Industrial Applications of Pigment Yellow 138
| Industry | Application | Process |
|---|---|---|
| Coatings | Yellow colorant for automotive OEM coatings, refinish coatings, and industrial coatings | Wet-milled and dispersed in acrylic, polyester, or alkyd resin systems |
| Plastics | Coloration of thermoplastic resins including polyolefins (PP, PE), PVC, PS, and ABS | Compounded with resin and processed via extrusion, injection molding, or blow molding; heat resistance up to 280–300°C |
| Inks | Yellow pigment for packaging printing inks (e.g., gravure, flexographic) and publication inks | Compatible with vinyl chloride–vinyl acetate copolymer, polyamide, or nitrocellulose binders; prepared by high-speed dispersion or bead milling |
| Synthetic Fibers | Direct dope dyeing of polyester (PET) and polyamide (nylon 6/66) spin melts | Pre-blended with chips prior to melt spinning; in-situ high-temperature coloring process at 270–290°C |
Manufacturing Quality Control of Pigment Yellow 138
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Purity (main component) | HPLC-UV | Quantifies PY138 content by separation on reversed-phase column and UV detection at characteristic wavelength. |
| Color Strength | Reflectance Spectrophotometry | Measures relative color intensity by comparing reflectance of sample vs standard under D65 illuminant. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution based on angular dependence of scattered laser light intensity. |
| Moisture Content | Karl Fischer Titration | Measures water content via stoichiometric reaction between water, iodine, and sulfur dioxide in methanol/pyridine medium. |
| 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 | Quantifies elemental concentrations by measuring atomic emission intensities after plasma atomization and excitation. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents using gas chromatographic separation and flame ionization detection. |
| pH of Aqueous Extract | Potentiometric Titration | Measures hydrogen ion activity in aqueous suspension using calibrated pH electrode. |
| Bulk Density | ASTM D1895 Method A | Determines mass per unit volume of freely settled powder in standardized cylinder. |
| Heat Stability | Thermogravimetric Analysis (TGA) | Evaluates weight loss profile under controlled heating to assess decomposition onset temperature. |
| Lightfastness | Xenon Arc Weathering (ISO 105-B02) | Assesses color change after exposure to controlled xenon lamp irradiation simulating daylight. |
| Migration Resistance | Solvent Rub Test (ISO 2812-1) | Evaluates surface transfer resistance by mechanical rubbing with specified solvent-saturated cloth. |
