1. Chemical Name:
Acrylate Modified Polymethylethylsiloxane

2. Technical Indicators:

• Appearance: Colorless, odorless, transparent liquid

• Viscosity at 25°C: 200–500 CST

• Density: 0.92–0.94 g/cm³

• Flash Point: >180°C

• Freezing Point: < -75°C

3. Performance and Uses:

• Functional Groups: The product is an acryloxypropyl-modified methylethyl silicone oil. The content of acryloxypropyl functional groups can be customized to meet specific user requirements.

• Low-Temperature Performance: The polymethylethylsiloxane backbone exhibits a glass transition temperature (Tg) as low as -143°C, ensuring exceptional flexibility and stability in extreme cold conditions. This makes it suitable for applications in aerospace, polar equipment, and low-temperature lubricants.

• Chemical Stability: It demonstrates outstanding resistance to most chemicals, including strong acids and alkalis. However, it may react with concentrated sulfuric acid and hydrofluoric acid.

• Versatile Applications:

  • Coatings and Adhesives: The acrylate groups enable UV or thermal curing, making it ideal for durable coatings, inks, and adhesives with enhanced adhesion, scratch resistance, and water repellency.

  • Industrial Lubricants & Sealants: With its wide operational temperature range (from below -75°C to high temperatures), it serves as a reliable lubricant or sealing material in automotive, machinery, and cryogenic systems.

  • Textiles and Plastics: Used as a surface modifier to provide water/oil resistance and anti-fouling properties without relying on hazardous fluorinated compounds.

  • Electronics: Its insulating properties and stability make it suitable for encapsulating electronic components or as a dielectric material.
