Purity:≥97%

Viscosity (25°C):30-100cp

Molecular weight:1000,2000

Character and Benefits:

1. Unique Asymmetric Structure:

This reactive mono-capped silicone oil features a unique hybrid architecture with a silicone chain at one end and a reactive hydroxyethoxypropyl group at the other. This enables its covalent incorporation into polymer backbones (e.g., polyurethane, polyester) to create stable silicone-organic block copolymers.

2. Superior Surface Performance:

It combines the exceptional soft hand-feel and inherent surface activity of silicone with the permanent anti-graffiti properties offered by the organic segment. This synergy delivers superior hand-feel and more durable anti-graffiti performance compared to conventional symmetric (bis-capped) analogs.

3. Enhanced Polymer Processing & Properties:

Improves processing fluidity and mold release.

Imparts excellent abrasion, scratch, and mar resistance.

Provides lasting water repellency (hydrophobicity) and stain resistance.

Improves low-temperature flexibility and reduces polymer stiffness.

4. Permanent Modification:

As a reactive modifier, it offers permanent effects through covalent bonding, minimizing migration and ensuring long-term performance stability.

Usage:

This mono-capped hydroxyethoxypropyl silicone oil is primarily designed as a reactive modifier and additive for high-performance coatings and polymers, including silicone rubber, polyurethane (PU), polyester, and various coating systems.

1. High-Performance Anti-Graffiti & Easy-Clean Coatings:

It is an ideal additive for solvent-based polyurethane anti-graffiti coatings. It provides:

Excellent and durable anti-graffiti and mark resistance.

Enhanced hydro- and oleophobic properties for superior stain resistance.

A supplementary release effect, facilitating the removal of graffiti and contaminants.

2. Reactive Polymer Modifier:

Used in the synthesis of silicone-polyurethane or silicone-polyester block copolymers for textiles, elastomers, or coatings, where it permanently imparts softness, flexibility, and surface slip.

3. Functional Additive/Release Agent:
Can serve as an effective internal or external release agent and lubricant in various polymer processing applications, improving demolding and surface quality.

Potential Additional Applications to Consider:

Textile & Fiber Treatment: As a softener and water repellent for synthetic fibers or fabrics, providing a durable, soft hand-feel.

Ink & Printing Additive: To improve slip, abrasion resistance, and water repellency in specialty inks or overprint varnishes.

Adhesive & Sealant Modifier: To enhance flexibility, reduce surface tack, and improve water resistance in adhesives or sealants.

Recommended dosage: 0.5％～5％ of the total formula.

Package:25kg/drum.Sealed storage for 12 months in normal temperature.
