    • In broadest terms, a wood filler composition of the present invention comprises: from about 11.50 to about 17.50 weight percent water; from about 14.40 to about 21.60 weight percent ceramic microspheres; from about 2.48 to about 3.72 weight percent wood flour; from about 0.32 to about 0.48 weight percent thickener; from about 0.80 to about 1.20 weight percent glass bubbles; from about 12.24 to about 18.36 weight percent acrylic latex emulsion; and from about 36.06 to about 54.10 weight percent calcium carbonate. The composition preferably has a pH in the range of from about 8.4 to about 8.8. Further the composition preferably has a viscosity of 200,000 to 300,000 cps as measured on a BROOKFIELD RV viscometer (helipath on) with a T/E spindle at 20 rpm and 25 DEG C.
    • 广义而言,本发明的木材填料组合物包含:约11.50至约17.50重量%的水; 约14.40至约21.60重量%的陶瓷微球; 约2.48至约3.72重量百分比的木粉; 约0.32至约0.48重量%的增稠剂; 约0.80至约1.20重量%的玻璃泡; 约12.24至约18.36重量%的丙烯酸胶乳乳液; 和约36.06至约54.10重量%的碳酸钙。 该组合物优选具有约8.4至约8.8的pH。 此外,该组合物优选具有200,000至300,000cps的粘度,如BROOKFIELD RV粘度计(helipath on)上用T / E心轴在20rpm和25℃下测量的那样
