Description

ABSTRACT:
A coated abrasive article comprising a backing bearing on one major surface thereof a layer of abrasive grains overcoated with a loading resistant coating and on the other major surface thereof a layer of pressure-sensitive adhesive. The loading resistant coating comprises a lithium salt of a fatty acid. It may also contain additives selected from the group consisting of surfactants, wetting agents, binders, anti-foaming agents, fillers, plasticizers, and mixtures thereof. The use of a lithium salt of a fatty acid significantly reduces the amount of transfer between the loading resistant coating of a first coated abrasive article and the pressure-sensitive adhesive layer of a second coated abrasive article disposed within a package.
