Wholesale price from a methyl MQ silicone resin manufacturer
Release Date:
2020-11-04
A white or pale yellow powder, with an M:Q ratio of 0.6–0.9:1. It exhibits excellent heat and low‑temperature resistance, moderate flexibility, good film‑forming properties, water repellency, favorable adhesion, and superior release characteristics. It can be used to formulate high‑temperature‑resistant coatings, water‑repellent agents, mold release agents, tackifiers for pressure‑sensitive adhesives, reinforcing agents for silicone rubbers, defoamers, epoxy adhesives, and more.
[Performance Features]
Methyl MQ‑type silicone resin is a novel organosilicon material characterized by a three‑dimensional (nonlinear) molecular structure with a Si–O backbone. Its structural formula is: [(CH3)3SiO1/2]a[SiO4/2]b, where [(CH3)3SiO1/2] corresponds to the M unit and [SiO4/2] corresponds to the Q unit. Depending on the M:Q ratio, its properties, specifications, and applications vary accordingly.
Methyl MQ-type silicone resin possesses the following excellent properties:
1. Excellent heat resistance and low-temperature performance, enabling use in environments ranging from -60°C to +300°C.
2. Excellent film-forming properties, moderate flexibility, and outstanding aging resistance and UV‑radiation resistance.
3. Excellent water repellency.
4. Good adhesion performance.
5. It offers excellent release performance and long-lasting durability, making it a semi-permanent mold release agent.
[Technical Indicators]
1. Appearance: White or pale yellow powder
2. Solid content: ≥99%
3. M:Q ratio: 0.6–0.9:1
4. Softening point: 160–260°C
5. Molar mass: approximately 400,000
[Purpose]
1. Formulate high-temperature-resistant coatings for insulation, bonding, and sealing in Class H motors.
2. Used to formulate various waterproof coatings and serves as an ideal ingredient in the daily‑chemical industry for manufacturing lipsticks and other products.
3. Suitable as a adhesion promoter in the bonding and composite of inorganic and organic materials.
4. Can be used to formulate release agents for a wide range of materials.
5. It improves and modulates the peel adhesion of pressure-sensitive adhesives, thus serving as a peel‑force modifier in the production of pressure‑sensitive tapes and similar products.
6. Used as a reinforcing agent in silicone rubber, the resulting reinforced silicone rubber is colorless and transparent with high mechanical strength.
7. Used for Defoamer During the manufacturing process, a specific MQ value can undergo crosslinking without requiring solvent dilution or dissolution. [Usage and Dosage]
[Packaging, Storage, and Transportation]
The product shall be stored and transported as a non-hazardous material.
