Abstract
A controlled-release additive composition for use in aqueous systems. The composition comprises a core containing at least one additive component and a polymeric coating encapsulating said core. The controlled released cooling additive composition slowly releases the additive components to aqueous system, thereby delivering an effective concentration level of additive components over an extended period.
