Pigment Yellow 12 for Water-Based Inks: Best Practices for SEA Formulators<\/h1>\n

If you formulate packaging inks or color plastics in Southeast Asia, you\u2019ve likely short\u2011listed Pigment Yellow 12 (PY12, diarylide yellow) for its dependable hue and attractive cost profile. This guide focuses on Pigment Yellow 12 for water\u2011based inks and plastics with practical, testable steps for stable low\u2011VOC dispersions, safe processing windows for PE\/PVC, and documentation that stands up to audits. Where standards or safety come into play, we cite authoritative sources so your QA team can validate quickly.<\/p>\n

Suppliers such as Honor Pigments are commonly selected when teams need diarylide options plus routine QA documentation; in this article, we reference their publicly available guides as neutral learning resources where helpful.<\/p>\n

What PY12 Is Good At\u2014and Where It Struggles<\/h2>\n

Pigment Yellow 12 is a classic diarylide, medium\u2011shade yellow used widely in inks and general\u2011purpose plastics. Typical physical data reported across open SDS\/TDS sources include density around 1.3\u20131.5 g\/cm\u00b3 and oil absorption roughly 30\u201350 g\/100 g; formulations should confirm actual values per grade. For a representative sheet, see the Suntone PY12 technical data sheet from Vipul Organics, which lists oil absorption and handling ranges that align with common practice (accessed 2026): https:\/\/vipulorganics.com\/Suntone%20Pigment%20Yellow%2012%20TDS\/Suntone%20Pigment%20Yellow%2012%20TDS.pdf<\/a><\/p>\n

On heat: public listings commonly position PY12 as suitable for short\u2011residence plastics processing around 180\u2013200\u00b0C, depending on grade and matrix. To stay conservative, set your baseline at the lower end and confirm on your line. One representative listing notes heat resistance \u201cup to 180\u00b0C,\u201d which tracks with many formulators\u2019 practice (2026): https:\/\/www.finelandchem.com\/pigment-yellow-12\/<\/a><\/p>\n

Positioning versus other diarylides: PY12 balances cost and color for many water\u2011based ink and PE film jobs. If you need higher heatfastness, deeper masstone, or cleaner tints under aggressive conditions (e.g., long residence >200\u00b0C or high\u2011solvent systems), other diarylide yellows such as Pigment Yellow 14 for solvent inks<\/a> and our Pigment Yellow 17 guide<\/a> \u2014 or entirely different chemistries \u2014 may be warranted. For coating applications, browse our coatings pigment selection<\/a>. For routine SEA paper packaging inks and LDPE\/LLDPE film under \u2264190\u2013195\u00b0C peaks, well\u2011chosen PY12 grades often deliver an acceptable performance\u2011to\u2011price ratio.<\/p>\n

Formulating Pigment Yellow 12 for Water\u2011Based Inks (low\u2011VOC friendly)<\/h2>\n

Pigment Yellow 12 for water\u2011based inks is a frequent choice in flexo\/gravure due to its shade and economics, but it\u2019s hydrophobic and prone to flocculation. Stable dispersions require the right surfactant mix, adequate shear, and disciplined QC.<\/p>\n
