ABSTRACT:
A friction material in the form of a substantial percentage of cured or polymerized powdered nylon and/or teflon resin is mixed in a binder which is mainly fluid epoxy resin and an activator therefor, and applied to the threaded portion of a threaded member. The epoxy resin is reacted by the activator at room temperature or at least at a temperature well below the fusion point of the nylon or teflon particles to bond the powder particles together and to establish a bond to the thread surfaces to form a substantially uniform mixture of the powder particles and binder and to form a substantially solid, non-tacky, resilient friction element strongly bonded to the thread surfaces and frictionally interfering with the threads of a mating threaded member.
