Application:
Mainly used as brightener for bright copper sulfate. It has good leveling effect. General dosage 0.05 ~ 0.10 g/L. Also can be used as cyanide silver plating as brightening agent, adding 0.5 g/L, the cathode polarization increases, so that the silver ion crystal directional arrangement of bright silver plating layer.
As a universal vulcanization accelerator, the product is widely used in all kinds of rubber. A quick accelerator for natural rubber and synthetic gums usually vulcanized with sulfur. But the use of zinc oxide, fatty acid and other activation. Often used in conjunction with other Chemical book accelerator systems, such as dithiothiuram and tellurium dithiocarbamate as accelerators of butyl adhesive; Used in conjunction with lead trialkylsuccinoleate as a light - colored water - resistant chlorosulfonated polyethylene adhesive.
Rubber accelerator MBT(M).
It is a general accelerator, mainly used in tires, rubber shoes, rubber tape and other rubber products. It cannot be used for rubber products in food packaging because of its bitter taste
