class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">The red-shade \u03b1-types (PB 15:1, PB 15:2) are widely preferred in liquid coatings due to their vivid tone, high tinting strength, and ease of dispersion.<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\">4. How to Evaluate Dispersion Quality in Coating Pigment Selection and Application<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Formulators use direct and indirect methods to inspect dispersion fineness:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Hegman Grind Gage Method<\/strong>: A quick test for liquid systems. Material is drawn across a dual channel sloped from 100 to 0 microns. The depth at which dense particle specks appear marks the dispersion level. A rating of <strong>7 or higher<\/strong> (approximately &lt;15 um) indicates effective dispersion.<\/li>\n\n\n\n<li><strong>Optical Microscopy<\/strong>: Enables direct inspection of particle size, distribution, and flocculation, though resolution is limited to roughly 2 microns.<\/li>\n\n\n\n<li><strong>Electron Microscopy (SEM\/TEM)<\/strong>: Delivers high resolution to observe primary particle morphology. However, equipment is costly, sample preparation is lengthy, and dry-state analysis is required.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">5. Solvent Resistance Considerations in Coating Pigment Selection and Application<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Solvent resistance measures a pigment&#8217;s <strong>ability to resist dissolution in organic solvents<\/strong>, avoiding bleed or staining when exposed to solvent-borne resins during manufacturing or post-application contact with cleaners, gasoline, or lubricants.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Inorganic pigments and complex organic structures (e.g., DPP, quinacridones) possess excellent solvent resistance. Lower-grade organic pigments tend to bleed when exposed to strong polar solvents like MEK, ethyl acetate, or xylene. Common test solvents include water, mineral spirits, toluene, xylene, MEK, ethanol, ethyl acetate, diethylene glycol, and trichloroethylene.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">6. Lightfastness vs. Weatherability in Coating Pigment Selection and Application<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>\u0645\u0642\u0627\u0648\u0645\u0629 \u0627\u0644\u062a\u0644\u0627\u0634\u064a \u062a\u062d\u062a \u062a\u0623\u062b\u064a\u0631 \u0627\u0644\u0636\u0648\u0621<\/strong>: Evaluates a pigment&#8217;s technical ability to resist fading or discoloration caused <strong>solely by light exposure (specifically UV radiation)<\/strong>.<\/li>\n\n\n\n<li><strong>\u0645\u0642\u0627\u0648\u0645\u0629 \u0627\u0644\u0639\u0648\u0627\u0645\u0644 \u0627\u0644\u062c\u0648\u064a\u0629<\/strong>: A comprehensive metric reflecting performance under combined outdoor variables, including <strong>UV radiation, temperature fluctuations, moisture\/humidity, and atmospheric pollutants<\/strong>. Weatherability is evaluated via Florida outdoor exposure testing (tilted 5\u00b0 south for 12+ months) or accelerated xenon arc weathering chambers.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">7. Understanding Oil Absorption for Coating Pigment Selection and Application<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Oil absorption indicates the minimum quantity of refined linseed oil required to thoroughly wet 100 grams of dry pigment powder into a cohesive paste (g\/100g).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This parameter directly correlates with <strong>specific surface area and porosity<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Low Oil Absorption<\/strong> \u2192 Smaller specific surface area \u2192  Easier resin wetting \u2192  Lower system viscosity and superior flow properties.<\/li>\n\n\n\n<li><strong>High Oil Absorption<\/strong> \u2192  Larger surface area \u2192  Higher demand for wetting\/dispersing agents and resin binders.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">8. Improving Hiding Power Through Smart Coating Pigment Selection and Application<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For pigments with low light-absorption capabilities (such as bright organic yellows and reds), hiding power can be enhanced by:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>Blending High-Hiding Inorganic Pigments<\/strong>: Incorporating TiO2 (refractive index \u2248 2.5 vs. \u2248 1.6 for organic pigments) or iron oxides to maximize light scattering.<\/li>\n\n\n\n<li><strong>Synergistic Carbon Black Addition<\/strong>: Adding trace amounts of carbon black absorbs light across all wavelengths, compensating for the weak scattering of organic red or bright pigments and raising overall opacity without dulling the shade excessively.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">9. Preventing Separation Issues in Coating Pigment Selection and Application<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When two or more pigments exhibit differing mobilities within a film, pigment separation occurs:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Flooding<\/strong>: Involves <strong>vertical separation<\/strong> of pigment components through the film thickness. Pigment concentration remains uniform across the horizontal plane, but vertical variations create surface shade inconsistency.<\/li>\n\n\n\n<li><strong>Floating<\/strong>: Refers to <strong>horizontal separation<\/strong> of pigments. The surface displays uniform color horizontally, but the surface color differs noticeably from the underlying wet coat (visible via a rub-out test).<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">10. Hiding Power Metrics in Coating Pigment Selection and Application<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Hiding power measures a pigmented coating&#8217;s capacity to conceal the substrate&#8217;s color or underlying pattern when applied at a specific film thickness, expressed in g\/m2.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Black Pigments<\/strong>: Achieve opacity through <strong>total light absorption<\/strong>.<\/li>\n\n\n\n<li><strong>Chromatic Pigments<\/strong>: Achieve hiding by <strong>selectively absorbing<\/strong> specific light wavelengths.<\/li>\n\n\n\n<li><strong>White Pigments<\/strong>: Do not absorb light; hiding relies entirely on <strong>strong light scattering<\/strong>.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">11. The 4 Dispersion Stages in Coating Pigment Selection and Application<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Pigment dispersion involves stabilizing solid pigment particles uniformly within a fluid medium through four steps:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>Wetting<\/strong>: Solvent or water displaces entrapped air on the pigment surface, assisted by wetting agents to soften particle aggregates.<\/li>\n\n\n\n<li><strong>Deagglomeration<\/strong>: Mechanical shear, impact, and attrition forces from grinding equipment break pigment agglomerates down to primary particles.<\/li>\n\n\n\n<li><strong>Distribution<\/strong>: Primary particles are distributed evenly throughout the liquid resin matrix.<\/li>\n\n\n\n<li><strong>Stabilization<\/strong>: Dispersants provide electrostatic repulsion or steric hindrance to prevent re-agglomeration.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">12. Reagglomeration vs. Flocculation in Coating Pigment Selection and Application<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Reagglomeration<\/strong>: Pigment particles lose their protective resin film and fuse back together into dense, hard clusters that require high mechanical shear to break apart again.<\/li>\n\n\n\n<li><strong>Flocculation<\/strong>: Individual pigment particles retain their adsorbed resin layer but form <strong>loose, temporary clusters<\/strong> due to attractive interparticle forces; low shear stress easily breaks these clusters apart.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">13. Testing Floating and Flooding in Coating Pigment Selection and Application<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Common industry diagnostic tests include:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>Rub-out Test<\/strong>: During the flash-off period (when the film is partially dry), a section of the coat is rubbed with a finger. A distinct color difference between the rubbed area and the unrubbed film indicates severe floating, flooding, or flocculation.<\/li>\n\n\n\n<li><strong>Spray vs. Drawdown Comparison<\/strong>: Comparing shade differences between a sprayed panel and a wire-rod drawdown panel.<\/li>\n\n\n\n<li><strong>Glass Plate Drawdown<\/strong>: Inspecting drawdowns on glass plates from both the top and reverse sides to observe color uniformity.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">14. Infrared Camouflage Pigment Selection and Application Guidelines<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">IR camouflage coatings must match the background shade in the visible spectrum (400\u2013700 nm) while mimicking natural environmental reflection curves (foliage, soil) in the <strong>near-infrared region (700\u20131200 nm)<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Suitable camouflage pigments include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Green\/Black<\/strong>: Pigment Green 17, PG 26, PBk 30, Chromium Oxide Green.<\/li>\n\n\n\n<li><strong>Yellow\/Violet<\/strong>: Pigment Yellow 119, Carbazole Violet.<\/li>\n\n\n\n<li><strong>Inorganic Bases<\/strong>: High-purity synthetic iron oxide pigment grades.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">15. Quantitative Hiding Power Measurement in Coating Pigment Selection and Application<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Hiding power is quantified using standard <strong>black-and-white opacity charts<\/strong>:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>A wet coating film of defined thickness is drawn down over a black-and-white test chart.<\/li>\n\n\n\n<li>After drying, spectrophotometric reflectance values (Yblack \/ Ywhite) are measured. Complete hiding is recognized when the contrast ratio reaches 0.98.<\/li>\n\n\n\n<li>The weight of dry paint required per square meter (g\/m2) to completely obliterate the background contrast is calculated under D65 standard daylight conditions.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">System Synergy &amp; Dispersant Optimization for Coating Pigment Selection and Application<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Proper <strong>\u0627\u062e\u062a\u064a\u0627\u0631 \u0623\u0635\u0628\u0627\u063a \u0627\u0644\u0637\u0644\u0627\u0621 \u0648\u0637\u0631\u0642 \u062a\u0637\u0628\u064a\u0642\u0647\u0627<\/strong> must be paired with optimized hyperdispersant chemistry to prevent flocculation, floating, or settling during storage<sup><\/sup>.
