Abstract
A wall compound for use in all applications and particularly well-suited for joining adjacent wallboards. The compound includes a latex resin, a thickener, fibers, and a filler material. In some embodiments, the repair compound is configured to exhibit at least one of yield stress and pseudoplastic-type behavior. In some embodiments, the compound includes hydrophobic and hydrophilic fibers of different morphologies. In some embodiments, the wall compound includes one or more associative thickeners.
Claims18
A wall compound comprising:
- a latex resin or resin binder present in an amount of about 50% by weight or less, based on the total weight of the compound;
- a thickener package including a hydrophilic alkali swellable emulsion, wherein the thickener package is present in amount of 1% by weight or less, based on the total weight of the compound;
- hydrophobic dry fibrillated fibers and hydrophilic fibers;
- and
- a filler material consisting of substantially spherical synthetic inorganic filler, wherein the wall compound exhibits yield stress behavior, having a yield stress value of at least 200 and no greater than 1000 Pa, and wherein the compound exhibits a Viscosity at 1500 Pa of stress of no greater than 10 Pa·s, each as measured according to the description.
