H1 (Tetrahydrothiazolyl thione) applies into Copper Brightening

As one of the main brightening agents, H1 can brighten copper immediately with SP(polysodium dimercaptosulphanate, another main brightening agent used in acid copper plating).It also applies into electric forming and can plate coating as thick as 1 mm within 24 hours.

Recommended usage:
SP: 10 kg/ton brightening agent
H1: 0.5-1kg/ton brightening agent
PNP salt (PN): 10 kg/ton brightening agent
Polyethylene glycol (Mw6000): 8kg/ton brightening agent

Notice: Before being added into brightening agent, it is better to dissolve H1 by water of 80℃.
