  • To prevent the Loctite 243 from clogging in the nozzle, avoid tip and metal surface get in contact during application

  • Store in dry location

How to clean Loctite 243 after using?


It could be removed with a combination of soaking in a solvent and wire brush.

Where can you use Loctite 243?


It works on active metals such as brass or copper as well as on passive substrates ie. stainless steel and plated surfaces.

It is proven to be tolerant of minor contamination due to industrial oils, e.g. engine oils, corrosion prevention oils and cutting fluids.

Benefits


  • Prevents loosening on vibrating assemblies, e.g. pumps, gear boxes or presses

  • Works on all metals, including passive substrates (e.g. stainless steel, aluminium, plated surfaces)
