An active energy radiation unit includes a light source which radiates ultraviolet rays onto a target object, and a main gas supply mechanism which is disposed to be adjacent to the light source and ejects an inert gas. The main gas supply mechanism includes a receiving part which receives the inert gas, and a main ejection port which is provided at a position between the receiving part and the light source and closer to the target object than the receiving part. A flow path area from the receiving part to the main ejection port is constant.

A curing apparatus (400) includes a housing (402) having a sidewall (404) with an inlet (408) spaced apart from an outlet (410) along an axis, the housing defining an interior chamber (406). At least one opening (419) extends through the sidewall of the housing, for example from the inlet to the outlet. At least one ultraviolet radiation source (426) is operative for transmitting ultraviolet radiation into the interior chamber. At least one nozzle (436) is in flow communication with the interior chamber. The at least one opening is an open slot configured to receive a portion of an article carrier moving along a guideway outside of the housing such that an article supported by the article carrier moves through the interior chamber from the inlet to the outlet on the portion of the article carrier extending through the slot.

The present invention provides an active energy ray-curable coating composition including a poly[(meth)acryloyloxyalkyl] isocyanurate (A); a polyfunctional (meth)acrylate (B) having 4 or more (meth)acrylate groups; an acrylic resin (C); and at least one pigment (D) selected from the group consisting of a coloring pigment and a glitter pigment, wherein the acrylic resin (C) has a weight-average molecular weight in the range of 5,000 to 30,000 and a solubility parameter in the range of 9.0 to 11.5.

A method for creating a coating onto an inner diameter of conduit, whereby an injection nozzle is moved in a forward direction until its tip is aligned with the end of the conduit. Slurry is pumped from a reservoir into the injection nozzle and then is discharged through the tip of the injection nozzle. The slurry flows, distributes and spreads onto the surface of the conduit. The conduit is rotated and the nozzle is retracted as slurry continues to discharge from the nozzle to coat the remainder of the conduit.
