Industrial Applications of POLY(DIETHOXYSILOXANE)
| Industry | Application | Process |
|---|---|---|
| Electronics Industry | Used as a precursor for semiconductor device encapsulation materials to enhance thermal resistance and dielectric performance | Sol-gel process: co-hydrolysis and condensation with tetraethyl orthosilicate to form a SiO₂-based network structure |
| Coatings Industry | Acts as a crosslinker in organic-inorganic hybrid coatings to improve coating hardness, abrasion resistance, and adhesion | In acrylic or epoxy resin systems, undergoes acid-catalyzed hydrolysis followed by condensation with polymer hydroxyl groups |
| Ceramics Industry | Applied as a low-temperature sintering aid and green-body reinforcement agent to improve densification behavior | Mixed with ceramic powders such as alumina or zirconia; forms a SiO₂ bonding phase via hydrolysis, drying, and thermal treatment |
| Optics Industry | Used to produce anti-reflective coatings, high-refractive-index films, and other optical thin-film materials | Film deposition via spin-coating or dip-coating, followed by hydrolysis-condensation and thermal treatment to yield amorphous SiO₂ films |
| Catalyst Support | Serves as a precursor for silica supports, enabling preparation of high-surface-area SiO₂ supports with controlled pore size | Sol-gel process with controlled hydrolysis/condensation conditions; subsequent drying (e.g., supercritical drying) yields aerogel or xerogel supports |
Manufacturing Quality Control of POLY(DIETHOXYSILOXANE)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Purity (main component) | GC-FID | Quantitative determination based on retention time and peak area comparison with certified reference standard. |
| Water content | Karl Fischer titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Ethanol content | GC-FID | Separation and quantification of ethanol using capillary column and flame ionization detection. |
| Acidity (as HCl) | Acid-base titration | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on evaporation | Gravimetric analysis | Evaporation of sample under controlled conditions followed by weighing of non-volatile residue. |
| Density at 20 C | Digital densitometer | Measurement of mass per unit volume using oscillating U-tube principle. |
| Refractive index at 20 C | Refractometry | Determination of light bending angle through sample at specified temperature to infer composition. |
| Iron (Fe) content | ICP-OES | Atomization and excitation of elements in argon plasma; quantification via characteristic emission wavelengths. |
| Aluminum (Al) content | ICP-OES | Same principle as Fe analysis, using element-specific emission lines for quantitative determination. |
| Chloride (Cl-) content | Ion chromatography | Separation of anions on ion-exchange column followed by conductivity detection. |
| Viscosity at 25 C | Rotational viscometry | Measurement of torque required to rotate a spindle in the sample at controlled shear rate and temperature. |
| pH of aqueous solution (10% w/w) | pH meter | Electrochemical measurement of hydrogen ion activity in diluted aqueous sample using calibrated glass electrode. |
