摘要：
A controlled release additive composition for use in aqueous coolant systems is disclosed and comprises a core containing at least one additive component and a polymeric coating including one or more defined polymers substantially surrounding the core. The controlled released additive composition slowly releases the additive component into the aqueous coolant of an open, circulating cooling water system, thereby delivering an effective concentration level of the additive component over an extended period.
