PN 1. PN is a kind of high molecular polymer which needs to be used in combination with SP, M, N, P, AESS or GISS. 2. It is powerful in cathodic polarization and remarkably elevates the brightening degree in LCD areas. When the brightening degree is not high enough, HCD agent (Poly dithio) could be added accordingly. 3. PN is the best high-temperature carrier in acid copper brightener. It is suitable for complex plating pieces. 4. Widely used within the temperature between 15-45℃, PN is appropriate for both acid copper and non-cyanide zinc plating brightener. |

PNI 1. PNI is the intermediate similar as PPNI. Directing to the feature that dye-based brightener could not resistant high temperature, PNI reflects its fine leveling feature in high, middle and low current density areas. 2. It is the high-temperature carrier for acid copper brightener. The temperature of the baths could be as high as 40℃. |

H1 1. The uses of H1 are similar to M and N. It is always utilized in combination with SP, PN, P or GISS, and performs well in leveling. 2. If the content of H1 in baths is too low, the brightening and leveling features will decline. If it is too high, dendritic brightening stripes will appear. This could be solved by adding SP or electrolyzing the solution. |

PPNI 1. PPNI has powers of fast brightening and good leveling in all current density areas, and will not make hydrophobic film on plating parts. 2. It can help maximize the working temperature range of baths. 3. It could be added to baths individually or together with dyes. 4. PPNI is not used in combination with SPS or SP. |
