In the vast landscape of specialty chemicals, organosilanes stand out for their unique reactivity and versatility. Triethoxy(2,4,4-trimethylpentyl)silane, identified by CAS number 35435-21-3, is a prime example, offering significant benefits in both construction materials protection and polymer science. As a dedicated manufacturer and supplier, we provide this high-purity chemical to meet the diverse needs of industries worldwide. If you're looking to buy this compound, understanding its properties is key.

Chemical Profile of Triethoxy(2,4,4-trimethylpentyl)silane

This silane is characterized by its chemical formula C14H32O3Si and a molecular weight of approximately 276.49 g/mol. Typically appearing as a colorless to light yellow transparent liquid with a faint odor, it boasts a density around 0.878 g/cm³ at 25°C and a boiling point of approximately 215.8°C at 760 mmHg. Its flash point, around 95.9°C, classifies it as a combustible liquid, requiring appropriate handling. The refractive index is approximately 1.426.

The key functional groups are the three ethoxy (-OCH2CH3) groups attached to the silicon atom and the branched 2,4,4-trimethylpentyl alkyl chain. The ethoxy groups are susceptible to hydrolysis, forming reactive silanol groups (-Si-OH) in the presence of moisture. These silanol groups are the active sites for bonding with inorganic substrates or self-condensation to form siloxane polymers.

Applications: Where Performance Matters

The dual nature of Triethoxy(2,4,4-trimethylpentyl)silane allows it to excel in several critical applications:

  • Water Repellency for Construction: This is perhaps its most significant application. When formulated and applied to concrete, masonry, stone, and other porous building materials, it penetrates deeply and reacts to form a hydrophobic surface. This treatment dramatically reduces water absorption, protecting structures from freeze-thaw cycles, chemical attack, and the damaging effects of moisture. Treated surfaces retain their natural appearance and breathability. If you need to buy for construction projects, we are your reliable supplier.
  • Filler and Pigment Modification: In the polymer industry, it serves as a silane coupling agent. It modifies the surface of inorganic fillers and pigments, making them more compatible with organic polymer matrices, particularly polyolefins. This improved compatibility leads to better dispersion of the fillers, reduced agglomeration, and enhanced mechanical properties of the composite material, such as improved tensile strength and impact resistance.
