Pilcure SDBC is an ultra fast water soluble dithiocarbamate accelerator which can vulcanize NR, SBR, NBR, latex based compounds even at room temperature. Pilcure SDBC is suitable for all vulcanization methods used in the latex goods manufacturing technology.

Pilcure SDBC is very active above 90°C – 100°C and activates cure systems based on ZDC, ZDBC, ZMBT and MBT in NR/SR latex compounds in the presence of zinc oxide.

As a primary accelerator, Pilcure SDBC is used at 1.0-3.0 phr dosage in latex compounds based on NR, SBR, NBR, lattices to initiate vulcanization from 90°C - 100°C. As a booster accelerator the dosage of Pilcure SDBC is in the range of 0.25-0.75 phr.  Due to its faster activation rate, the Pilcure SDBC based / boosted latex compounds exhibit rapid increase in viscosity and   have a limited shelf life.  

Although, Pilcure SDBC alone can also vulcanize latex compounds, the vulcanizates do not attain high degree of cure and hence Pilcure SDBC is generally used as a booster accelerator. 

Pilcure SDBC boosted vulcanizates offer good resistance to heat aging without any discoloration and the vulcanizates are practically odorless and tasteless.

The rate of vulcanization of Pilcure SDBC can be boosted with small proportions of thiazole, thiuram and guanidine accelerators and can be retarded by 2- mercaptobenzimidazole.

The vulcanization temperature in excess of 125°C should be avoided to prevent over cure effects on the vulcanizates. 

Pilcure SDBC is also suitable for vulcanization of thin-walled dry rubber based products in hot water.

Pilcure SDBC can be diluted with water to appropriate concentration before addition into latex compound. Aqueous solutions of Pilcure SDBC have good storage stability; however, the solubility of solid contents in Pilcure SDBC deteriorates after some time and a freshly prepared solution appears slightly turbid.  This turbidity generally does not affect the efficiency of Pilcure SDBC.

It is recommended to store Pilcure SDBC in a cool and dry place in the form of aqueous solution to ensure its stability. Pilcure SDBC should not be allowed to freeze and solidify.

 Pilcure SDBC can be used for the production of latex dipped products, transparent / light colored products.
