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.
Claims20
A substantially 100% solids sealant composition for application to
- a porous surface which comprises:
- an acrylate-methacrylate mixture, the acrylate-methacrylate mixture comprising at least an acrylate oligomer and at least a methacrylate oligomer, the acrylate oligomer having a lower molecular weight than the methacrylate oligomer;
- a functionalized resin having functionality of greater than 2 and a dynamic viscosity between 1,000 to 100,000 centipoise as measured by ASTM D2196;
- an unsaturated fatty acid triglyceride oil;
- and
- an organic photoinitiator;
- wherein the organic photoinitiator includes:
- a phosphine oxide and a phenyl ketone;
- a first propanone;
- and
- a mixture of a first benzophenone, a second benzophenone, and a second propanone.
A method comprising mixing:
- an acrylate-methacrylate mixture, the acrylate-methacrylate mixture comprising at least an acrylate oligomer and at least a methacrylate oligomer, the acrylate oligomer having a lower molecular weight than the methacrylate oligomer;
- a functionalized resin having functionality greater than 2 and a dynamic viscosity between 1,000 to 100,000 centipoise as measured by ASTM D2196;
- an unsaturated fatty acid triglyceride oil;
- and
- an organic photoinitiator;
- wherein the organic photoinitiator includes:
- a phosphine oxide and a phenyl ketone;
- a first propanone;
- and
- a mixture of a first benzophenone, a second benzophenone, and a second propanone.
