Various embodiments disclosed relate to pore inducers and porous abrasive forms made using the same. In various embodiments, the present invention provides a method of forming a porous abrasive form including heating an abrasive composition including pore inducers to form the porous abrasive form. During the heating the pore inducers in the porous abrasive form reduce in volume to form induced pores in the porous abrasive form.

Pore inducer and porous abrasive form made using the same

A repair compound for use in all applications and particularly well-suited for large hole repair. The repair compound includes a latex resin, a thickener, fibers, and a filler material. In some embodiments, the repair compound is configured to exhibit pseudoplastic-type behavior. In some embodiments, the repair compound has a density of not greater than 4.0 lbs/gal. In some embodiments, the repair compound includes hydrophobic and hydrophilic fibers of different morphologies. In some embodiments, the repair compound includes HASE-type thickeners. In some embodiments, the repair compound includes a bimodal distribution of hollow glass microspheres from two different strength/size curves.

Repair compound and methods of use

Herein are disclosed wall repair compounds comprising at least one or more polymeric binder latex emulsions, one or more inorganic fillers, and comprising an amount of organic polymeric thickener that is less than about 0.1 percent by weight based on the total weight of the wall repair compound. In certain embodiments, the wall repair compound comprises an inorganic filler system selected such that such that synthetic inorganic fillers comprise essentially 100 percent of the inorganic filler used. In certain embodiments, the wall repair compound comprises one or more glycol ether smoothing agents.

Lightweight wall repair compounds

Dye compositions comprising rhodizonate dye particles encapsulated within a shearable hydrophobic organic encapsulant composition.

Dye compositions

A self-priming spackling compound includes between about 35% by weight and about 65% by weight acrylic latex resin, between about 20% by weight and about 50% by weight filler material, and between about 1% by weight and about 20% by weight water. In certain aspects, the latex resin may have an average latex particle size of less than about 0.18 microns, a minimum film formation temperature of less than about 15 degrees Celsius, and/or a glass transition temperature (Tg) of less than about 25 degrees Celsius. To further enhance the self-priming performance of the spackling compound, the formulation may further comprise a colorant such as titanium dioxide.
