Abstract:
A method for heat treatment of coatings for application to metal surfaces wherein a ceramic is positioned adjacent to the coating to be treated and the ceramic is exposed to a microwave beam having a predetermined frequency and power density which are sufficient to heat the ceramic to a desired temperature whereby the coating is adhered to an applied metal surface without temperature degradation of the metal.
Abstract:
A thermally curable coating is spin applied to the surface of a lens through a process that comprises the following steps: preparing a thermally curable coating composition, spin applying the coating onto one surface of a lens, and curing the coating. The process combines the best features both of the spin application technique and a thermally cured coating to obtain high productivity with high yield in the application process yet provide superior coating properties without requiring stripping or other pretreatment steps, which have negative attributes. The process can also incorporate the use of either a thermoset or a thermoplastic primer to enhance the coating adhesion.

Abstract:
A process for coating a substrate is provided which includes the following steps: (a) applying a waterborne base coat composition to a surface of the substrate; (b) applying infrared radiation at a power density of 1.5-30.0 kW/m2 and a first air stream simultaneously to the base coat composition such that a pre-dried base coat is formed upon the surface of the substrate; and (c) applying a second air stream in the absence of infrared radiation to the base coat composition such that a dried base coat is formed upon the surface of the substrate. Various embodiments of the invention are disclosed including continuous, batch, and semi-batch processes, which may include additional process steps, such as subsequent application of a topcoat. The process may be used to coat a variety of metal and polymeric substrates, for example, those associated with the body of a motor vehicle.

Abstract:
A closed space is formed in a reduced pressure drying station, and the closed space is brought to a vacuum state. In this state, an EB unit irradiates a wafer mounted on a hot plate with an electron beam to foam an insulating film material. Subsequently, the hot plate is raised to a predetermined temperature, and drying processing is performed under a reduced pressure. As described above, since the foaming processing is performed in the reduced pressure drying station, bubbles remain in the insulating film, so that the existence of the bubbles can decrease the relative dielectric constant.

A method of fabricating a decorative wood article includes the steps of applying a decorative overlay onto at least one surface of a wood article, applying a radiation curable powder coating onto the outer surface of the overlay, heating the applied radiation curable powder coating at a temperature sufficient to melt and flow the powder coating, and exposing the applied powder coating to radiation energy to cure the powder coating and form a film on the outer surface of the decorative overlay.
Abstract:
A composite article having large scale predictable dimensional stability comprises a metal foil backing having adhered thereto a layer of cured polymer having an exposed surface bearing a three-dimensional microstructure of precisely shaped and located functional discontinuities. The article is made by depositing a layer of a radiation curable composition onto a metal foil backing, contacting a master with a pattern capable of imparting a three-dimensional microstructure of precisely shaped and located functional discontinuities into the layer of radiation curable composition, while the layer of radiation curable composition is in contact with the master, exposing the curable composition to radiation to cure the composition, and separating the cured polymer layer on the metal foil backing from the surface of the master. Either the metal foil backing or the master may be radiation transmissive.

A process for the production of a multi-layer coating, wherein a primer layer which is electrically conductive in the at least partially cured state is applied by electrodeposition from an electrodeposition coating agent (I) to an electrically conductive three-dimensional object, at least partially cured exclusively by the action of near infra-red radiation substantially only on the surfaces of the object exposed to the radiation, and an additional coating layer is applied by electrodeposition from an electrodeposition coating agent (II) which is different from electrodeposition coating agent (I), and then this additional coating layer as well as completely uncured or incompletely cured area parts of the primer layer produced from electrodeposition coating agent (I) are cured.
