TiO2 procurement guidance by buyer type
Different industries face different TiO2 procurement priorities. Architectural paint manufacturers optimize cost; automotive Tier-1 suppliers prioritize qualification rigor; cosmetic brands navigate regulatory compliance. Each page below covers business context, procurement challenges, recommended SEMITI grades, and typical qualification cycles for that buyer type.
Coatings industry
Architectural paint is TiO2's largest end-market — 30%+ of global demand. Cost optimization and supply continuity are the dominant procurement priorities.
Industrial coatings demand durable rutile TiO2 with 10–30 year service life. Procurement priorities are durability proof + supply stability over pure cost.
Automotive paint demands the most stringent TiO2 qualification — color match, acid resistance, OEM approval. SEMITI 880 is engineered for this niche.
Coil coatings demand 15–25 year outdoor durability. SEMITI 826D is the workhorse — Tronox CR-826 equivalent.
Powder coatings demand thermal stability for twin-screw extrusion + 200°C cure. Chloride rutile (SEMITI 706, 826D) is essential.
Marine coatings face salt spray, UV, biofouling. SEMITI 826D + zinc-rich primers are the typical durable-rutile choice.
Plastics industry
Masterbatch producers run high-load TiO2 compounds (50–70%). Thermal stability and clean extrusion are top priorities.
Outdoor PVC profile demands SEMITI 2160 or 2190 — Kronos 2160 / 2190 equivalents for 10–20 year service.
PE/PP film TiO2 must disperse cleanly without fish-eye and resist HALS antagonism in outdoor agricultural films.
Food packaging plastics use FDA-compliant SEMITI grades. Heavy metals tightly controlled, migration documentation provided.
Inks & paper
Offset ink demands fast bead-mill dispersion and tight color spec. SEMITI INK-1 is the ink-grade choice.
Flexo and gravure inks demand anti-screen-blinding TiO2. SEMITI INK-1 prevents anilox blinding at high loading.
Decor paper runs 25–40% TiO2 loading. SEMITI PAPER-D is the workhorse, Ti-Pure R-104 equivalent.
Specialty papers use 5–15% TiO2 — SEMITI A100 anatase is typically the cost-optimal choice.
Cosmetics & rubber
Mineral sunscreen brands need nano TiO2 with broad-spectrum protection + reef-safe regulatory compliance. SEMITI NANO-30 delivers at half the cost of Kobo TTO-S-3.
Rubber compounding favors anatase (SEMITI A200) — soft crystal protects Banbury equipment from wear.
Tire white sidewall uses 5–15 phr anatase TiO2. SEMITI A200 is the tire-grade choice — Ishihara TIPAQUE A-100 alternative.
Synthetic fiber delustering uses 0.3–0.5% anatase. SEMITI A100 / A200 with low metallic impurity prevents spinneret fouling.
Specialty & trade
Ceramic glaze uses 3–7% anatase for opacification. SEMITI A100 fires cleanly at 1100–1180°C.
Food packaging plastics use FDA-compliant SEMITI grades. Heavy metals tightly controlled, migration documentation provided.
Pharmaceutical packaging demands USP / EP / JP pharmacopeial-grade TiO2 with batch-by-batch heavy metal testing.
SEMITI partners with regional chemical traders and distributors — multi-grade portfolio, marketing support, flexible volume tiers.
Construction materials use 1–5% TiO2 for whitening — cost-optimized SEMITI 298 sulfate covers most applications.
White adhesives and sealants use 5–15% TiO2 for opacity. SEMITI 996 / 902 with proper surface treatment matches sealant chemistry.
International trading houses use SEMITI for multi-region distribution, contract sourcing for major paint companies, and project-based industrial coating supply.
