Description

Poly[Oxy(Methyl-1,2-Ethanediyl)],A-[[[3-(Trimethoxysilyl)Propyl]Amino]Carbonyl]-W-[[[[3-(Trimethoxysilyl)Propyl]Amino]Carbonyl]Oxy]- CAS NO 216597-12-5 is a specialized, dual-functional silane-terminated polyether compound. This product is engineered to act as a high-performance coupling agent and adhesion promoter, creating robust bonds between organic polymers and inorganic substrates. It is essential for formulators and manufacturers in the adhesives, sealants, coatings, and composite materials industries seeking to enhance durability, moisture resistance, and mechanical properties.

Application

• Adhesives & Sealants: As a key adhesion promoter in moisture-curing polyurethane (PU) and silane-modified polymer (SMP) systems for construction, automotive, and industrial assembly.
• Coatings & Paints: To improve the adhesion of protective and decorative coatings to challenging substrates like glass, metals, and treated plastics.
• Composite Materials: As a coupling agent in fiberglass, mineral-filled plastics, and rubber compounds to enhance filler-matrix interaction and composite strength.
• Surface Modification: For the chemical treatment of nanoparticles, silica, and other inorganic materials to improve their compatibility and dispersion in organic polymer matrices.
• Elastomers & Resins: Incorporated to modify the crosslinking density and network structure, leading to improved elasticity, tear strength, and environmental resistance.

Quality Control

Our production of this silane-terminated polyether adheres to strict quality management protocols. Every batch is characterized using advanced analytical techniques to ensure consistency in functionality, molecular weight distribution, and silane content. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and key physical properties is provided with each shipment to guarantee it meets your specific formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive). Store in a cool, dry place at room temperature (15-25°C/59-77°F) under a dry, inert atmosphere (e.g., nitrogen) to prevent premature hydrolysis and maintain optimal shelf life. Keep away from sources of heat and moisture.
