M Leveling Agent 2 Mercaptobenzimidazole C7H6N2S CAS 583 39 1 White Powder

M, Acid copper intermediate, 2-Mercaptobenzimidazole, leveller

Specifications

Description

1. M can provide brightening deposit which has high degree of leveling and ductility features within a wide range of temperature.
2. M performs well as brightening and leveling agent.
3. M makes it possible to enlarge the brightening scope of deposit and bring the effects of N to the full play.
4. If the content of M is too low, the deposit's leveling and brightness will decline. Low current density areas will not be brightening.
5. 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.
6. M is not suggested in the Dye based acid copper process.

Applications

M can be combined with other acid copper intermediates such as SPS, N, PEG 6000, MT-580, AESS, etc.
M can be applied on the following process:

• Non-dye based bright acid copper for GMF process
• Acid copper for PCB (Printed Circuit Board) process
• Hard copper process
• Acid copper for electrolytic copper foil process

Packing and Storage
