Silicone Methyl MQ Resin
XJY-8205R for Silicone release agent
Silicone Methyl MQ Resin
Specification
1. PRODUCT FEATURES
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 dimethylsilicone 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.

3. MQ resin-modified silicone release agent has the following characteristics
• Easy to use, high temperature resistant
• Does not cause the molded part to fade
• Can be diluted with solvent
• Silicone release agent has a low surface tension
• In most cases, using silicone release agent can demould in multiple molding cycles after one use. Semi-permanent demolding
• Can form a thermally stable, non-carbonized, non-oily release film
Application
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.
