Industrial Applications of 67990-05-0
| Industry | Application | Process |
|---|---|---|
| Coatings | Red colorant for automotive OEM coatings, refinish coatings, and industrial protective coatings | Wet-milled and dispersed in acrylic, polyester, or epoxy resin systems |
| Plastics | Colorant for polyolefins (PP, PE), PVC, PS, and engineering plastics (ABS, PC) | Melt-compounded via extrusion; requires excellent thermal stability (heat resistance ≥ 280 °C) |
| Inks | Colorant for high-end packaging printing inks (e.g., flexographic and gravure inks) and metallic decorative inks | Formulated with chlorinated polypropylene, nitrocellulose, or polyamide resins and processed into color dispersions via high-speed dispersion |
| Cosmetics | Colorant approved by the EU and China for use in lipsticks, eyeshadows, and other color cosmetics (subject to concentration limits) | After micronization, uniformly blended with bases such as lanolin and petrolatum to comply with the Cosmetics Safety Technical Specifications |
Manufacturing Quality Control of 67990-05-0
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Purity (main component) | HPLC-UV | Quantifies pigment content by separation on a reversed-phase column and UV absorbance detection at characteristic wavelength. |
| Color Strength | Reflectance Spectrophotometry | Compares reflectance curve of sample vs. reference standard to calculate relative tinting strength. |
| Particle Size Distribution | Laser Diffraction | Measures scattering pattern of dispersed particles in liquid medium to derive size distribution. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration using iodine reagent to quantify water based on stoichiometric reaction. |
| Ash Content | Gravimetric Analysis (Ignition at 550 C) | Determines inorganic residue after high-temperature combustion and weighing of residual ash. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Simultaneously quantifies multiple metals after acid digestion by measuring element-specific atomic emission intensities. |
| Chloride Content | Potentiometric Titration with AgNO3 | Measures chloride ions via silver nitrate titration monitored by silver ion-selective electrode. |
| pH of Aqueous Extract | pH Meter Measurement | Determines acidity/alkalinity of water extract prepared under standardized conditions. |
| Organic Volatile Impurities | GC-MS | Identifies and quantifies residual solvents or volatile organics using gas chromatographic separation and mass spectral detection. |
| Bulk Density | ASTM D1895 Method A (Tapped Density) | Measures mass per unit volume after controlled tapping of a graduated cylinder containing the powder. |
| Heat Stability | Thermogravimetric Analysis (TGA) | Evaluates weight loss profile under controlled heating to assess decomposition onset temperature. |
| Lightfastness | Xenon Arc Weatherometer (ISO 105-B02) | Exposes samples to accelerated xenon lamp irradiation and evaluates color change using gray scale or Delta E. |
