TYPE :
Penetrating Lubricant Containing PTFE PROD.# 0174
BENEFITS : Zep 45 is an aerosol penetrating lubricant fortified with friction-reducing substances, and a fluorotelomer dispersion. Zep 45 penetrates rapidly to loosen parts that are frozen due to wear, corrosion, and heavy grease or grime build-up. Zep 45 provides excellent and long lasting lubrication to moving parts. Micron size particles work like thousands of tiny ball bearings to dramatically reduce friction and wear. Zep 45 deposits a protective film to retard corrosion, prolong the life of machinery, and reduce down-time. The solvent action of Zep 45 removes accumulations of grease and grime from surfaces to allow contact with the lubricating, protective film. The lubricating film remains effective over a wide temperature range (from minus 55 degrees Fahrenheit to 475 degrees Fahrenheit.). Zep 45 is excellent for use on industrial machines, business machines, motor shafts, guns, sports equipment, shop tools, saws and drills, electric motors, vending machines, locks, hinges, rollers bearings, conveyors, pulleys, nuts and bolts, all rusted and corroded parts. Use on any surface that slips, slides, rubs, rolls, moves, turns, twists, or pivots.
