lDOWELLLIT FMC is a safe, low-toxicity, economical and efficient bactericide.

lDOWELLIT FMC has complete compatibility with stability to hard water. It is compatible with DOWELLZYM series of enzymes, common soaking and liming materials.

lDOWELLIT FMC has a strong function of inhibiting the reproduction of bacteria in the pH 7-12.


lDOWELLIT FMC inhibits the reproduction of bacteria in the long-time soaking and enzyme unhairing process. It can also be used for the short-term preservation of raw hides and skins.

lThe dosage of DOWELLIT FMC depends on the ambient temperature, time and the condition of raw hides and skins. At 25℃, the reproduction of most bacteria can be controlled by adding 0.1 % DOWELLIT FMC into the float.

lRecommended amounts (based on wet-salted weight of hides and skins):

Soaking: Rapid soaking (4-6 hours) 0.05%-0.10%.

Normal soaking (less than 24 hours) 0.15%-0.40%.

Enzyme unhairing, enzyme coating and alkali coating: add 0.1%- 0.15% DOWELLIT FMC without water, run 30 minutes and then unload.

lAll the above dosages are recommended at 20. It is suggested to increase the dosage of DOWELLIT FMC if the temperature is increased. Generally the amount of DOWELLIT FMC should be increased by 30% if the temperature is up by 5°C. The percentage of DOWELLIT FMC should be increased according to the amount of water used in the process. The final dosage of this product should be determined by prior testing according to the actual conditions.
