Method to make a photoconductor drum having an overcoat using a dual curing process
A method of preparing an organic photoconductor drum having a protective overcoat on its outermost surface is provided. In an example embodiment, a photoconductor drum having an electrically conductive substrate, a charge generation layer, a charge transport layer and an outermost protective overcoat layer is provided. The photoconductor drum is cured using a two-step process. The first curing step applies either ionizing irradiation, such as with an electron beam or by gamma rays or applies non-ionizing irradiation such as ultraviolet light to the photoconductor drum. A mask is sized and placed over the print area of the initially cured photoconductor drum, thereby exposing the outermost edges of the photoconductor drum. The outer edges of the masked photoconductor drum is then exposed to a second curing step using ultraviolet light irradiation.

A laminate having excellent abrasion resistance to physical stimuli such as dust. The laminate comprises a base layer, a hard coat layer and a top coat layer comprising flaky metal oxide fine particles all of which are formed in this order. The flaky metal oxide fine particles are hardened by at least one method selected from the group consisting of ionizing material exposure, ionizing radiation exposure, infrared exposure, microwave exposure and high-temperature vapor exposure.
Method for additively manufacturing composite parts
A method of additively manufacturing a composite part comprises depositing a segment of a continuous flexible line along a print path. The continuous flexible line comprises a non-resin component and further comprises a photopolymer-resin component that is uncured. The method further comprises delivering a predetermined or actively determined amount of curing energy at least to a portion of the segment of the continuous flexible line at a controlled rate while advancing the continuous flexible line toward the print path and after the segment of the continuous flexible line is deposited along the print path to at least partially cure at least the portion of the segment of the continuous flexible line.

Electron beam irradiation process and polymerizable stain applied to wood planking
A process utilizes electron beam generated ionizing radiation or low energy electron irradiation to effect cure of polymerizable stain compositions applied to wood planking. The electron beam ionization process generates sufficient energy to break bonds and generate new cross-links within the polymeric stain composition thus bonding the stain strongly within the pores and surface of the wood planks further creating a durable treatment. The electron beam ionization process simplifies the curing process by eliminating or reducing the need for expensive photoinitiators. Pre-stained wood planking is suitable for exterior decking materials and building panels requiring a combination of color affected and durable finishes, thereby eliminating the need for field installation of pretreatments, stains, coatings and the like. These electron beam cured wood planks take on an assortment of appearances including clear, natural, translucent, and solid hues.
