Mid-Autumn Festival

Mid-Autumn  Festival  
The festival celebrates three fundamental concepts which are closely tied to one another:
1.gathering, such as family and friends coming together, or harvesting crops
2.thanksgiving, to give thanks for the harvest, or for harmonious unions
3.praying (asking for conceptual or material satisfaction), such as for babies, a spouse, beauty, longevity, or for a good future

Traditions and myths surrounding the festival are formed around these three concepts, although traditions have changed over time due to changes in technology, science, economy, culture, and religion.

Corrosion Inhibitor/Metal Deactivator DMTD/DMCT CAS# 1072-71-5

Corrosion Inhibitor/Metal Deactivator DMTD/DMCT CAS# 1072-71-5

Product Description:

As a thiodiazole derivative, DMTD is an acronym for 2,5-dimercapto-1,3,4-thiodiazole. It is an ashless and multifunctional additive in lubricants, for it not only can work as a corrosion inhibitor and metal deactivator, but also function as an EP/AW agent. So it has found use in coolant, water-based fluids, metalworking fluids and other lubricants. In addition, it is an important chemical intermediate in many industries, such as lubricant, pharmaceutical, rubber and electrochemistry industry for preparation of many other products.

2,5-Dimercapto-1,3,4-thiadiazole (DMTD) has also been used for many years in flame-retardant products. What’s more, it is utilized in a variety of other applications including synthesizing polymers and heavy metal and basic salts in cross linking halogenated polymers in electrode compositions as an intermediate or starting material for pharmaceuticals and dyes as a chelating agent in the analysis of metals in purifying and treating waste and as a biocide.

Application: Coolant, water-base fluids, metalworking fluids Chemical intermediate in lubricant, pharmaceutical and rubber industries.

Recommended treatment level: 0.1 --1.0%  in lubricants or as a chemical intermediate

Packaging: 25KG/Drum  (net weight)
