M 2 Mercaptobenzimidazole Acid Copper Intermediate

Catalog Number	ACEP583391-2
CAS	583-39-1
Structure
Description	M can provide brightening deposit which has high degree of leveling and ductility features within a wide range of temperature. M performs well as brightening and leveling agent. M makes it possible to enlarge the brightening scope of deposit and bring the effects of N to the full play. If the content of M is too low, the deposit's leveling and brightness will decline. Low current density areas will not be brightening. If the content of M is too high, pitting or even orange peel or burning will appear at the surface of deposit. The thickness of the deposit at the HCD areas will decrease, and then a small amount of P or SP could be added or using electrolysis to solve the problems. M is not suggested in the Dye based acid copper process.
