This guide explains what PY83 is, how labs actually measure \u201cfastness,\u201d where it typically excels, and what procurement teams should request from suppliers to de\u2011risk selection.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Pigment Yellow 83: identity and chemistry<\/h2>\n\n\n\n<p>PY83 is formally indexed as C.I. Pigment Yellow 83 (C.I. 21108), a diarylide (disazo) organic pigment synthesized from biphenyl\u2011based diarylide coupling components. Its molecular formula is C36H32Cl4N6O8, with common procurement identifiers CAS 5567\u201115\u20117 and EC\/EINECS 226\u2011939\u20118. Authoritative registries include the NIH\u2019s PubChem entry for C.I. Pigment Yellow 83, which lists structure and identifiers, and the European Chemicals Agency public search portal used for REACH lookups:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><p>PubChem identity &amp; structure reference: <a target=\"_blank\" rel=\"nofollow noopener\" class=\"link\" href=\"https:\/\/pubchem.ncbi.nlm.nih.gov\/compound\/21733\"><strong>PubChem\u2019s C.I.

Particle size control and surface treatment can push grades toward higher transparency (inks, metallic finishes) or higher opacity and durability (industrial coatings). Like other diarylides, long\u2011term high\u2011heat exposure in polymers can risk color change or decomposition; conservative processing windows are addressed below.<\/p>\n\n\n\n<figure class=\"wp-block-table\">\n<table class=\"has-fixed-layout\">\n<colgroup><col \/><col \/><col \/><\/colgroup><tbody><tr><th colspan=\"1\" rowspan=\"1\"><p>Identifier<\/p><\/th><th colspan=\"1\" rowspan=\"1\"><p>\u0391\u03be\u03af\u03b1<\/p><\/th><th colspan=\"1\" rowspan=\"1\"><p>Typical use in procurement<\/p><\/th><\/tr><tr><td colspan=\"1\" rowspan=\"1\"><p>CAS<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>5567\u201115\u20117<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>Contracts, SDS\/TDS cross\u2011checks<\/p><\/td><\/tr><tr><td colspan=\"1\" rowspan=\"1\"><p>EC\/EINECS<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>226\u2011939\u20118<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>REACH portal queries<\/p><\/td><\/tr><tr><td colspan=\"1\" rowspan=\"1\"><p>Color Index<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>C.I. 21108<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>Shade family confirmation<\/p><\/td><\/tr><tr><td colspan=\"1\" rowspan=\"1\"><p>Formula<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>C36H32Cl4N6O8<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>Identity confirmation in databases<\/p><\/td><\/tr><\/tbody>\n<\/table>\n<\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">How labs report \u201cfastness\u201d: the methods that matter<\/h2>\n\n\n\n<p>Lightfastness (resistance to fading) is commonly communicated using the Blue Wool reference scale (BW 1\u20138) within xenon\u2011arc exposure methods. In textiles, the canonical method is ISO 105\u2011B02; pigment suppliers frequently borrow the same BW language when summarizing lightfastness for inks, plastics, and coatings even if the exact apparatus or substrate differs. Two concise, authoritative starting points are the <a target=\"_blank\" rel=\"nofollow noopener\" class=\"link\" href=\"https:\/\/www.iso.org\/standard\/41372.html\"><strong>ISO 105\u2011B02 overview page<\/strong><\/a> and the Society of Dyers and Colourists\u2019 <a target=\"_blank\" rel=\"nofollow noopener\" class=\"link\" href=\"https:\/\/sdc.org.uk\/wp-content\/uploads\/2022\/05\/1995JS220.pdf\"><strong>historical\/technical note on the Blue Wool Scale<\/strong><\/a>. In procurement terms, BW5 is often treated as a minimal indoor baseline where some fading is acceptable, BW6 as a \u201cgood\u201d level for many general applications, and BW7\u20138 as very good to excellent for demanding or longer\u2011life uses\u2014always method, substrate, and concentration dependent.<\/p>\n\n\n\n<p>Solvent and rub resistance in coatings and inks is typically screened by double\u2011rub practices. For organic coatings, industry commonly references ASTM D5402, which specifies test solvents (e.g., MEK), cloth type, test load, and how to count double rubs. When you add solvent\u2011resistance language to a purchase spec, cite the method and parameters rather than only saying \u201cMEK resistant.\u201d For details, see: <a target=\"_blank\" rel=\"nofollow noopener\" class=\"link\" href=\"https:\/\/www.astm.org\/d5402-15.html\"><strong>ASTM D5402 solvent rub practice for organic coatings<\/strong><\/a>.<\/p>\n\n\n\n<p>Note on typical vendor data: Some public technical data sheets communicate lightfastness qualitatively or in matrix\u2011agnostic tables. For example, an artist\u2011media data sheet lists PY83 lightfastness as BW5 in full shade and BW8 at 1\/3 SD reductions, which illustrates how concentration affects ratings but is not an end\u2011use matrix value. See this illustrative reference: <a target=\"_blank\" rel=\"nofollow noopener\" class=\"link\" href=\"https:\/\/www.kremer-pigmente.com\/elements\/resources\/products\/files\/23380e.pdf\"><strong>Kremer Pigmente PY83 data sheet<\/strong><\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">PY83 properties by application<\/h2>\n\n\n\n<p>Because performance depends on grade, dispersion state, binder\/polymer, and concentration, treat the following as typical windows to guide screening\u2014not as universal guarantees. Always confirm grade\u2011specific data in current TDS and your lab trials.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Inks (offset, gravure, flexo, screen; solvent\u2011based, water\u2011based, UV)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><p>Shade\/transparency: PY83 is a benchmark red\u2011shade yellow. Finer particle sizes and resin\u2011treated grades boost transparency for metallic inks and high\u2011gloss prints; coarser or less\u2011treated variants improve opacity and hiding.<\/p><\/li><li><p>Dispersion: Achieve stable dispersion with appropriate vehicles\/wetting agents; control millbase viscosity and aim for a high, clean grind (e.g., Hegman 7+ in many systems). Watch for flocculation in low\u2011polarity solvents; use dispersant packages compatible with the resin.<\/p><\/li><li><p>Fastness expectations: Indoor graphics typically accept BW5\u20136 equivalents when printed at practical film weights; outdoor or long\u2011term labels\/posters often require BW6+ targets and weathering checks.<\/p><\/li><li><p>Acceptance tests to specify: Xenon\u2011arc exposure with Blue Wool references; solvent rub per ASTM D5402 where relevant; abrasion tests as needed.<\/p><\/li>\n<\/ul>\n\n\n\n<p>Micro\u2011example (solvent\u2011based gravure ink, red\u2011shade yellow): You need a transparent red\u2011shade PY83 with strong tinting and stable viscosity. Shortlist grades offered for solvent systems; request drawdowns at equal pigment volume concentration and BW references from xenon\u2011arc tests.

A vendor TDS example specifies 199\u202f\u00b0C stability for PY83 in HDPE and paints; use this as a conservative screening target and verify in your polymer and residence\u2011time profile.

Screen with contact migration tests under your plasticizer package and service temperature.<\/p><\/li><li><p>Loading and form: Work with powder pigments, predispersed concentrates, or masterbatch depending on the line. For HDPE\/PP, small, well\u2011stabilized particles reduce plate\u2011out and improve color development.

In metallic or effect coatings, transparent grades maintain flop and metallic sparkle.<\/p><\/li><li><p>Weathering and recoat: Specify lightfastness targets using Blue Wool language and define recoat resistance where multi\u2011layer stacks are used to avoid bleeding\/floating. For solvent resistance, reference ASTM D5402 with a defined solvent (e.g., MEK) and a target number of double rubs.<\/p><\/li><li><p>Bake windows: For stoving\/industrial bakes, qualify color stability versus your bake schedule; diarylides can shift if overheated or over\u2011dwelled.

Some commercial grades may be formulated to meet applicable regulations, but approvals are grade\u2011 and use\u2011specific. Always verify with supplier declarations of conformity and perform migration testing under your end\u2011use conditions.<\/p><\/li><li><p>What Blue Wool number should I target? For many indoor applications, BW6 is a practical baseline; demanding outdoor or high\u2011exposure uses may require BW7\u20138 targets and method\u2011appropriate weathering.<\/p><\/li><li><p>Can PY83 handle 250\u202f\u00b0C processing? Short peaks might be tolerated depending on grade and dwell time, but diarylides are generally validated around 200\u202f\u00b0C for sustained processing in polyolefins. Confirm with plaques tested to your thermal profile.<\/p><\/li><li><p>How do I choose between PY83 and PY74? PY83 leans red and is offered in more opaque industrial variants; PY74 is typically cleaner\/greener and often more transparent.
