The application of methyl MQ silicone resin emulsion in the mold release industry is mainly due to its unique molecular structure and excellent performance characteristics. The following describes in detail its mechanism of action, application advantages, and typical application scenarios.：


Mechanism of action
Methyl MQ silicone resin emulsion is made of silicate and hexamethyldisiloxane or trimethylsilanol by emulsion polycondensation reaction. It has a three-dimensional spherical three-dimensional mesh structure, the core is a high-density cage-like SiO₂, and the outer layer is covered with a low-density methylsiloxane layer.This structure gives it excellent heat resistance, low temperature resistance, flexibility and film-forming properties, while the methyl group gives it good hydrophobicity and isolation.During the mold release process, the emulsion can form a uniform and dense silicone oil film on the surface of the mold. The film has the characteristics of low surface tension, which can effectively reduce the adhesion between the mold and the product and achieve easy mold release.


Application advantage
Improve the durability of mold release: Adding methyl MQ silicone resin emulsion to the mold release agent can significantly improve the strength of the silicone oil film, increase the temperature of the mold release agent, and increase the number of reuses, thereby improving production efficiency and reducing production costs.For example, in the fields of release of PU soles, tires and auto parts, the release agent of methyl MQ silicone resin emulsion can be added to achieve semi-permanent release, and it can play a role in multiple molding cycles after one use.
Improve the release effect: Methyl MQ silicone resin emulsion has a more ideal release effect on highly adhesive resins (such as polyurethane, epoxy resin, etc.), which can avoid damage to the product during the release process and improve the product pass rate.
Environmental protection and safety: Methyl MQ silicone resin emulsion can achieve water dispersion by grafting hydrophilic groups on the resin, avoiding the addition of emulsifiers, reducing the adverse effects on the mold release process, and reducing environmental pollution.
Typical application scenarios
Methyl MQ silicone resin emulsion has a wide range of application scenarios in the mold release industry, including plastics, rubber products and metal casting.For example, in the production of plastic products, methyl MQ silicone resin emulsion mold release agent can effectively prevent the product from sticking to the mold and improve production efficiency; in the production of rubber products, its excellent high temperature resistance can ensure that the mold release agent remains stable during high temperature vulcanization and high-quality mold release is achieved.
