LOCTITE 2400 is designed to secure at medium strength and seal threaded fasteners that are normally disassembled with standard hand tools. The product cures when sealed from air in closely fitting metal surfaces and prevents loosening and leakage from shock and vibration. LOCTITE® 2400™ is particularly suitable for less active substrates including stainless steel and coated surfaces such as Zinc-Flake coatings or electrolytic zinc plated surfaces. This locking compound tolerates light contamination from industrial oils, anti-corrosive oils and cutting oils. It does not contain carcinogenic substances or substances that can be harmful to DNA and fertility and has no danger and safety phrases. Show more
