Industrial Applications of 18765-38-3
| Industry | Applications | Process |
|---|---|---|
| Coatings & Inks | Low-temperature curing coatings, heat-resistant coatings, corrosion-resistant coatings | Used as a silane coupling agent or crosslinker; forms siloxane networks via hydrolysis-condensation reactions to enhance coating adhesion, weather resistance, and thermal stability. |
| Foundry Industry | Precision investment casting shell molds | Serves as a modifier or replacement for ethyl silicate binders in shell mold manufacturing, enabling control of gelation time and shell strength. |
| Electronic Materials | Electronic encapsulation materials, insulating coatings | Utilized in sol-gel processing to prepare sols and gels for surface insulation and moisture protection of electronic components. |
| Inorganic Materials Processing | Ceramic precursors, refractory materials | Applied in sol-gel processing to generate high-purity silica or silicon oxide networks via low-temperature hydrolysis-condensation reactions. |
| Surface Treatment | Metal surface treatment, glass surface modification | Employed for pre-treatment of metal or glass substrates to form silane-based surface films, improving corrosion resistance or serving as a primer layer for subsequent coatings. |
| Chemical Synthesis | Synthesis of organosilicon compounds | Serves as a raw material; the reactivity of butoxyethoxy functional groups enables grafting or modification reactions. |
Manufacturing Quality Control of 18765-38-3
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area against calibrated standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, and sulfur dioxide in pyridine/methanol medium. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color to APHA platinum-cobalt standard scale using transmitted light at 455 nm. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle based on frequency shift. |
| Refractive Index at 20 C | Refractometry | Measures bending of light passing through sample to determine refractive index at specified temperature. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known mass of sample under controlled conditions and weighs non-volatile residue. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals (as Pb) | ICP-OES | Atomizes and excites sample in plasma; measures characteristic emission wavelengths for metal elements. |
| Iron Content | ICP-OES | Same principle as heavy metals, optimized for Fe spectral line detection at 238.204 nm. |
| Aldehyde Impurities | GC-MS | Separates volatile impurities by GC and identifies/quantifies aldehydes via mass spectral fragmentation patterns. |
| Viscosity at 25 C | Rotational Viscometry | Measures resistance to flow using rotating spindle immersed in sample at controlled temperature. |
