Introduction Name:Ammonium Sulphate CAS No.:7783-20-2 Formula:(NH4)2SO4 Apperance:Crystal N:21% S:24% Application Ammonium sulfate plays a beneficial role in neutral electroplating (electroplating except for strong acid and alkali), such as stabilizing bath solution,refining coating crystallization,and preventing coating brittleness. 1.Auxiliary complexation Ammonium sulfate actually plays an auxiliary role in the cathodic process as a bridge for the smooth deposition of metals. 2.PH buffer As a result of hydrogen evolution in the cathode process,the pH value of the cathode surface increases continuously. Therefore, pH buffer must be added to all neutral electroplating tanks. These buffers, such as boric acid, acetate and other weak acid and weak base salts, usually complete the buffering function because the ionized H+ions migrate to the cathode surface and neutralize the OH- ions increased due to H2 evolution, generating water that is difficult to ionize. In addition to completing this function, ammonium sulfate also complexed the free metal M2+ion, so as to improve the polarization of the metal ion on the cathode and refine the crystal structure. 3.Conductivity of reactor fluid Ammonium sulfate has good conductivity. Its addition will effectively expand the application range of cathode current density and improve the dispersion ability of the bath.

Iodophor Ingredients: Iodine, dimethyl dodecyl amine oxide, quaternary ammonium salt, non-ionic surfactant, etc. Raw Material Assay: Iodine 5% The common name of the preparations: Iodine trioxide Administration & Dosage of the Preparations: Iodine 3%. Characterization Appearance and usage Reddish brown sticky liquid; its aqueous solution is acidic, foams produce when shaken. It is easily soluble in water or ethanol. It can be dissociated into cationic active species with reactive oxygen and active iodine in the aqueous solution, which has cleaning function. Pharmacological effects It is the complex compound of four alkyl amine reactive oxygen species and iodine, added the special synergist. It is stable and has no impurity. Precautions The preparations wrappers: should be fitted with brand new dark PET/HDPE with plastic inner lid. The Process of making preparations: when you fill the dilution into the container, the foam will be produced. Therefore, the self-priming filling machine is not appropriate. Please be attention the requirement of the preparation's pH value. The requirement of water quality: deionized water would be best. Don't make it with the high hardness tap-water and alkaline water.
