Patent number: 5536573Abstract: A thin-film heterostructure bilayer is formed on a substrate by a molecular self-assembly process based on the alternating deposition of a p-type doped electrically conductive polycationic polymer and a conjugated or nonconjugated polyanion or water soluble, non-ionic polymer has been developed. In this process, monolayers of electrically conductive polymers are spontaneously adsorbed onto a substrate from dilute solutions and subsequently built-up into multilayer thin films by alternating deposition with a soluble polyanion or water soluble, non-ionic polymer. In contrast to a deposition process involving the alternate self-assembly of polycations and polyanions, this process is driven by non-covalent bonded attractions (for example, ionic and hydrogen bonds) developed between a p-type doped conducting polymer and a polymer capable of forming strong secondary bonds. The net positive charge of the conducting polymer can be systematically adjusted by simply varying its doping level.Type: GrantFiled: July 6, 1994Date of Patent: July 16, 1996Assignee: Massachusetts Institute of TechnologyInventors: Michael F.
