Character and Benefits:

1.High-Functionality Reactive Site:
Features a unique mono-capped structure with dual hydroxyethoxypropyl groups concentrated at one terminus. This design provides a high-density, reactive anchor point for more efficient and stable covalent incorporation into polymer matrices compared to conventional mono-functional analogs.
2.Permanent Surface Modification:
Reacts chemically with isocyanates, acids, or other co-monomers to form stable silicone-organic block or graft copolymers. This ensures permanent modification, preventing migration and leaching, and delivering long-lasting performance.
3.Exceptional Surface Enrichment & Performance:
The asymmetric structure (silicone chain vs. reactive organic head) promotes spontaneous migration and enrichment at the polymer-air interface. This delivers:
Superior, Durable Soft Hand-Feel & Silky Lubricity.
Enhanced Abrasion, Scratch, and Mar Resistance.
Excellent and Persistent Water & Stain Repellency (Hydro/Oleophobicity).
4.Improved Processing & Compatibility:
Acts as an efficient internal processing aid, improving flow, mold release, and demolding. The dual organic groups enhance compatibility with polar resins (e.g., polyurethane, polyester), facilitating easier blending and more homogeneous modification.
5.Synergistic Effect for Toughness & Flexibility:

Contributes to improved low-temperature flexibility and impact resistance in the final polymer by introducing flexible silicone segments at strategic points within the network.

Usage:
This high-functionality modifier is primarily designed for applications demanding permanent, high-performance surface properties and internal lubrication through chemical bonding.
1.High-End Coatings (Primary Use):
Anti-Graffiti & Easy-Clean Coatings: A key additive for solvent-based polyurethane (PU) or acrylic systems. It provides a synergistic combination of exceptional, durable anti-adhesion properties against paints and markers, outstanding stain resistance, and a superior soft-touch finish. The bonded silicone layer ensures graffiti and stains can be removed more easily without damaging the coating.
Soft-Feel Coatings: Imparts a rich, dry, and durable silky feel to automotive interiors, consumer electronics, tool grips, and premium packaging coatings.
2.Reactive Polymer Modifier:
Used in the synthesis of specialty silicone-modified polyurethanes (SPU) or polyesters. Ideal for producing elastomers, resins, or fibers that require permanent slip, water repellency, and flexibility from within the polymer backbone.
3.Performance Additives for Engineering Plastics & Elastomers:
Incorporated into TPU, PVC, Nylon, or other polar engineering polymers via compounding or reactive processing to permanently reduce friction, improve abrasion resistance, and enhance water repellency.
4.Specialty Release Agents & Lubricants:
Can be formulated as a reactive component in internal or external release systems for polyurethane molding (e.g., foams, elastomers), providing multiple release cycles and improving surface finish.

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

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