  • Patent number: 6784222
    Abstract: An electroconductive coating composition which function as a sealer/primer includes (a) a radiation curable, polymerizable compound, (b) a photoinitiator and (c) a conductive pigment. The conductive pigment may be a mixture of pigment including a blend of conductive pigments as well as conductive pigment. Conductivity enhancers may, also, be added. The polymerizable compound is, preferably, a U curable acrylate functional compound which may be monofunctional or polyfunctional. The composition is particularly useful for sealing and priming SMC panels.
    Type: Grant

  • Patent number: 6231931
    Abstract: A method of coating a wooden substrate or surface comprising the steps of depositing a layer of ultraviolet light curable polymer in an uncured form to at least one surface of a wooden substrate; and curing said polymer with an amount of UV energy sufficient to polymerize said polymer. The method optionally comprising the further steps of: scuffing the surface of the cured polymer; depositing a second layer of ultraviolet light curable polymer in an uncured form to the scuffed surface; and curing the second layer of ultraviolet light curable polymer with an amount of UV energy sufficient to polymerize said second layer. The method also contemplates a further step comprising scuffing the surface of the cured polymer; and depositing a top coat thereon.
