Abstract

The invention relates to use of a water dispersible isophthalic acid polymer as a dust free coating on particulates. The particles provide a timed release of the contents of the particle which allows for reduced amounts of active agents on the coatings and less interference between active agents in the coating or environment and the particulates.
