Description

4-[2-(Triethoxysilyl)Vinyl]Benzocyclobutene is a highly specialized organosilicon compound that serves as a critical coupling agent and monomer in advanced material synthesis. Its unique bifunctional structure, combining a reactive benzocyclobutene moiety with a hydrolyzable triethoxysilyl group, enables it to form robust covalent bonds between organic polymers and inorganic substrates. This product is essential for researchers and manufacturers in the electronics, aerospace, and high-performance composites industries seeking to enhance material adhesion, thermal stability, and dielectric properties.

Application

• As a key adhesion promoter in microelectronics packaging, underfills, and die-attach materials.
• As a crosslinking agent and surface modifier for silica, glass, and metal oxides in composite materials.
• In the synthesis of high-temperature resistant polymers and polybenzocyclobutene (PBCB)-based resins for aerospace applications.
• For the surface functionalization of nanoparticles to improve dispersion in polymer matrices.
• As a reactive monomer in the production of low-dielectric-constant (low-k) materials for semiconductor interconnects.
• In the development of specialty coatings and sealants requiring exceptional chemical and thermal endurance.

Quality Control

Every batch of 4-[2-(Triethoxysilyl)Vinyl]Benzocyclobutene is manufactured and tested under a strict quality management system. We ensure high purity and batch-to-batch consistency through advanced analytical techniques including GC, HPLC, and NMR. A comprehensive Certificate of Analysis (COA), detailing identity, purity, and impurity profiles, is provided with each shipment to support your quality assurance and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 2-8°C or as specified on the label. This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
