    Abstract: An abrasive product includes a plurality of abrasive particles and a resin cured with a polythiol group. A method of preparing the abrasive product includes contacting the plurality of abrasive particles with a curable composition that includes a resin and a polythiol group, and curing the curable composition to produce the abrasive product. A method of abrading a work surface includes applying an abrasive product to a work surface in an abrading motion to remove a portion of the work surface. A curable composition includes a formaldehyde resin and a polythiol group. A formaldehyde resin is crosslinked by a polythiol group. A method of crosslinking the formaldehyde resin includes reacting the polythiol group with the formaldehyde resin.

    Abstract: A one-step, in-situ, process for producing a high solids content emulsion or dispersion of partially or totally crosslinked urea formaldehyde (UF), melamine formaldehyde (MF), or melamine urea formaldehyde (MUF) resin droplets or particles, by forming a reaction mixture of (i) aqueous formaldehyde (formalin), (ii) at least one water-soluble protective colloid, (iii) water and (iv) optionally a surfactant, and mixing the reaction mixture in a reaction vessel; optionally adjusting the initial pH of the reaction mixture according to a desired value as needed; adding (i) urea or substituted urea, (ii) melamine or substituted melamine, or (iii) a mixture thereof, to the reaction mixture; and heating the reaction mixture to a temperature at which condensation takes place between the (i) urea or substituted urea, (ii) the melamine or substituted melamine, or (iii) the mixture thereof, and the formaldehyde to form a urea formaldehyde, melamine formaldehyde or melamine urea formaldehyde resin, and holding the reaction mixture at that temperature or a higher temperature, under mixing, for a period of time sufficient to achieve a desired degree of crosslinking in said urea formaldehyde, melamine formaldehyde or melamine urea formaldehyde resin; and cooling the reaction mixture. The droplet or particle size of the resulting resin dispersion can be controlled and adjusted by way of the present technique to the application requirements.
