Methylene Bis Thiocyanate maintains long-term effects and is applicable to broad pH value and temperature ranges. Using 3-4 ppm,  it can kill over 90% of nitrosation germs, sulfate-reducing germs, colon bacillus, anti-nitrosation germs and many other types of germs. Methylene Bis Thiocyanate liquid is stable, and Methylene Bis Thiocyanate can decompose shortly in the application. It has an analysis method and is easy for monitoring, so it is safe for discharge.

The MBT biocide can increase oil production by reducing oil layer contamination, preventing clay from 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, has good effects against diseases of rice and wheat.

About methylene bis thiocyanate uses. Within the recommended quantity, Methylene Bis Thiocyanate wiki is safe for rice seeds and increases germination percentage. As MBT is an organic thiocyanic germicide, it can solve the problem of anti-pesticide properties developed by the widely used absorbing germicides.

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

The MBT also can be made of safe fish medicine to prevent many kinds of fish diseases. MBT biocide is a good disinfectant in the water for various breed aquatics.

  • Control of microbial activity in cooling water systems.
  • Control of slime in Pulp & Paper Manufacturing.
  • Preservation of paints, adhesives, synthetic polymer lattices and latex emulsions.

About methylene bis thiocyanate toxicity. The biocide is very toxic to aquatic organisms. Avoid release to the environment in circumstances different to normal use. When heated to decomposition, MBT emits very toxic fumes of NOx and SOx.

Packing and Storage:

Normally packed in 25kg/paper bag or fiber drum, also be packed as required.

Stored in cool, dry and ventilative places. Keep away from incompatible substance. MBT chemical can not be stored together with food and feedstuff.
