  • Solid conten>98.5%
  • Product description: Methyl MQ silicone resin for defoamer

Product name :methyl MQ silicone resin for defoamer


Cas no.:56275-01-5

Molecular Structure :


M=[(CH3)3SiO1/2],  Q=[SiO4/2]

The ratio of M:Q and the structural nature of the M decides the special properties and applications.


A kind of Si-O based solid (nonlinearity).

1.Provide excellent transfer resistance and water resistance, form long-lasting form, could be used in defoamer.

2.Has a good application effect on defoaming in industries such as printing and dyeing, water treatment, petroleum exploration, and paper making.

Typical properties:

Appearances:white or light yellow gel solid

Solid content:≥98.5%

M:Q value:0.6-0.8

Molecular weight(g/mol):4000-7000

Bulk density(g/cm3):0.25-0.4


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;

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.
