Abstract

Durability of elastomeric bellows-type suspension and drivetrain components, particularly constant velocity joint boots, is improved by coating the elastomeric boot with a thin, flexible, and lubricious coating formed by curing the admixture of epoxy resins, curing agents, an unsaturated polymerizable monomer, a free radical polymerization and/or grafting initiator, and a non-fugitive solid lubricant. The coating strongly adheres to the elastomer and greatly increases the longevity under severe operating conditions.
