Features: High hydroxyl content, short molecular chain, extremely high reactivity.

Specifications:

Key Benefits:

High Reactivity: High hydroxyl content ensures rapid and efficient reaction with surface silanol groups or crosslinkers.

Low Viscosity: Excellent wetting and penetration properties for treating porous substrates.

Stability Enhancement:Effectively neutralizes active sites on fillers to prevent "structured-up" hardening during storage.

Efficient Dispersion: Low viscosity allows for excellent wetting and uniform coating of fine powders.

Applications:

Filler & Powder Treatment: Used as a processing aid in silicone rubber compounding to prevent "structure-up" (creping) of silica-filled stocks, and for surface treatment of fumed silica and inorganic fillers.

Polymer ModificationIntermediate: Serves as a reactive intermediate for synthesizing silicone-modified resins (e.g., silicone-polyester, silicone-epoxy, silicone-acrylic) to enhance weatherability and durability.

Surface Hydrophobization:Provides water repellency through surface treatment of glass fibers, pigments, granular materials, and inorganic fillers.

Reactive Diluent: Used to adjust the viscosity of high-molecular-weight silicone systems without compromising reactivity.

Anti-stick Agent: Used as a component in paper release coatings and textile finishing agents.
