COATED ABRASIVE ARTICLE AND METHOD OF MAKING SAME

A coated abrasive article comprises a backing, a first binder (i.e., a make coat) on the backing, and a plurality of abrasive particles in the first binder. The first binder precursor is an energy-curable melt-processable resin containing an epoxy resin, a polyester component, a polyfunctional acryl...

Abstract A coated abrasive article comprises a backing, a first binder (i.e., a make coat) on the backing, and a plurality of abrasive particles in the first binder. The first binder precursor is an energy-curable melt-processable resin containing an epoxy resin, a polyester component, a polyfunctional acrylate component, and a curing agent for cross-linking the epoxy resin that is cured to provide a cross-linked make coating. The invention also relates to a method of producing such coated abrasive articles and a surface-treated porous cloth material. Article abrasif appliqué composé d'un support, d'un premier liant (par exemple, une couche de fabrication) sur le support, le premier liant contenant une pluralité de particules abrasives. Le précurseur du premier liant est une résine durcissable par application d'énergie, pour traitement par fusion, composée d'une résine époxy, d'un composant polyester, d'un acrylate polyfonctionnel et d'un agent de durcissement pour réticuler la résine époxy traitée de manière à former une couche de fabrication réticulée. L'invention porte également sur un procédé pour produire de tels articles abrasifs appliqués ainsi qu'un matériau textile poreux avec traitements de surface.
