Product Overview
Ethyltrimethoxysilane is a high-purity (97%) organofunctional silane designed for surface modification, adhesion promotion, and moisture-resistant coatings. This trialkoxysilane undergoes hydrolysis in the presence of water, forming silanol groups that bond covalently with inorganic substrates like glass, metals, and silica. The ethyl functional group enhances compatibility with organic polymers, making it ideal for improving adhesion in composite materials, coatings, and sealants. Its low viscosity and high reactivity ensure efficient application in solvent-based or aqueous systems. The AcroSeal® packaging preserves purity by minimizing moisture exposure, extending shelf life, and preventing premature hydrolysis. This silane is particularly effective in enhancing the durability of paints, adhesives, and fiber-reinforced composites by creating a molecular bridge between organic and inorganic interfaces. Its versatility extends to use as a cross-linking agent in silicone-based formulations, where it improves mechanical strength and thermal stability.
FAQs
1. How does Ethyltrimethoxysilane improve adhesion in coatings?
It forms a chemical bond between the substrate and the organic coating, reducing delamination and enhancing durability by creating a hybrid organic-inorganic interface.
2. Is this silane compatible with water-based formulations?
While it hydrolyzes in water, pre-hydrolyzed solutions or emulsifiers are often required for stable integration into water-based systems.
3. What alternatives exist for non-glass substrates?
For metals or plastics, amino- or epoxy-functional silanes may offer better compatibility depending on the polymer matrix.
4. How should unopened bottles be stored to prevent degradation?
Store in a cool, dry place with the original AcroSeal® cap tightly closed to exclude moisture and air.
5. Does this product contain stabilizers or additives?
No, this is a 97% pure grade without added stabilizers, ensuring consistent reactivity in formulations.
