Applications

MBT biocide is an efficient, broad-spectrum germicide and algaecide. It features strong extermination effects against germs, fungus, and algae existing in circulating water. MBT maintains long-term effects and is applicable to broad pH value and temperature ranges. Using 3-4 ppm MBT kills over 90% of nitrosation germs, sulfate-reducing germs, colon bacillus, anti-nitrosation germs and many other types of germs. MBT liquid is stable, and Methylene Bis(Thiocyanate) can decompose shortly in the application. MBT has an analysis method and is easy for monitoring, so it is safe for discharge.

Methylene Bis(Thiocyanate)can increase oil production by reducing oil layer contamination, preventing clay form expanding, and disinfecting. This MBT chemical can also be used to protect packing paper from going molding, treat circulating cooling water, and remove marine organisms from marine liners. It has excellent effects of anti-corrosion, germicide, and algaecide for electrical materials, bamboo, and woodenware, coatings, rubber, canvas, glue, and ink.

MBT 1% emulsion is a kind of efficient, broad-spectrum and safe agricultural germicide, having good effects against diseases of rice and wheat.

Within the recommended quantity, Methylene Bis(Thiocyanate) is safe to rice seed and increases germination percentage. As MBT is an organic thiocyanic germicide, it can solve the problem of anti-pesticide property developed by the widely used absorbing germicides.

When used in treating rice seed, MBT does not need presoaking or after-washing. MBT biocide can be used directly in germination and seeding.

Methylene Bis(Thiocyanate) also can be made of safe fish medicine to prevent many kinds of fish diseases. MBT is a good disinfectant in the water for various breed aquatics.
