Bonds:
Resin bond: phenol-formaldehyde,  does not require lubricant, but you may use water (or water based cooling liquids)
Metal bond: M2-01, copper-tin

Preparation of sharpening stones
These stones require preparation (dressing), or they will be self-polished after sharpening of 30-50 knives. Then they will be of gold color and work well.
This is common issue for all manufacturers: abrasive grains are covered with bond, so you need to “release” them.
