Abstract
A free flowing powder of discrete particles of a polar group-containing modified propylene polymer (MPP) is disclosed. This MPP powder has an average particle size of less than about 5 microns and comprises about 25-45 wt. % of discrete particles of the MPP and about 55-75 wt. % of a liquid which is a solvent for a film forming resin material, all wt. percentages being based on the total weight of the powder. The preferred MPP is maleic anhydride polypropylene. The preferred film forming resin solvent is methyl ethyl ketone (MEK). The MPP powder is adapted to be suspended in a primer composition containing a film forming resin, preferably an epoxy resin.
