LEARN / MATERIAL FUNCTION
Explore existing library materials with a source-linked pigment / colorant assignment.
These assignments describe a documented material function. The individual source may concern a particular supplier grade or application. Open a material’s evidence before using it in a formula.
24 source-linked library assignments. Matching a function does not establish compatibility, safety or a greener replacement.
CAS 21645-51-2
Recorded function: Flame-retardant mineral filler and reinforcing pigment
Aluminum hydroxide, also called alumina trihydrate (ATH), is used as a mineral flame retardant and smoke suppressant. Huber’s Hydral sheet also identifies uses in paper filling/coating, adhesive reinforcement and mild polishing applications. [Huber TDS]
CAS 13701-59-2
Recorded function: Corrosion-inhibiting pigment for coating formulations
Barium metaborate is used in corrosion-inhibiting coating pigments. Health Canada also records microbiocidal/microbiostatic uses in paints, paper products and industrial adhesives/coatings; this historical use evidence is not a current pesticide authorization.
CAS 7727-43-7
Recorded function: Mineral extender and functional filler for coatings and polymers
Barium sulfate is a dense inorganic pigment/extender and functional filler. TOR’s BARTEX material information identifies applications in paints, coatings, inks, adhesives, plastics, ceramics and rubber. Natural barite and chemically precipitated blanc fixe are distinct commercial forms.
CAS 14059-33-7
Recorded function: Yellow pigment / colorant
Source-defined general function; exact grade, application and formulation compatibility require review.
CAS See supplier composition
Recorded function: Inorganic pigment
Black iron-oxide powder pigment described for coloring construction materials. The entry is not a recommendation for an unlisted end use.
CAS 1344-95-2
Recorded function: Functional filler and corrosion-inhibiting pigment for primers
Calcium silicate covers commercially variable calcium salts of silicic acid. The archived Qemetica grade is calcium-modified silica used as an industrial additive. Its INHIBISIL 73 and 75 pigments are designed for corrosion protection in waterborne and solvent-borne primers. Other qualified grades can serve anti-caking uses, but the industrial grade here is not a food or pharmaceutical authorization. [Qemetica SDS; Qemetica brochure; JECFA]
CAS 1333-86-4
Recorded function: Filler / pigment research baseline
General carbon-black pigment function. The catalog baseline is not equated with any Cabot grade or surface treatment.
CAS 1333-88-6
Recorded function: Inorganic cobalt-aluminate pigment research reference
Cobalt aluminate is a blue inorganic pigment used for stable coloration in ceramic glazes, glass and coatings. Otto also identifies its exact-CAS C 2388 powder as a catalyst for nonoxidative propane dehydrogenation.
CAS 147-14-8
Recorded function: Copper-phthalocyanine blue pigment research reference
Copper phthalocyanine supplies intense blue coloration. Commercial phthalocyanine blue pigments are used in inks, coatings and plastics, while the archived Wako material is a practical laboratory grade with a minimum 85% assay. Alpha/beta crystal form, conditioning and surface treatment distinguish industrial pigment grades and are not specified for this Wako product. [Wako specification; DCL inks table]
CAS 6358-30-1
Recorded function: Organic violet pigment for water-based coatings and inks
Dioxazine violet is an organic violet pigment, commonly marketed as Pigment Violet 23. The exact-CAS HUPC UN8817 grade provides a reddish violet shade for water-based inks, textile printing and coatings. Grade selection determines dispersion and shade; the AstaTech laboratory reagent is not an interchangeable finished pigment formulation. [HUPC TDS; AstaTech SDS]

Recorded function: Opacifier
Supplier-grade/general function only; this does not establish compatibility with a starter formula, lower hazard, an EcoSafe rating or a verified environmental improvement.
CAS 81-77-6
Recorded function: Organic blue pigment for coatings, plastics and inks
Indanthrone is a durable blue pigment identified as Pigment Blue 60 / Vat Blue 4. DCL A3R is an alpha-form, transparent red-shade grade used for high-end color and effect shades. Its TDS supports solvent, heat, light and weather resistance; those are grade-specific typical values. [DCL TDS; DCL A3R product page]
