Additives for electroless tin plating

Sn-871 is a new environmental protection chemical tin sinking process,which has the characteristics of stable performance,convenient operation and economy. Compared with the traditional inorganic tin leaching,the tin deposition rate is faster,the performance is more reliable,and it is not easy to produce tin whiskers,and the solderability of the tin layer obtained is good.

Product Description

Product Name: Chemical tin additive Packing specification: 25kg/barrel
Product appearance: Clear and transparent liquid Odor: Mild
Specific gravity: 1.10-1.12 Solubility in water: all dissolved
Storage: ventilated and dry place Shelf life: 2 years

Instructions for use

Chemical tin additives

Original solution use




5-30 minutes (depending on needs)

Working load

1-2dm²/L (that is,the plating area carried by 1 liter of working fluid)


Mechanical stirring


Continuous filtration,the filtration volume per hour is not less than 6 times the working fluid capacity

Plating tank material

PP plastic or FRP

Solution maintenance

1.Use chemical immersion tin additives to supplement the loss.

2.The copper impurities in the plating solution will hinder the reduction of tin,and control it to less than 5 g/l. It can be electrolyzed by a small current to make copper precipitate and remove at the cathode
