Abstract

Percompound are coated with an epoxide resin, cross linked in situ by a hardener effective 100 degrees C, by spraying a resin and hardener soln. on to the per compound particles held in a fluidised bed by an ascending inert gas, or by distributing a soln. of the resin and hardener on a revolving bed of the cpds. Used esp. for coating Na percarbonate for using in washing powders.
