Nitroguanidine application in phosphating agents for metal surface treatment

Metals, specifically steel, are often coated with a phosphate layer for protection against corrosion. This is widely used for car bodies in the automobile industry.Nitroguanidine is an excellent accelerator in the acidic phosphating agent baths.The mode of action stems from its oxidation potential. Nitroguanidine acts as a depolariser, which leads to a faster and better buildup of the phosphate layer.

Butyronitrile is used not only as an intermediate in the pharmaceutical, veterinary or agrochemical industry, it also serves as dipolar aprotic substitute for acetonitrile in a wide temperature range.

2-Sodium-hydroxy-4,6-dichloro-1,3,5-triazine (NHDT)

AlzChem has long-standing experience in many fields of organic synthetic chemistry such as Triazines. We proudly announce 25 years of experience in producing 2-Sodium-hydroxy-4,6-dichloro-1,3,5-triazine in aqueous solution. After that long period the process is well-established and over 10.000 mt have been produced in total. AlzChem–NHDT stands for optimized quality as well as highest stability. NHDT is mainly used as crosslinker in the textile industry and for hardening of gelatine in photo-applications.

Is Silicon Chemistry Compatible With Carbon? – We Know How

Silicon belongs to the same main group in the periodic table of elements as carbon.
However there are some essential differences in the chemistry of both elements.
AlzChem has long experience with silicon chemistry. We are active in inorganic products like silicon nitride and organic derivatives like silanes.
For the most part we cooperate with customers in exclusive projects, therefore please contact us, if you look for a molecule containing a Si-C bond.
