LOCTITE® SF 7840™ (also known as LOCTITE Natural Blue) is a concentrated, water soluble, biodegradable cleaner and degreaser containing no harmful solvents. It is a blue liquid consisting of water, special solvents, surfactants and conditioners; it is non-flammable and non-caustic. It is used on engines, castings, valves, bearings, tanks and machinery as well as concrete floors and vehicles. It removes grease, lubricants, cutting oils, fuel oil, tar, de-icing salts, light carbon, wax and soot.
Typical Properties
- Blue liquid; specific gravity (25 °C) 1.02
Dilution (product:water)
- Heavy duty cleaning and degreasing (dip tanks, parts washers) 1:1–1:4
- Medium duty cleaning (concrete floors, pressure washing and steam cleaning equipment) 1:16–1:32
- Light duty cleaning (work areas, windows, walls) 1:64–1:128
Use and Storage
- Dilute with hot or cold water; soak or spray the parts, then wipe with a cloth or rinse; for best results use hot water, agitation or scrubbing and extended contact time
- At concentrations stronger than 1:20 it may damage painted surfaces; cleaner residues may inhibit the cure of anaerobic products
- Store unopened in a dry place at 8–21 °C
