English description（英文原文，共 1404 字符）
Product Name:p-Bis(trimethoxysilylmethyl)benzene
English Name:p-Bis(trimethoxysilylmethyl)benzene
CAS No.:193358-40-6
Aliases:1,4-Bis(trimethoxysilylmethyl)benzene, p-Bis(trimethoxysilylmethyl)benzene
Molecular Formula:C14H26O6Si2
Physical Properties:Colorless to light yellow transparent liquid, soluble in alcohols, esters and other organic solvents; slowly hydrolyzes upon contact with water, releasing methanol. Featuring two trimethoxysilyl functional groups, it exhibits high reactivity and can form stable siloxane bonds with inorganic surfaces via hydrolytic condensation. High boiling point, moderate flash point, should be stored sealed, protected from light, and kept dry.
Uses:Used as a crosslinking agent and coupling agent for silicone-modified epoxy resins, polyurethanes and other polymers, significantly improving adhesion strength and water resistance to inorganic substrates such as glass and metals. Widely applied in electronic packaging materials, coatings, and adhesives, as well as for preparing organic-inorganic hybrid materials and functional silane-modified surfaces.
Technical Specifications:
Appearance: colorless to light yellow transparent liquid
Purity: ≥98%
Molecular weight: 346.52
Density: approx. 1.05 g/cm³ (25°C)
Reactivity: bis(trimethoxysilyl) groups with electrophilic benzylic positions, capable of hydrolytic condensation and α-alkylation reactions
