Industrial Applications of 2182-66-3
| Industry | Application | Process |
|---|---|---|
| Organosilicon Materials | Crosslinker for silicone rubber | Used as a crosslinker in room-temperature vulcanizing (RTV) silicone rubber, reacting with silanol groups to form Si–O–Si bonds and enabling vulcanization |
| Coatings & Inks | Adhesion promoter | Incorporated into coating formulations to improve adhesion of organic coatings to inorganic substrates such as glass and metal |
| Adhesives | Coupling agent | Employed to modify acrylic and epoxy adhesive systems, enhancing interfacial bonding strength with inorganic fillers (e.g., silica, calcium carbonate) |
| Plastics Processing | Surface treatment agent | Applied to pre-treat inorganic fillers (e.g., talc, mica) to improve their dispersion and compatibility in non-polar resins such as polypropylene and polyethylene |
| Electronic Encapsulation | Sealant component | Serves as a key crosslinking component in one-component acetoxy-cure RTV silicone sealants, delivering low modulus, high elasticity, and excellent electrical insulation |
Manufacturing Quality Control of 2182-66-3
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantitative separation and detection of DMDES and impurities using a capillary column and flame ionization detector. |
| Acetic Acid Content | Acid-Base Titration | Neutralization of liberated acetic acid with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Moisture Content | Karl Fischer Titration | Electrochemical determination of water based on the stoichiometric reaction of iodine with sulfur dioxide in the presence of water. |
| Color | Visual Comparison or Spectrophotometry (APHA) | Comparison of sample color against platinum-cobalt standard solutions or measurement of absorbance at 455 nm. |
| Density | Digital Density Meter | Measurement of mass per unit volume at controlled temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determination of light bending angle at air-sample interface using calibrated refractometer at specified temperature. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of known sample mass to dryness followed by weighing of non-volatile residue. |
| Chloride Content | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Atomization of sample and measurement of absorption of characteristic wavelength radiation by ground-state metal atoms. |
| Iron Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomization and excitation of elements in high-temperature plasma, followed by detection of element-specific emission lines. |
| pH of Aqueous Solution | pH Meter Measurement | Electrochemical measurement of hydrogen ion activity in a 1% aqueous solution using calibrated glass electrode. |
| Volatile Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by GC followed by identification and quantification of volatile impurities via mass spectral fragmentation patterns. |
