Abstract
A water soluble cable lubricating composition and method involves a lubricant in liquid or gel form that possesses the ability to adhere to the surface to be lubricated. The composition includes an aqueous solution of from about 1 to 4% of a water soluble cellulose derivative, such as carboxymethyl cellulose, and from about 1/2 to 2% of polyacrylamide. The lubricant may also include a hygroscopic agent such as ethylene glycol to prevent the lubricant from drying out too rapidly in use.

A cable lubricant comprising from about 1 to about 4% by weight of a water soluble cellulose derivative, from about 1/2 to about 2% by weight of polyacrylamide and from about 75% to about 98.5% by weight water.
A cable lubricant comprising from about 1 to about 4% by weight carboxymethyl cellulose, from about 1/2 to about 2% by weight polyacrylamide, from about 5 to 15% by weight of a hygroscopic agent and about 75 to about 98.5% water.
A cable lubricating method for lubricating cable preparatory to pulling the cable through a housing, comprising:
- preparing an aqueous, colloidal composition of polyacrylamide, carboxymethyl cellulose, and a hygroscopic agent;
- applying the composition in a colloidal film to the surface of the cable.
