Abstract

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.

Abstract

An essentially 100% solids, single-component, UV curable, low-viscosity, penetrating sealant composition for wood substrates and other porous substrates is prepared from an acrylate-methacrylate mixture, a functionalized resin, an unsaturated fatty acid triglyceride oil, and a photoinitiator. The sealant composition may further contain a metal catalyst, an amine synergist, fillers, pigments, dyes, flow and leveling additives, air release chemicals, UV absorbers, hindered amine light stabilizers, fungicides, insect repellents, and/or mold inhibitors. The sealant composition exhibits fast cure times along with resistance to degradation.
