Methyl MQ Silicone Resin
Specification
PRODUCT FEATURES
Product name：Methyl MQ resin（Silicic acid, sodium salt, reaction products with chlorotrimethylsilane and iso-Pr alc.）
Cas No. 68988-56-7
Methyl MQ silicone 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 release agents.
In the 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 silicone 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.

Application
Silicone mold 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 Xinjiayi New Material Co., Ltd. is currently conducting a pilot test of water-based resin 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 mold release agents, the adverse effects of beneficial emulsifiers on the mold release process can be avoided.
MQ resin modified release agent has the following characteristics
• Easy to use, high temperature resistant
• Will not cause the molded part to fade
• Can be diluted with solvent
• Has low surface tension
• In most cases, it can be demolded in multiple molding cycles after one use. Semi-permanent demolding
• Can form a thermally stable, non-carbonized, non-oily release film
