In the fields of coatings, adhesives, and composite materials, performance bottlenecks often directly impact the quality and lifespan of the final product. Challenges such as insufficient adhesion, poor weather resistance, and inadequate mechanical strength have long been core concerns within the industry. Vinyltriisopropoxysilane Crosile-173, an efficient silane coupling agent, is precisely designed as a key additive to solve these problems.

Why Choose Vinyltriisopropoxysilane Crosile-173?

Vinyltriisopropoxysilane Crosile-173(VTMO) is a colorless or light yellow transparent liquid with a purity of ≥98.0%, a density of 0.860–0.867 g/mL, a boiling point of 180°C, and a refractive index of 1.43. CAS No.:18023-33-1)

The unique chemical structure of Crosile-173 enables it to form stable "molecular bridges" between inorganic materials (such as glass, metals) and organic polymers (such as acrylic resins, polyurethanes). This bridging effect not only significantly enhances the adhesion between the coating and the substrate but also improves the overall cohesive strength of the material through its excellent cross-linking capability.

Vinyltriisopropoxysilane Core Performance Advantages:

1. Superior Adhesion
   Crosile-173 can form strong chemical bonds with hydroxyl groups on the substrate surface, fundamentally solving the problems of coating delamination and inadequate adhesion. Whether on metal, plastic, or glass substrates, Crosile-173 delivers exceptional dry and wet adhesion.

2. Exceptional Durability
   Coatings incorporating Crosile-173 exhibit excellent resistance to water, chemical corrosion, and UV aging. Even under harsh environmental conditions, the coating maintains long-term performance stability, significantly extending the service life of the product.

3. Excellent Cross-Linking Capability
   Crosile-173 effectively increases the cohesive strength and hardness of the film, giving the product superior wear and scratch resistance. Furthermore, it demonstrates very good stability in water-based systems, ensuring the formulation remains stable during storage.

Vinyltriisopropoxysilane Main Application Areas:

• Industrial Coatings: Used in anti-corrosive coatings for metal and plastic substrates, providing long-lasting protection.

• Architectural Coatings: Enhances weather resistance and anti-fouling properties in silicone-acrylic exterior wall coatings.

• Composite Materials: Modifies polyurethane-acrylate emulsions to balance mechanical strength and water resistance.

• Wires & Plastics: Acts as a cross-linking agent to improve the heat resistance and electrical properties of polyethylene.

Technical Highlights:

A key distinguishing feature of Crosile-173 is its relatively slow hydrolysis of the isopropoxy groups. This grants it better storage stability in water-based systems while ensuring sufficient compatibility and reaction efficiency with the material matrix.
