Abstract: Radiation curable, sprayable compositions are disclosed that include (a) an acrylated epoxy, and (b) at least one multi-functional acrylate monomer. The radiation curable, sprayable compositions of the invention include a material containing an amino group. Also disclosed are multi-layer composite coatings wherein at least one layer is deposited from such compositions.

Abstract: An apparatus is provided for curing a curable coating on a three-dimensional object having at least a top surface and a side surface, with the object being advanced along a generally horizontal path. The apparatus includes an elongated light source of radiating curing energy for curing the coating on the surfaces of the object. An open-sided, elongated concave reflector is positioned behind the elongated light source to provide a focus for the radiated curing energy onto the object. The reflector has a generally elliptical cross-section for radiating the curing energy along an energy concentration line generally coincident with the object. The elongated light source is generally at the source focal point of the elongated reflector. The reflector is angled such that a line that runs between the source focal point of the reflector and the energy concentration line extends on the order of 55°-77° from vertical.

Abstract: A process for providing a uniform coating of one hundred percent solids material on a substrate and a substrate having a uniform coating of one hundred percent solids material. Process parameters are controlled to provide for a sprayable, curable coating of one hundred percent solids material that can be used to coat three dimensional surfaces and provide a uniform thin film layer across all areas of the three dimensional surface.
