| Physical and Chemical Properties | Chemical Properties This product is an emulsion of silicone resin. The appearance is milky white paste. Dissolve in hot water. Non-toxic. Tasteless. |
| Use | Uses this product is used for soft processing of cotton, wool, silk, hemp and synthetic fiber. It can be used in the same bath as the fluorescent whitening agent VBL. |
When using, gloves and protective glasses should be worn to avoid direct contact with the skin and eyes. If it gets on the skin, rinse with water and soap. Place in a cool and dry warehouse to prevent exposure to sunlight and rain.
80 parts of organic silicone oil D4, 600 parts of water, 3-5 parts of sodium dodecylbenzenesulfonate, 25 parts of penetrating agent JFC, 40 parts of flat and 0, and 20 parts of urea were successively put into the reaction kettle, and quickly stirred for emulsification. Heat up to 80 ℃, hold for 2 hours, and allow for ring opening polymerization. Then cool to room temperature and continue stirring for 5-6 hours to increase the molecular weight of the silicone resin. The average molecular weight reaches 200000 as the endpoint. Finally, neutralize with pure alkali solution to a pH value of 6.5-7.0, discharge while hot, and package to obtain the finished product. Among them, octamethylcyclotetrasiloxane undergoes ring opening polymerization to form polydimethylsiloxane.
80 parts of silicone oil D4,600 parts of water, 3-5 parts of sodium dodecyl benzene sulfonate, 25 parts of penetrant JFC,40 parts of flat plus o and 20 parts of urea were successively put into the reaction kettle for rapid stirring and emulsification. Heat the temperature to 80 ℃, keep the temperature for 2 h, and make the ring-opening polymerization. Then cool to room temperature and continue stirring for 5~6 h to improve the relative molecular mass of silicone resin. The average relative molecular mass reaches 200,000 as the end point. Finally, neutralize with soda ash solution to pH = 6.5~7.0, discharge while hot, and package to obtain the finished product. Among them, octamethylcyclotetrasiloxane is cyclically polymerized to synthesize polydimethylsiloxane.
