Description

Triethoxy(2,4,4-Trimethylpentyl)Silane is a versatile organosilicon compound, specifically a branched alkyltriethoxysilane, that serves as a crucial coupling agent and surface modifier. Its primary value lies in its ability to form strong, durable bonds between inorganic substrates and organic polymers, enhancing composite material performance. This silane is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producers of mineral-filled plastics and advanced composites who require improved mechanical properties and environmental resistance.

Application

• Adhesion Promoter: Used in primers and coatings to improve the adhesion of paints, inks, and adhesives to metallic (especially aluminum) and mineral surfaces.
• Filler Treatment: Acts as a coupling agent for mineral fillers (e.g., silica, clay, talc) in rubber and plastic composites, enhancing dispersion and mechanical strength.
• Water Repellency: Imparts hydrophobic properties to construction materials like concrete, masonry, and stone for protective treatments.
• Crosslinking Agent: Functions as a crosslinker in moisture-curing silicone sealants and RTV (Room Temperature Vulcanizing) elastomers.
• Surface Modification: Modifies the surface energy of pigments and nanoparticles to improve compatibility and stability in various formulations.
• Fiber Sizing: Used as a component in sizing formulations for glass and other reinforcing fibers to improve resin matrix bonding.

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). Keep the container tightly sealed when not in use to prevent contact with atmospheric moisture, which can lead to hydrolysis and reduced efficacy.
