POWDER COATING OF THERMOSETTING ADHESIVES ONTO METAL SUBSTRATES TO ENABLE A FRICTION MATERIAL TO BE BONDED TO THE METAL SUBSTRATE

摘要

91099 The present invention relates to a method of manufacturing a composite friction element wherein a powdered solventless thermosetting adhesive is applied to a metal substrate and the product made therefrom. The metal substrate and thermosetting adhesive material are heated to allow the powdered solventless adhesive material to flow but not crosslink. A friction material is applied under heat and pressure to the adhesive material such that the adhesive material crosslinks and a composite friction element is formed.
