Tris[(2-butylene)iminooxy]methylsilane: An Overview of Properties and Applications
Tris[(2-butylene)iminooxy]methylsilane, also known as DOWSIL Z-9075, Honeywell OS1000, and other trade names, is a versatile organosilicon compound that finds applications in various industries. This article provides an overview of the properties and applications of Tris[(2-butylene)iminooxy]methylsilane, with a focus on its use as a crosslinking agent, adhesion promoter, and surface modifier.
Chemical Properties
Tris[(2-butylene)iminooxy]methylsilane has the chemical formula C13H33N3O3Si and a molecular weight of 307.52 g/mol. It is a clear, colorless to yellowish liquid with a boiling point of 285-290°C, a flashpoint of 104°C, and a density of 1.02 g/cm3 at 25°C. The compound is soluble in common organic solvents such as ethanol, acetone, and toluene, and reacts readily with water and acidic or basic solutions.
Tris[(2-butylene)iminooxy]methylsilane contains three functional groups: a trialkoxysilyl group (-Si(OR)3) that can hydrolyze to form a silanol (-Si-OH) and attach to surfaces, and two oxime groups (-C=N-OH) that can undergo condensation reactions to form a crosslinking network. The butylene groups (-C4H8-) provide flexibility and steric hindrance to the molecule, which influences its reactivity and compatibility with different substrates.
Applications
Tris[(2-butylene)iminooxy]methylsilane has several applications in the fields of coatings, adhesives, sealants, and composites. Its key functions are to enhance the adhesion between dissimilar materials, improve the durability and chemical resistance of coatings, and modify the surface properties of substrates.
As a crosslinking agent, Tris[(2-butylene)iminooxy]methylsilane can react with polyfunctional compounds such as polyesters, polyurethanes, and epoxies to form three-dimensional networks that improve the mechanical and thermal properties of the materials. The oxime groups in the silane molecule can undergo condensation reactions with the hydroxyl or carboxyl groups in the polymer matrix, leading to the formation of covalent bonds that link the chains together. This crosslinking process improves the hardness, toughness, and solvent resistance of the cured materials, making them suitable for applications such as coatings for metal, wood, and plastics, adhesives for automotive and aerospace industries, and sealants for buildings and electronics.
As an adhesion promoter, Tris[(2-butylene)iminooxy]methylsilane can enhance the bonding between substrates that have different surface energies or chemistries. The trialkoxysilyl group in the molecule can react with the hydroxyl groups on the surface of glass, ceramics, metals, and polymers, forming a strong chemical bond that resists peeling, cracking, and corrosion. The butylene groups in the molecule can also provide a cushioning effect that reduces stress and strain at the interface, improving the long-term durability of the bond. This adhesion promotion mechanism is useful for applications such as coatings for automotive, aerospace, and marine industries, adhesives for electronics and medical devices, and sealants for construction and industrial applications.
As a surface modifier, Tris[(2-butylene)iminooxy]methylsilane can alter the wettability, lubricity, and anti-fouling properties of substrates. The trialkoxysilyl group in the molecule can form a monolayer on the surface of substrates, reducing the surface tension and increasing the contact angle of liquids such as water, oil, and ink. This hydrophobic or oleophobic effect can be useful for preventing stains, dirt, and biofilms from adhering to the surface, improving the cleanliness and longevity of the substrate. The butylene groups in the molecule can also impart a low-friction or anti-wear effect to the surface, reducing the wear and tear caused by sliding or rolling contacts. This surface modification mechanism is applicable for applications such as coatings for textiles, paper, and plastics, lubricants for machinery and transportation, and anti-fouling agents for marine and biomedical devices.
Conclusion
Tris[(2-butylene)iminooxy]methylsilane is a multifunctional organosilicon compound that has a wide range of applications in the coatings, adhesives, sealants, and composites industries. Its unique combination of crosslinking, adhesion promotion, and surface modification properties make it a valuable ingredient in many formulations that require improved performance and durability.
