TPP TPP

1. In acid nickel plating bath, if the copper ion >10mg/L and zinc ion>20mg/L, dark-grey deposit will emerge in LCD areas, embrittlement increased, or even black stripes could be produced. Directing to this problem, electrolytic treatment is implemented to deal with the zinc ions, QT (copper-remover) is used to remove copper ion traditionally. However, the above mentioned method is too comprehensive and time-consuming, it may affect the production. TPP will alter the potential of copper impurity and zinc impurity, and subsides the impurities without electrolyzing or filtering the baths. Meanwhile, deposit brightness is increased, nickel yellow stains are eliminated, and covering power is improved. TPP is especially used for zinc alloy die-casting nickel plating bath to remove impurities.
2. Utilization method: dissolve 1kg solid TPP into 100kg deionized water and add 2-4ml/L into baths, it may remove copper 15mg/L and zinc 20mg/L.
MASS MASS

1. MASS is the top-grade glossy black and sulfur-free leveling agent.
2. Proper amount of MASS could remarkably improve the leveling power and brightening speed. The deposit will be glossy, chunky, non-haze and no rust points. MASS also has good throwing power, and can eliminate the leak plating.
3. It fits into compounding rolling barrel plating, rack plating and half-brightening nickel plating agents. When used in combination with saccharin and alkynol, the deposit will be extremely glossy black, clear and even.
PAP PAP

1. PAP, the condensation substance of propiolic alcohol and propylene oxide, is one of the most common components of nickel plating brighteners.
2. As the leveling and high-speed brightening agent, it is normally used in conjunction with BMP, PPS, PVSS, COSS, PESS, MOSS or other auxiliary agent.
PME PME

1. PAP, the condensation substance of propiolic alcohol and ethylene oxide, is one of the most common components of nickel plating brighteners.
2. As the leveling and high-speed brightening agent, it is normally used in conjunction with BEO, PPS, PVSS, COSS, PESS, MOSS or other auxiliary agent.
BEO BEO

1. BEO, the condensation substance of butynediol and ethylene oxide, is one of the most common grain refining components of nickel plating brighteners.
2. It is normally used in conjunction with PME, PPS, PVSS, COSS, PESS, MOSS or other auxiliary agent.
