Methyl MQ silicone resin for Addition Cure PSA

  • Model:NV-MQ930
  • Cas no.:68988-56-7
  • Sodium silicate method
  • Addition cure PSA
  • Product description: Silicone resin,used for addition cure silicone pressure sensitive adhesive and defoamers.

Product name:Methyl MQ silicone resin for addition cure PSA


Cas no.:68988-56-7

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.


It is the co-hydrolysate of tetra-alkoxysilane (Q unit) and trimethylethoxysilane (M unit).

It can be regarded as a 3D network structure of polysilicate terminated by trimethylsilane group, containing some ethoxyl and hydroxyl functional groups.

It is prepared by sodium silicate method.


1.In PSA industry:

To improve the cohesive strength of silicone pressure sensitive adhesive and adjust the peeling force.

2.In the field of defoamer:

To improve effectively the high temperature resistance, defoaming and foam inhibition.

3.In the field of release agent:

It is a release agent with high efficiency and high compatibility.

Typical properties:

Appearances:white or light yellow gel solid

M:Q value:0.6-0.8

Molecular weight(g/mol):4000-6000

Bulk density(g/cm3):0.25-0.40

Average particle size( μ m): 100

Hydroxy content(%)≤0.5


1.Used in addition cure pressure sensitive adhesive and transparent reinforcing filler.

2. Used in defoamer and antifoaming agent.

3. Used in release / demoulding agent.
