The acidic copper plating additive M (2-thiobenzimidazole) can be plated with good flatness and toughness in the temperature range of 10 to 40 ℃. M is a good brightener and leveling agent, and can also expand the bright range of the coating, especially the brightness effect of the low current ... Read More

PEI polyethyleneimine is a high polarity and high density polyamine compound with primary, secondary and tertiary amine branching structure. Due to its structural properties, it becomes a water-soluble polymer with wide reactive properties. In order to impart various functions to the plastic film, ... Read More

Commonly used chemical sand-fixing materials include:water glass, cement slurry, petroleum products, and high-absorbent resin. Existing chemical sand-fixing agents clay, although they have the effect of sand-fixing, will form a crust on the surface of the sand-fixing layer, which hinders the ... Read More

Electroplating is the process covering a thin layer of metal on the surface of a metal by electrochemical means, so that the deposited metal and the substrate metal produce a firm bond, in order to achieve the of rust prevention, wear resistance, dimension repair and decoration. Its essence is to ... Read More
