Description

Silane, (2,2-Dimethylpropoxy)dimethyl(1-methylethyl)- is a specialized organosilicon compound designed for advanced surface modification and coupling applications. Its unique branched alkoxy and isopropyl substituents provide controlled reactivity and enhanced compatibility with various polymer matrices. This silane is essential for formulators and material scientists seeking to improve adhesion, dispersion, and performance in composite systems. The product is identified by CAS No. 959016-78-5.

Application

• Adhesion Promoter: Enhances the bond between inorganic fillers (e.g., silica, glass) and organic polymer resins in composites and sealants.
• Surface Modification Agent: Used to functionalize nanoparticles, pigments, and mineral surfaces to improve dispersion and stability in coatings and plastics.
• Crosslinking Agent: Employed in silicone rubber and resin formulations to facilitate moisture-cure crosslinking for elastomers and adhesives.
• Coupling Agent for Mineral-Filled Composites: Critical in manufacturing high-performance filled polyolefins, engineering plastics, and thermoplastic elastomers (TPEs).
• Water Repellency Treatments: Imparts hydrophobic properties to construction materials, textiles, and stone.
• Primer Formulations: Serves as a key ingredient in primers for metals, glass, and plastics to promote coating adhesion and corrosion resistance.
