Performance and use:
This product is colorless, flammable, insoluble in water, soluble in organic solvents such as benzene, with a viscosity of about 2.1~2.5mm2/s and a freezing point of 0℃~5℃. Under the catalysis of acid and alkali, it can be polymerized into silicone polymer, which is used to produce silicone oil, silicone rubber, etc.

Application：
1. Preparation of a high-transparency high-vinyl methyl vinyl silicone rubber.
2. Preparation of a car cleaning and nursing aldehyde removing sterilizing essence.
3. To prepare a waterproof material for water-based paint surface with high gloss and hydrophobicity.
4. Preparation of a methyl vinyl silicone rubber.

Packaging, storage and transportation：
1. This product is packaged in 210L plastic-lined iron drum or plastic drum (net weight 190㎏/drum) or 1000L steel-plastic square drum, or according to customer requirements and in compliance with safety regulations;
2. The DMC--Dimethylcyclosiloxane should be fireproof, rainproof, moistureproof, and prevent the infiltration of impurities such as acid and alkali during transportation;
3. It is forbidden to use mechanical equipment and tools that are prone to sparks when operating this product; lightly load and unload during handling to avoid leakage of this product caused by container damage.
4. The temperature of the storage site of the DMC--Dimethylcyclosiloxane should be between 20°C and 40°C. When the temperature is lower than 17°C, heat preservation and antifreeze work should be done.
