Hamico® 863-EP Base is normally used as received, but can be diluted with oil, solvents, or water, depending on the operation. It may be applied by dipping, spray, or brushing. It is a combination of extreme pressure lubricants. It is used either neat or with oil. It is used primarily for tapping operations on steel. It will not corrode steel or aluminum on contact, but will stain brass and copper.
