Methyl MQ resin is formed by polymerization of tetrafunctional siloxane (Q) and monofunctional methyl siloxane (M). It is widely used in the fields of personal care, adhesives, defoamers, waterproofing agents, etc., and has a good application effect in the fields of high temperature, semi-permanent, or permanent for the silicone release agent.

In the silicone release agent formula, polydimethylsiloxane is widely used, and a certain amount of MQ silicone resin is added to it. After being coated on the surface of the mold at high temperature, some hydroxyl groups on MQ resin will be condensed to form a reinforcing filling for film formation of dimethyl silicone oil, thus increasing the use temperature of the release agent and increasing the reuse times, thus improving the production efficiency of downstream customers and reducing the production cost.

Silicone release agents have the characteristics of high and low-temperature resistance, low surface tension, and no corrosion to metals. Adding MQ silicone resin (5-15%) can significantly increase the strength of silicone oil film, and has good application effects in high-temperature castings, tire demoulding, car seat cushions, and other fields.


Remarks: Jiangxi New Jiayi New Material Co., Ltd. is currently conducting a pilot test of water-based resin for silicone release agents and has made good progress. By grafting hydrophilic groups on the resin, it has realized that no additional emulsifier is added and no mechanical emulsification is required for water. The purpose of decentralization. In the application field of water-based silicone release agents, the adverse effects of beneficial emulsifiers on the mold release process can be avoided.


Silicone release agents have the characteristics of high and low temperature resistance, low surfacetension, and non-corrosion to metals. Adding silicone resin (5-15%) can significantly improve thestrength of the silicone oil film, and has good application effects in high-temperature casting, tirerelease. automotive seat cushions, and other fields.

What is the role of MQ resin in silicone release agents?

MQ resin, as the structural body of the mold release agent, is able to condense the active hydroxyl group under thermal curing and cure into a film, providing semi-permanent characteristics to the mold release agent system and slowing down the migration of Dimethicone to achieve repeated mold release.

What is the significance of water-based mold release agents in silicone mold release agents?

Water-based release agent is actually emulsified release agent components and dissolved in water, the purpose is to reduce VOC emissions, more environmentally friendly. At the same time, when dissolved in water, the viscosity of the system will be greatly reduced, which is convenient for customers to spray and use when releasing the mold.
