Description

Silane, [1,4-Cyclohexanediylbis(Oxy)]Bis[Trimethyl-, trans- is a specialized organosilicon compound featuring a trans-cyclohexane bridge linking two trimethoxysilane groups. This unique structure makes it a highly effective coupling agent and surface modifier, providing superior adhesion and compatibility between inorganic materials and organic polymers. It is essential for manufacturers in the advanced composites, coatings, and electronics industries seeking to enhance material performance and durability.

Application

• As a coupling agent in fiberglass-reinforced plastics and advanced composite materials to improve mechanical strength and moisture resistance.
• As a surface treatment agent for glass, minerals, and metal oxides to promote adhesion in coatings, inks, and adhesives.
• As a key crosslinking agent and modifier in silicone resin and rubber formulations to tailor thermal and chemical stability.
• In the formulation of specialty coatings and sealants to enhance weatherability, corrosion protection, and bonding to difficult substrates.
• As an adhesion promoter in electronic encapsulants and underfill materials for improved reliability.
• For the functionalization of fillers (e.g., silica, clay) to improve dispersion and interfacial properties in polymer matrices.

Quality Control

Our production of trans-1,4-Bis(trimethoxysilyl)cyclohexane adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including GC and NMR, to ensure high purity and consistent isomeric composition. Certificates of Analysis (COA) detailing all specifications are provided to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be kept under a dry inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis and maintain efficacy. Keep away from strong bases and incompatible organic solvents.
