Product name:Methyl MQ silicone resin for addition cure PSA

Model:NV-MQ930

Cas no.:68988-56-7

Molecular Structure :

[(CH3)3SiO1/2]a[SiO4/2]b

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.

Discription:

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.

Benefits:

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.
