BX-MQR-601 Series Methyl MQ silicone resin
Methyl MQ silicone resin has a unique double-layered spherical structure. It offers excellent heat resistance and film-forming properties. The resin also provides strong adhesion and water repellency. It resists aging and UV radiation effectively. This resin serves as a tackifier in silicone adhesives. It is used in construction sealants. It enhances organic resin coatings. It bonds mobile phone buttons securely. It is also added to epoxy adhesives. The 601 series has a more regular molecular structure. It is more structured than the 602 series.
Ⅰ. Product Details
| Model | 601 series methyl MQ silicone resin | ||
| Index | 601P | 601S | 601N |
| Appearance | White Powder | Colorless Transparent Liquid | Colorless transparent viscous liquid |
| Viscosity(25℃) | – | 15-30S (4# cup) | ＞10000 cp [1] |
| Solid content% | ＞99 | 65±2 | ＞99 |
| M/Q value | 0.6-0.9 [2] | 0.6-0.9 [2] | 0.6-0.9 [2] |
| Note: 1. [1] (Viscosity of 601N) and [2] (M/Q value of all models) can be customized according to customer requirements; 2. MQ silicone resin’s “M/Q value” refers to the molar ratio of monofunctional siloxane units (M units, e.g., -Si(CH₃)₃) to tetrafunctional siloxane units (Q units, e.g., -SiO₄/₂)—this ratio directly affects the resin’s hardness, flexibility, and compatibility with other materials; 3. The 601 series has three forms to adapt to different application scenarios: 601P (white powder, high solid content) for high-temperature curing systems; 601S (colorless transparent liquid, medium solid content) for low-viscosity coating/impregnation; 601N (colorless transparent viscous liquid, high solid content) for thick-film coating or adhesive formulations. | |||
Ⅱ. Packaging and Storage
Packed in 25kg cardboard drums or 200kg lined plastic iron drums. Room temperature sealed storage, solution for half a year, powder and silicone oil type for one year. If the storage time exceeds the expiration date indicated on the label, it does not mean that the product cannot continue to be used. But in this case, retesting is necessary.
