Description

Tetrakis(2-Octyldodecyloxy)Silane, Tech-95 is a high-purity organosilicon compound characterized by its four long-chain alkyloxy substituents. This structure is critical for its role as a versatile coupling agent and surface modifier, enhancing compatibility and adhesion between organic polymers and inorganic substrates. It is essential for manufacturers in the plastics, coatings, and advanced materials sectors seeking to improve product performance and durability.

Application

• Polymer Additive & Coupling Agent: Enhances the dispersion of fillers (e.g., silica, clay) in polyolefins, elastomers, and engineering plastics, improving mechanical properties and processability.
• Surface Modification for Nanoparticles: Used to functionalize the surface of metal oxides and other inorganic nanoparticles to prevent agglomeration and promote compatibility in composite materials.
• Adhesion Promoter in Coatings & Inks: Improves the adhesion of paints, inks, and adhesives to difficult-to-bond substrates like metals, glass, and treated plastics.
• Hydrophobic Agent: Imparts water-repellent properties to surfaces in construction materials, textiles, and protective coatings.
• Lubricant & Release Agent Intermediate: Serves as a key raw material in formulating high-performance lubricants and mold release agents.
• Electronic Materials: Used in the passivation and encapsulation layers for electronic components to enhance moisture resistance and reliability.
