TiO2 by end-use — 12 industries we ship into every week
Different end-uses demand sharply different TiO2 grades — a coating-grade chloride rutile that performs in waterborne emulsion will fail in plastic masterbatch (moisture defects). An anatase that delivers brilliant whiteness in paper will chalk in 18 months on outdoor signage. Our applications pages map the right SEMITI grades to each use, with engineering notes (dosage, dispersion, pitfalls) drawn from formulator feedback in our customer base.
Coatings
Interior emulsion + exterior facade paints — the largest single TiO2 application by volume.
Heavy-duty protective coatings for steel structures, infrastructure, and machinery — demands durability and chemical resistance.
OEM and refinish topcoats with acid-rain resistance, clearcoat compatibility, and metallic effect support.
TGIC and TGIC-free polyester powder coatings — TiO2 must withstand 200°C extrusion + 180–200°C cure.
Pre-painted steel and aluminum coil for roofing, siding, appliances — durable rutile for 20+ year outdoor service.
Plastics
Window frames, fence boards, siding — UV-stable rutile to prevent yellowing and chalking over 10+ years outdoor.
White masterbatch concentrates for PE, PP, ABS, PS film and injection molding — typically 50–70% TiO2 loading.
Blown and cast film for packaging, agriculture, hygiene — low fish-eye, compatible with slip/antiblock packages.
