XJY-8205D MQ Silicone Resin is a polycondensate from four functional group siloxane(Q) and One functional group methyl siloxane(M), the molecular structure of M and Q chain ratio and the structural nature of the M decision resin applications. XJY-8205D is blended with linear polysiloxane and other raw materials to form a silicone polymer with a certain degree of cross-linking. It has a good application effect on defoaming in industries such as printing and dyeing, water treatment, petroleum exploration, and paper making.


Formula suggestion

2%-10% resin addition ratio, dimethyl silicone oil and white carbon black as the main active defoaming ingredients, this formula improves the defoaming performance, improves the defoamer's high temperature resistance, acid and alkali resistance, and improves defoaming The suitability and stability of the agent.



Industrial Utilization


One of the materials of organosilicon defoamer, it acts on the dimethyl silicone oil white carbon black system to improve the defoaming performance, improve the temperature and acid resistance of the defoamer, and maintain the activity of the active ingredients.


1.Improve the high temperature resistance of defoamer.

2.Improve the strong alkali resistance of defoamer.

3.Improve the defoaming performance of defoamer.

4.High-performance silicone defoamer, synthetic silicone grease is recommended to add 8-12% of MQ resin, which significantly improves the antifoam performance of the defoamer;
