PEG-12 dimethicone Performance characteristics
This product is a kind of organosilicon nonionic surfactant with unique performance which is made by grafting and copolymerizing polyether and polydimethylsiloxane. Compared with traditional hydrocarbon surfactants, this organosilicon surfactant Has the following characteristics:
1. Low surface tension.
2. Good lubricity and wear resistance.
3. Good antistatic and thermal stability.
In addition, compared with polydimethylsiloxane, this material can be dispersed in water, is also miscible with polar organic solvents such as alcohol, DMF, ether, ester, etc., and is partially or completely compatible with non-polar solvents such as alkanes.
PEG-12 dimethicone Application:
1. Leveling agent for synthetic leather coating;
2. Make the synthetic coating have anti-blocking, lubricity, wear resistance and improve its scratch resistance;
3. Improve the defoaming and anti-foaming properties of defoamers;
4. Used in the manufacture and processing of yarns and fibers, providing lubricity, thermal stability, and antistatic properties.
PEG-12 dimethicone Dosage
1. Used in the synthetic leather system, directly added to the slurry, the recommended addition amount is 0.2-0.5%;
2. When making the finishing agent, add water directly and stir well after dispersion. If stratification occurs, high-shear equipment such as a homogenizer can be used.
PEG-12 dimethicone Precautions
There may be pressure in the package. It is forbidden to open it suddenly, and the lid should be opened after slowly releasing the pressure. It is forbidden to face workers, electrical equipment, and fire sources. It cannot be mixed with strong acids and strong alkaline substances. It is stable under the system of PH=5, otherwise, it is easy to produce free hydrogen and cause an explosion. It is advisable to use adequate ventilation and exhaust equipment, avoid eye contact, do not take it internally, and implement good industrial hygiene measures. Please wash after an operation, especially before eating, drinking, and smoking. For a long time at a high temperature above 160 degrees Celsius or mixed with acid and alkali substances, the viscosity will increase or even cross-linking.
PEG-12 dimethicone Packaging and storage
1. Packaging: This product is packed in a 50kg plastic drum and a 200kg galvanized iron drum.
2. Storage: Store in a dry, cool place, avoid contact with strong acids and alkalis.
3. Transportation: This product is transported as non-dangerous goods.
