Abstract
Abstract Band-ply lubricant concentrates are disclosed which are useful in the preparation of both solvent and water based formulations. Unexpected advantages of greater formulation latitude and product stability have been found. The concentrates consist of (A) an alkylene oxide polymer, (B) unique siloxane copolymer dispersing agents, (C) a polydimethylsiloxane fluid, and in some instances (D) mica or talc.
