Pigments are the functional heart of every paint and coating. They provide hiding power, colour, UV protection, anti-corrosion properties, and in some cases fire resistance. For paint and coating manufacturers across the UAE and Saudi Arabia, selecting the right pigment system — and sourcing it reliably and cost-effectively — is one of the most consequential decisions in the formulation and procurement process.
This guide covers the principal pigment categories used in GCC paint manufacturing, with selection guidance specific to the region's climate, regulatory environment, and market requirements.
The Three Pigment Categories in Industrial Coatings
1. White Pigments — Titanium Dioxide (TiO2)
Titanium dioxide (TiO2) is the most important pigment in all of paint manufacturing, responsible for virtually all hiding power (opacity) in architectural and industrial coatings. No other white pigment comes close to TiO2 in refractive index (2.7-2.9), hiding power efficiency, or durability.
Two crystal forms are used commercially:
- Rutile TiO2 — the dominant form for industrial and exterior architectural coatings. Higher refractive index (2.73), better UV resistance, and chalk resistance. Produced by both sulphate and chloride processes — chloride-process rutile has the highest quality and is strongly recommended for exterior GCC applications. See our rutile vs anatase comparison →
- Anatase TiO2 — lower refractive index (2.55), more self-cleaning (photocatalytic) but chalks heavily in UV — which makes it unsuitable for exterior use in the GCC's intense sunlight. Used in interior paints where cost optimisation is prioritised.
Typical TiO2 loading: 15-22% by weight in exterior emulsion paint; 18-25% in high-hiding solvent-based alkyd; 10-20% in industrial primers (where extenders carry some of the PVC load).
2. Inorganic Coloured Pigments
Inorganic pigments provide outstanding lightfastness, heat resistance, and chemical resistance at relatively low cost. The most important families in GCC industrial coatings:
| Pigment | Colour | CAS | Lightfastness | Key GCC Applications |
|---|---|---|---|---|
| Iron Oxide Red (Fe₂O₃) | Red/Brown | 1309-37-1 | Excellent (8/8) | Primers, rust-inhibiting coatings, coloured concrete |
| Iron Oxide Yellow (FeO(OH)) | Yellow/Ochre | 51274-00-1 | Very Good (7/8) | Architectural paints, road markings |
| Iron Oxide Black (Fe₃O₄) | Black | 1317-61-9 | Excellent (8/8) | Primers, maintenance coatings |
| Iron Oxide Orange | Orange | 51274-00-1 | Very Good (7/8) | Traffic markings, industrial colours |
| Carbon Black | Black | 1333-86-4 | Excellent (8/8) | UV absorption, dark tints, bituminous coatings |
| Zinc Phosphate | White | 7779-90-0 | N/A (functional) | Anti-corrosion primer pigment |
| Micronised Zinc (Zn) | Grey | 7440-66-6 | N/A (functional) | Zinc-rich primers for steel (see our zinc primer guide) |
3. Organic Coloured Pigments
Organic pigments offer higher colour strength and vividness than inorganic alternatives but generally have lower heat stability and lightfastness. Selection in the GCC context:
- Phthalocyanine Blue (PB15) and Green (PG7) — the most lightfast organic pigments (7-8/8 blue wool). Used in architectural and industrial topcoats. Good UV stability.
- Diazo Yellow and Orange — moderate lightfastness (5-6/8). Suitable for interior applications, traffic road markings (with UV stabiliser package), and short-service coatings. Avoid for long-term GCC exterior exposure without rigorous lightfastness testing.
- Quinacridone Red and Violet — high lightfastness (7-8/8). Used in automotive and high-performance architectural coatings.
- DPP (Diketopyrrolopyrrole) Red — premium high-lightfastness red for automotive OEM and high-durability architectural applications.
Extender Pigments — Reducing Cost Without Sacrificing Performance
Extender pigments (calcium carbonate, talc, kaolin, barium sulfate, calcium silicate) are inorganic minerals used to supplement TiO2 and coloured pigments. In the GCC market they serve critical functions:
- Calcium carbonate (chalk/limestone): Most widely used extender in GCC architectural paints. Provides body, improves scrub resistance at higher PVC, and reduces cost. Available locally in Saudi Arabia from natural deposits.
- Talc: Improves sag resistance, settlement resistance, and provides a silky surface texture. Used in interior and exterior emulsion paints.
- Kaolin (calcined): Improves scrub resistance and barrier properties. Used in high-quality exterior emulsions.
- Barium sulfate (Barytes): High specific gravity (4.4-4.5) provides excellent chemical and abrasion resistance. Widely used in industrial and automotive primers.
Pigment Dispersion in GCC Climates
Pigment dispersion — breaking aggregates into primary particles and stabilising them in the liquid phase — is a critical process step. In the GCC, high ambient temperatures accelerate flocculation and settling during storage, making the choice of dispersing agent especially important. Key considerations:
- For water-based systems: high-performance polymeric dispersants (e.g. acrylic acid copolymers) at 0.2-1.5% on pigment weight provide best stability at 40-50°C storage temperatures
- For solvent-based systems: hyperdispersants with anchoring groups matched to the pigment surface chemistry
- Grinding fineness: typically ≤25 μm Hegman grind for quality architectural finishes; ≤15 μm for industrial coatings

SABER and Regulatory Compliance for Pigments in Saudi Arabia
When importing pigment raw materials into Saudi Arabia, check whether the specific product falls under a SABER-regulated category. Lead, cadmium, chromate, and mercury-based pigments are restricted or prohibited under SASO technical regulations and international legislation. Read our SABER certification guide →
