Abstract
An adhesive composition for use in flooring applications that includes a moisture curable polymer system; a calcium carbonate filler system having a first spheroidal particle of calcium carbonate having an equivalent spherical mean diameter of 70 nanometer (nm) to 15 micrometer (μm) and a second spheroidal particle of calcium carbonate having an equivalent spherical mean diameter of greater than 15 μm to 200 μm; a seed oil based fatty acid ester; and a silane based adhesion promoter. The adhesive composition provides low viscosity along with high shear resistance, which helps to retain the troweled ridges to enable maximum coverage.
