Anticorrosive Pigment UAE & KSA Stock COA + SDS Supplied CIF / FOB Available Dubai & Riyadh

Anticorrosive Pigments — Zinc Phosphate, Zinc Dust & Zinc Chromate | UAE

Raykem supplies the key anticorrosive pigments used in protective primer and anti-corrosion coating formulations for the UAE and Saudi Arabia steel and infrastructure protection market. Our range covers Zinc Phosphate (the industry-standard environmentally acceptable anticorrosive), Zinc Dust (for cathodic protection in zinc-rich primers), and Zinc Chromate (for high-specification legacy systems). With the GCC's aggressive marine-industrial environment — salt spray, high temperatures, humidity cycling — proper anticorrosive primer specification is critical to coating system durability.

Applications — UAE, Saudi Arabia & GCC

Zinc-Rich Primers — Cathodic Protection

Zinc Dust is the active component in zinc-rich primers (organic and inorganic) providing galvanic/cathodic protection to structural steel. When steel is exposed through a coating defect, zinc dust sacrificially corrodes in preference to iron — the standard approach for corrosion protection of bridges, tanks, and structural steel across UAE and Saudi Arabia.

Zinc Phosphate Anti-Corrosion Primers

Zinc Phosphate is the environmentally preferred alternative to red lead and zinc chromate in corrosion-inhibiting primers. It forms insoluble zinc-iron phosphate complexes on the metal surface, providing passive corrosion inhibition. Used in primers for structural steel, pipelines, and industrial equipment across the GCC.

Offshore & Marine Anti-Corrosion Systems

Zinc-rich primers are the mandatory first coat in multi-layer corrosion protection systems for offshore platforms, marine structures, and coastal infrastructure in the Arabian Gulf — where salt spray, high humidity, and elevated temperatures demand maximum corrosion protection.

Pipeline & Tank Protection

Zinc phosphate epoxy primers are the industry standard first coat on internal and external surfaces of above-ground steel pipelines, storage tanks, and pressure vessels in UAE and Saudi Arabia oil, gas, and water infrastructure.

Zinc Chromate — High-Specification Legacy Systems

Zinc chromate provides excellent corrosion inhibition but is subject to Cr(VI) restrictions under REACH and some SASO specifications. For new systems in Saudi Arabia and UAE, zinc phosphate is the preferred replacement. Zinc chromate continues to be specified in some high-performance aerospace and military maintenance systems.

Usage & Recommendations

Zinc-rich epoxy primer (organic): use zinc dust at 80–85% by weight in dry film with two-component epoxy binder. Zinc phosphate epoxy primer: use at 10–20% PVC in two-component epoxy system. For Saudi Arabia SABER compliance: zinc phosphate is preferred over zinc chromate — confirm with your coatings specification and the relevant SASO standard. Zinc Dust is pyrophoric at fine particle sizes — handle as a flammable solid, maintain dry storage, avoid dust generation, and keep away from ignition sources. Contact Raykem for primer formulation guidance.

Storage & Shelf Life

Zinc Phosphate: store in sealed bags in a dry warehouse. Zinc Dust: store in sealed steel drums in a dry, cool, ventilated area away from ignition sources (classified as flammable solid UN3077). Zinc Chromate: store in sealed containers away from reducing agents. All: maintain dry conditions to prevent agglomeration and maintain product activity.

Frequently Asked Questions

Zinc phosphate is a passive corrosion inhibitor — it works by forming a protective barrier at the steel surface through the formation of insoluble phosphate complexes. It is used at 10–20% in primer formulations and provides good corrosion resistance. Zinc dust is an active cathodic protection pigment — metallic zinc sacrificially corrodes instead of the steel substrate. Zinc-rich primers use zinc dust at 80–85% in the dry film, providing the highest level of steel corrosion protection — equivalent to hot-dip galvanising in many service environments. The two systems are fundamentally different: zinc phosphate is in standard epoxy primers; zinc dust is in zinc-rich primers which are the most protective primer type available.

Zinc chromate contains Cr(VI), a Category 1A carcinogen regulated under REACH Annex XVII in Europe. In the UAE and Saudi Arabia, Cr(VI) pigments are not yet explicitly banned but are being phased out of specifications in line with international trends. Many UAE government and Aramco specifications now require Cr(VI)-free primers. Raykem recommends zinc phosphate-based primers for all new projects in the GCC. If your specification requires zinc chromate, contact our team for the relevant COA and regulatory documentation.
