An abrasive article comprising a nonwoven substrate material impregnated with a first and second formulation. The first and second formulations have broad spectrum antimicrobial effectiveness against one or more microbial organisms. The first and second formulations include the same or different polymer compositions, which include one or more antimicrobial agents and abrasive particles uniformly dispersed in the polymer compositions.

This invention relates to abrasive flap wheel that include hybrid fabrics. This invention also relates to methods of making and using said abrasive flap wheels. The claimed processes and systems related to the use and manufacturing of abrasive flaps are improved and cost effective.

Abrasive flap wheels including hybrid fabrics

An abrasive product includes a plurality of abrasive particles and a resin binder cured from a resin composition that includes an aqueous dispersion of melamine methylol having a melamine-to-formaldehyde molar equivalent ratio of between about 1:1 and about 1:3.2, wherein the aqueous dispersion has a pH in a range of between about 8 and about 10. The composition also includes a formaldehyde-based resins, such as a urea-formaldehyde resin or phenol-formaldehyde resin. The melamine methylol comprises between about 1 wt % and about 50 wt % of the combined weight of the formaldehyde-based resin and the melamine methylol.

Melamine methylol for abrasive products

A resorcinol-modified phenolic resin composition is formed by reacting a basic catalyst, formaldehyde, water and a benzene-ol to form an intermediate composition to which resorcinol is subsequently added to reduce the presence of free formaldehyde. Optionally, an alkanolamine can be combined and reacted with the resorcinol-modified phenolic resin composition to form a resorcinol-alkanolamine-modified phenolic resin composition. The resorcinol-modified phenolic resin and the resorcinol-alkanolamine-modified phenolic resin compositions can be employed to coat abrasive products having a relatively low free formaldehyde content.
