Patent ID: 8459621

Claim:
A multi piece vehicle suspension component, the suspension component comprising: a first rigid component; a second resilient component, the second resilient component being formed of a microcellular urethane, the microcellular urethane having NCO groups, the first rigid component having complementary structure with respect to the second resilient component, the first rigid component connected to and overlaying a portion of the second resilient component; and a layer of bonding agent disposed on the first rigid component to prevent corrosion of the first rigid component, the bonding agent being an urethane electrocoating, the second resilient component molded on the bonding agent of the first rigid component, the NCO groups in the microcellular urethane having an affinity for the active molecules in the bonding agent and cross-linking to form a durable bonded layer thereby improving bonding between the first rigid component and the second resilient component and further improving cyclic fatigue of the multi piece vehicle suspension component.
