Starch graft poly(meth)acrylate blast media

摘要

The invention discloses a starch graft poly(meth)acrylate blast media which is effective in paint removal. The media is superior to a physical blend of the components (i.e., starch and acrylic polymers) and to either a starch polymer or an acrylic polymer used singly. The hardness of the media is between 65-90 Shore D.
