Acid copper plating additive 2-mercaptothiazoline

Acid copper plating additive 2-mercaptothiazoline (H1) has high brightness and leveling capabilities when operating at 20 ~ 25 ℃, but does not obtain copper plating with good brightness and leveling performance when operating at above 30 ℃.

2-mercaptothiazoline (H1) affects the growth of copper crystals through adsorption, making the copper plating grains significantly refined. At the same time, due to strong characteristics of adsorption, the chances of it being interspersed on the crystallization surface increase, and the stress of the coating increases. In addition, since the adsorption of 2-mercaptothiazoline (H1) is controlled by diffusion, it has a positive leveling effect.

Wuhan Bright can supply H1 (2-mercaptothiazoline) ‍, the product is stable in quality, excellent in performance and reasonable in price.
