Key Benefits:

High Purity & Low Volatiles: Features low volatile content (≤0.5% for low viscosity, <1% for mid-viscosity), ensuring minimal shrinkage and bubble-free curing.

Thermal Stability: Maintains physical properties across a wide temperature range (-50°C to +200°C).

Weather Resistance & Durable Protection: Forms a resilient, cross-linked silicone film with exceptional resistance to UV, ozone, moisture, and extreme temperatures, making it suitable for demanding outdoor applications.

Excellent Plasticizing Effect: Acts as an internal plasticizer in elastomers to improve flexibility and elongation.

Versatile Processing: Provides an ideal balance of flowability and mechanical properties for extrusion or pouring.

Electrical Insulation: Offers high dielectric strength for reliable electronic protection.

Applications:

Defoaming Agents: Ideally suited as a base oil for industrial Defoamer formulations. Its optimal viscosity ensures excellent dispersion and rapid defoaming efficiency in non-reactive, harsh environments, such as high-temperature alkaline pulping, textile dyeing, and oil & gas separation, where superior thermal stability is required.

Textile & Leather Finishing: Acts as a highly effective softening and water-repellent agent. Typically applied via emulsion formulation, this viscosity grade imparts a soft, smooth, and durable hydrophobic finish to textiles and leather, significantly enhancing fabric hand-feel and performance.

Electronic Encapsulation & Insulation: Used in formulating potting compounds and insulation paints for PCB assemblies. The low-to-medium viscosity facilitates excellent penetration and wetting, while low volatiles (≤0.5%) ensure bubble-free, low-shrinkage curing for reliable moisture and thermal protection of electrical components.

Specialty Coatings: Serves as a key component in solvent-based or solventless protective industrial and roof coatings. It helps form an elastic, UV-resistant, and weatherproof membrane, providing long-lasting protection for various substrates.
