Phospholipid dedusting agents for joint compounds
A drying-type joint compound, a setting-type joint compound, and/or a ready-mixed, setting-type joint compound can include a phospholipid dedusting agent. For example, a drying-type joint compound can include: (a) a primary filler at 50 weight percent (wt%) to 98 wt% on a dry basis, wherein the primary filler includes one of calcium carbonate, calcium sulfate dihydrate, and talc, and a mixture thereof; (b) a secondary filler at up to 25 wt% on a dry basis; (c) a binder at 1 wt% to 15 wt% on a dry basis; (d) a polymer thickener at 0.05 wt% to 3 wt% on a dry basis; (e) a phospholipid dedusting agent at 0.01 wt% to 3 wt% on a dry basis; (f) an additive up to 10 wt% o on a dry basis; and (g) water at a weight ratio of water to dry components of 1:6 to 2:1.
