Description

Silane, Isocyanato- CAS NO 13730-13-7 is a highly reactive organosilicon compound featuring both an isocyanate group and hydrolysable silane functionality. This dual reactivity makes it a critical coupling agent and surface modifier for creating durable bonds between organic polymers and inorganic substrates. It is primarily used by manufacturers in the adhesives, sealants, coatings, and composite materials industries seeking to enhance product performance and longevity.

Application

• Adhesive & Sealant Formulation: Acts as a key adhesion promoter, significantly improving bond strength and moisture resistance in polyurethane and silicone-based systems.
• Surface Pretreatment for Coatings: Used to functionalize glass, metal, and mineral surfaces, ensuring excellent coating adhesion and corrosion protection.
• Polymer Modification & Composite Manufacturing: Serves as a crosslinking agent and compatibilizer in filled polymers and fiber-reinforced plastics (FRP) to enhance mechanical properties.
• Silane-Terminated Polymers (STP): A fundamental building block for manufacturing moisture-curable MS polymers and hybrid sealants with superior weatherability.
• Immobilization of Biomolecules: Utilized in biotechnology and diagnostics to create functionalized surfaces for attaching proteins, enzymes, or DNA probes.
• Specialty Chemical Synthesis: An important intermediate for synthesizing more complex silane derivatives with tailored properties for advanced material science.

Quality Control

Our production of Isocyanatopropyltriethoxysilane adheres to stringent quality management protocols. Every batch undergoes comprehensive analysis, including assay by GC or titration and impurity profiling, to ensure high purity and consistent performance. Certificates of Analysis (COA) documenting all key parameters are provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize hydrolysis and polymerization. Due to its moisture-sensitive and highly volatile nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong acids/bases.
