Controlled release coolant additive composition
A controlled-release coolant additive composition for use in engine coolant systems comprising a core containing at least one coolant additive component and a polymeric coating encapsulating said core. The controlled released coolant additive composition slowly releases the coolant additive components to an engine coolant system, thereby delivering an effective concentration level of coolant additive components over an extended period. The controlled-release coolant additive composition maintains a minimum concentration level of active coolant additive components in the coolant system.
