Description

2-Butyl-Triethoxysilane is a specialized organosilicon compound used as a key coupling agent and surface modifier. Its value lies in its ability to form durable bonds between inorganic substrates and organic polymers, enhancing material performance. This product is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced composite materials and surface treatment applications.

Application

• Coupling agent for mineral-filled composites (e.g., silica, clay) to improve mechanical properties and dispersion.
• Surface pretreatment for glass, metals, and minerals to enhance adhesion of paints, inks, and adhesives.
• Hydrophobic modifier in construction materials like concrete and masonry for water repellency.
• Crosslinking agent or chain extender in silicone polymer synthesis and modification.
• Intermediate in the production of more complex silane derivatives for specialized applications.
• Adhesion promoter in tire and rubber manufacturing to improve filler-rubber interaction.
• Component in sol-gel processes for creating hybrid organic-inorganic coatings and films.

Quality Control

Our 2-Butyl-Triethoxysilane is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and key physical properties are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent contact with atmospheric moisture, which can lead to hydrolysis and degradation.
