Titanium Chelates Supplier — 8-Grade Portfolio as TYZOR Alternatives
Eight stabilized organotitanium grades covering waterborne, solventborne, and reactive applications — qualified TYZOR-equivalent supply from China's titanium chemical belt.

Supply Chain Position: From TiCl₄ to Finished Chelate
Titanium chelates sit three steps downstream from ilmenite ore: TiCl₄ → titanium alkoxide → chelation with target ligand. SEMITECH sources from integrated Sichuan producers controlling the alkoxide step. DuPont's 2021 exit from several TYZOR SKUs tightened Western supply; SEMITECH has supported 60+ accounts since 2022.
8-Grade Portfolio: Selection by Ligand Chemistry
Four ligand families control hydrolytic stability, pH window, and solvent compatibility. Selecting by ligand family rather than trade name reduces substitution risk.
- TiAA (≡ TYZOR AA) — Ti 10–11%, acetylacetonate in IPA. Solventborne crosslinker for polyesters and epoxies, 20–150 °C.
- Ti Lactate (≡ TYZOR LA) — Ti 9–10%, water-miscible, pH 4–8. Printing inks and waterborne primers.
- Ti TEA (≡ TYZOR TEA) — Ti 8–9%, triethanolamine, water-dilutable, pH 5–9. Glass/metal adhesion promoter.
- Ti Glycolate — Ti 11–12%, water-compatible. Higher Ti loading than lactate grade.
- Ti Citrate (≡ TYZOR CLA) — Ti 7–8%, highly water-soluble. Food-processing and regulated textile coatings.
- Ti Phosphate — Ti 8–10%, water-soluble. Corrosion-inhibiting primers and conversion coatings.
- K-Titanyl Oxalate — ≥99% purity, white crystalline. Electroplating brightener, PCB finish, textile mordant.
- TiOSO₄ (Titanyl Sulfate) — Ti 16–17%, aqueous solution, pH 1–3. TiO₂ precursor and textile auxiliary.

Downstream Demand: Four End-Markets, One Portfolio
Coatings and adhesives account for ~55% of consumption, followed by inks (18%), textiles (12%), and electronics (15%). EV battery electrode binder development is driving incremental demand at 20–25% CAGR through 2027.
TYZOR Drop-In Qualification: Analytical and Performance Data
SEMITECH supplies CoA data mapped directly to TYZOR product sheets: Ti assay, viscosity, density, APHA color, pH, and flash point. TiAA gel time confirms performance parity within ±8% vs. TYZOR AA. Ti lactate achieves Konig hardness within ±5% of TYZOR LA reference.

FAQ
+Which SEMITECH grade directly replaces DuPont TYZOR AA?
SEMITECH TiAA: Ti 10–11%, acetylacetonate in IPA, density 1.06–1.08 g/cm³. Gel-time parity within ±8% vs. TYZOR AA.
+What is the MOQ and lead time for titanium chelate orders?
Sample MOQ 25 kg; commercial orders from 200 kg. Stocked grades ship ex-warehouse Shanghai in 5–7 days. K-titanyl oxalate and TiOSO₄ require 3–4 weeks above 500 kg.
+How does Ti lactate differ from Ti glycolate in waterborne formulations?
Ti lactate offers broader pH tolerance (4–8) and higher hydrolytic stability. Ti glycolate's higher Ti content (11–12%) allows lower addition levels in tightly controlled systems.
+What caused the TYZOR supply gap after 2021?
DuPont divested specialty titanate lines during restructuring; several TYZOR SKUs were discontinued or transferred to Dorf Ketal with extended lead times.
+Can titanium chelates serve as antimony-free catalysts in polyester synthesis?
Yes. TiAA and Ti glycolate function at 0.01–0.05 wt% on monomer, replacing Sb₂O₃ for food-packaging compliance.
+Is K-titanyl oxalate used differently from liquid chelate grades?
K-titanyl oxalate is a crystalline solid for electroplating and textile mordanting — not a crosslinker or catalyst. Use liquid chelates (TiAA, Ti lactate) for coatings.
