Methyl MQ silicone resin plays a major role in enhancing adhesion and reinforcement in pressure-sensitive adhesives. The silanol or vinyl groups in MQ resin can react with the hydroxyl groups of silicone rubber or with silicone rubber through hydrogen-containing siloxane under the action of a catalyst to produce a silicone pressure-sensitive adhesive.

Using methyl MQ silicone resin in pressure-sensitive adhesives can bring the following benefits:

Improving cohesion: As the amount of silicone resin increases, the cohesion of the pressure-sensitive adhesive increases.
Adjusting peel force: By changing the amount or molecular weight of MQ resin, the peel force of the pressure-sensitive adhesive can be adjusted.
Enhancing adhesion: MQ silicone resin can improve the adhesion of the pressure-sensitive adhesive and make it have better adhesion to the substrate.
Improving high temperature resistance: Methyl MQ silicone resin has good heat resistance and can improve the high temperature resistance of the pressure-sensitive adhesive.

However, when using methyl MQ silicone resin, the following points should be noted:

Dosage control: The amount of silicone resin affects the performance of the pressure-sensitive adhesive and needs to be adjusted according to specific needs.
Molecular weight selection: MQ resins of different molecular weights also have different performance on pressure-sensitive adhesives, so it is necessary to select the appropriate molecular weight.
Compatibility with other ingredients: Ensure that methyl MQ silicone resin has good compatibility with other ingredients in the pressure-sensitive adhesive to obtain stable performance.
