Abstract
An abrasive article which is made from a liquid resin composition containing no formaldehyde, which replaces the resol or urea-formaldehyde resin used as an adhesive in coated abrasives and the resol used as an impregnation resin in bonded abrasives. The liquid resin composition comprises a product that results from the oxidative cleavage of an unsaturated plant or animal oil, chosen from aldehydes, peroxides and mixtures of these compounds. The liquid resin composition can be used for the manufacture of coated and bonded abrasive articles.
