Surface-treated pigments for waterborne and solvent-borne architectural emulsions, exterior masonry paints, and decorative coatings.
Discuss Your ApplicationArchitectural paint pigments must deliver clean color, strong opacity at low loadings, freeze-thaw stability through paint shelf life, and 5+ years of exterior color retention. They must work in waterborne acrylic emulsions (the dominant chemistry for residential paint) and solvent-borne alkyd systems (for premium finishes and trim).
Recommended architectural paint pigments by color: yellows — PY74 (everyday), PY83 (high heat resistance), PY154 (premium benzimidazolone for outdoor); reds — PR112 (everyday warm red), PR170 (premium red), PR122 (quinacridone magenta); oranges — PO5, PO13, PO34 (azo oranges), PO64 (benzimidazolone for outdoor); blues — PB15:3 (process blue) and PB15:1 (warm blue); greens — PG7 and PG36; blacks — carbon black paste.
Surface treatment matters: untreated pigments work in solvent-borne alkyd paints but flocculate or settle in waterborne emulsions. Surface-treated grades (with hydrophilic surface chemistry) disperse cleanly in both, simplifying inventory for paint shops handling both chemistries.
For exterior masonry paints exposed to alkaline cement substrates, choose alkali-resistant grades: PY83, PY154, PR48:2, PR48:4, PB15:3, PG7. Standard architectural pigments may shift shade or fade rapidly when applied directly over fresh cement.
Exterior architectural paints require Blue Wool lightfastness 7-8 (ISO 105-B02). Recommended: PY154 (benzimidazolone yellow), PY83 (diarylide HR yellow), PR122 (quinacridone red), PR254 (DPP red), PB15:3 (phthalocyanine blue), PG7 (phthalocyanine green). Avoid standard azo grades like PY3, PY12, PY14 for exterior use as they fade within 1-2 years.
Phthalocyanine grades (PB15:3, PB15:4, PG7, PG36) are inherently alkali-resistant and work directly over fresh cement. Iron oxides (PR101, PY42) are also fully alkali-stable. For organic yellow and red shades over cement, choose alkali-treated grades or apply over a primer to isolate the pigment from cement alkalinity.
Yes. We supply surface-treated organic pigments specifically engineered for clean dispersion in waterborne acrylic emulsions. These grades won't flocculate, settle, or shift shade through paint shelf life. Standard untreated pigments work better in solvent-borne alkyd systems; ask for the appropriate variant when ordering.
