2000 molecular weight methyl MQ silicone resin is a methyl-type MQ silicone resin composed of monofunctional M and tetrafunctional Q segments. It has a moderate molecular weight, good solubility, and excellent compatibility. It possesses good reinforcing, tackifying, film-forming, hydrophobic, high and low temperature resistance, and aging resistance properties. It has good compatibility with dimethyl silicone oil, various silicone rubbers, and organic resin systems, making it a widely used functional resin in silicone materials.
In the field of silicone pressure-sensitive adhesives, 2000 molecular weight methyl MQ silicone resin serves as a core tackifying and reinforcing component. It can be compounded with 107 adhesive, high-viscosity silicone oil, etc., to prepare high-performance silicone pressure-sensitive adhesives, significantly improving the initial tack, holding power, and peel strength of the pressure-sensitive adhesive. It imparts excellent high and low temperature resistance, weather resistance, and aging resistance to the adhesive layer. It is widely used in high-temperature silicone tapes, PI high-temperature resistant tapes, double-sided silicone pressure-sensitive adhesives, electronic insulating tapes, die-cut tapes, and other products, achieving stable and reliable adhesion to various substrates.
In the field of silicone rubber reinforcement, it can be used as a reinforcing resin for high-temperature vulcanized silicone rubber and liquid silicone rubber, effectively improving the tensile strength, tear strength, hardness, and heat resistance of silicone rubber, while maintaining the transparency and surface smoothness of the finished product. It is easy to disperse and has good processing fluidity, making it suitable for transparent silicone products, seals, buttons, medical-grade silicone products, and high-temperature resistant silicone components. The reinforcement effect is balanced and does not affect the vulcanization process.
In electronic adhesives and potting materials, adding this MQ resin can enhance the adhesive strength, mechanical properties, and insulation properties of silicone electronic adhesives, potting compounds, and sealants. It improves the colloid's resistance to moisture and heat, as well as its moisture and dust resistance, making it suitable for potting and bonding electronic components, PCB circuit boards, sensors, LED modules, and precision electronic components, ensuring the long-term stable operation of electronic components.
In the field of high-temperature coatings and protective coatings, as a film-forming component and functional additive, it can be used to prepare high-temperature resistant, weather-resistant, and hydrophobic protective coatings, improving the adhesion of the coating to substrates such as metals, glass, and ceramics, and enhancing the coating's heat resistance, stain resistance, aging resistance, and insulation properties. It is suitable for high-temperature anti-corrosion coatings, electrical insulation coatings, industrial protective coatings, and hydrophobic dustproof coatings.
In terms of mold release agents and surface treatment agents, it can improve the film-forming properties and durability of mold release agents, making it suitable for efficient demolding of rubber, plastics, polyurethane, and other products without contaminating the mold or product surface. It can also be used as a material surface treatment agent, forming a stable hydrophobic film on the substrate surface, providing dustproof, weather-resistant, and protective functions.
In silicone sealants and insulating materials, adding 2000 molecular weight methyl MQ silicone resin can improve the sealant's colloidal strength, water resistance, and insulation properties, enhancing sealing durability and high/low temperature resistance. It is suitable for building sealing, industrial sealing, electrical insulation sealing, and other applications, meeting long-term stable sealing and insulation requirements.
