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.
