Applications
- Premium Architectural Wall Paints UAE & Saudi Arabia — Chloride grade TiO2 is the standard white pigment in premium emulsion paints for UAE and Saudi Arabia residential, commercial, and hospitality projects. Its superior UV durability prevents chalking and grey discolouration under intense GCC solar radiation — critical for exterior paints exposed to UAE's UV Index 11+ summer conditions.
- Industrial & Protective Coatings — Used in two-component epoxy and polyurethane topcoats for structural steel, pipelines, and industrial facilities across GCC.
- Decorative & Architectural Coatings for Vision 2030 Projects — Saudi Arabia's mega-projects — NEOM, Red Sea, Diriyah, Qiddiya — specify premium coating raw materials meeting SASO and international quality benchmarks. Chloride grade TiO2 meets and exceeds these specifications with full documentation.
- Masterbatch & Plastics — Premium opacity and brightness for white and light-coloured plastic masterbatch, PVC, and polymer compounds used across GCC manufacturing.
- Powder Coatings — Excellent heat stability (up to 300°C) and consistent brightness in thermoset powder coatings for architectural aluminium, steel furniture, and industrial components.
- Printing Inks & Packaging — Used in white printing inks and packaging coatings for the UAE and Saudi Arabia FMCG and food packaging industry.
Key properties
- Refractive index 2.73 (rutile) — highest of any commercial white pigment
- Superior hiding power vs sulphate grade — fewer kg needed per litre of paint
- Chloride process: higher purity, more consistent particle morphology
- Al₂O₃ + ZrO₂ surface treatment — maximum weathering and chalking resistance
- Brightness Rd ≥ 95.0 — premium whiteness for GCC specifications
- Tinting strength ≥ 1,700 Reynolds — superior colour mixing performance
- No heavy metals — SASO and REACH compliant
- Compatible with all standard binder systems (acrylic, alkyd, epoxy, PU)
Usage and recommendations
Typical loading in architectural paint: 15–25% by weight. Higher loading above 25% causes PVC (pigment volume concentration) to exceed critical PVC — reducing gloss and barrier properties. Disperse thoroughly using high-speed disperser or bead mill — achieve full deagglomeration before letdown. Use adequate dispersant (polymeric or anionic type) at 0.5–2.0% on TiO2 weight. For Saudi architectural paints, set TiO2 content to reach the hiding power specified for the product. Contact Raykem for formulation guidance.

Storage and shelf life
Store in original sealed bags in a cool, dry warehouse (< 25°C, < 60% RH). TiO2 is non-hazardous but moisture can cause caking — keep sealed. No defined shelf life when stored correctly. Maintain FIFO stock rotation.
