Titanium Fine Chemicals — SEMITECH Product Portfolio
SEMITECH’s titanium fine chemicals portfolio — coupling agents, chelates, alkoxides, and functional TiO2 — sourced from qualified Chinese producers for global B2B buyers.
SEMITECH’s titanium fine chemicals portfolio spans four product families: titanate coupling agents, titanium chelates, titanium alkoxides, and functional TiO2. Each family serves distinct industrial segments — from polymer compounding and coatings to sol-gel processing and photocatalysis. SEMITECH consolidates supply from qualified Chinese specialty producers, delivering export documentation, COA, and technical support to B2B buyers across Asia, Europe, and the Americas under a single commercial relationship.
Titanate coupling agents improve adhesion and filler dispersion at the inorganic–organic interface in filled plastics, rubber, and coatings. SEMITECH stocks monoalkoxy, chelate, and neoalkoxy-type titanates. Standard loading levels run 0.5–2.0 wt% on filler weight. Products are packed in 25 kg drums or 200 kg IBC totes with lot-specific COA.
| Product | CAS No. | Ti Content (%) | Type | Key Application |
|---|---|---|---|---|
| Tetraisopropyl Titanate (TIPT) | 546-68-9 | ≥28.5 | Monoalkoxy | Polyester / PU coatings |
| Tetra-n-Butyl Titanate (TNBT) | 5593-70-4 | ≥20.5 | Monoalkoxy | Sol-gel / adhesives |
| Titanium Acetylacetonate | 14024-64-7 | ≥13.5 | Chelate | Crosslinker / inks |
| Neoalkoxy Titanate (KR-TTS equiv.) | 61417-49-0 | ≥7.0 | Neoalkoxy | Filled rubber / plastics |
Titanium chelates offer superior hydrolytic stability versus simple alkoxides, making them the preferred crosslinker choice in waterborne coatings, printing inks, and adhesive formulations. Titanium alkoxides — primarily TIPT and TNBT — serve as sol-gel precursors, ester-exchange catalysts, and surface-treatment agents. SEMITECH supplies both families in technical and high-purity reagent grades, with Ti content verified per lot by ICP-OES.
Beyond commodity pigment-grade TiO2, SEMITECH offers functional grades engineered for photocatalysis, UV absorption, and surface-active applications. Anatase nanoparticles (P25-equivalent, 20–30 nm) are stocked for photocatalytic coatings and air purification systems. Surface-treated hydrophobic grades serve polymer masterbatch and cosmetic formulations. MOQ starts at 25 kg; bulk pricing is available above 500 kg.
SEMITECH supplies four families: titanate coupling agents (TIPT, TNBT, KR-TTS equivalents), titanium chelates (acetylacetonate, triethanolamine-type), titanium alkoxides, and functional TiO2. All products include a COA with verified Ti% content and are available from 25 kg to IBC quantities.
Titanate coupling agents are typically applied at 0.5–2.0 wt% based on filler weight in filled polymer compounds. For waterborne coatings crosslinker use, effective dosage is 0.2–1.0% on total resin solids. SEMITECH’s technical team can recommend the appropriate grade and dosage for specific formulations.
Yes. SEMITECH stocks reagent-grade and electronic-grade TIPT (CAS 546-68-9) and TNBT (CAS 5593-70-4) at purity ≥99% confirmed by GC analysis. These grades meet requirements for sol-gel thin films, atomic layer deposition precursors, and catalyst synthesis applications.
Standard stock items ship within 7–10 business days ex-works China. MOQ is 25 kg for most grades; functional TiO2 nanoparticles start at 5 kg. Sea freight consolidation is available for mixed Ti product orders to reduce logistics cost. CIF and FOB pricing available on request.
China accounts for over 60% of global titanate coupling agent output, so supply continuity depends on domestic feedstock availability and trade policy. SEMITECH mitigates this by holding 3–6 months of buffer inventory on key grades and maintaining qualified relationships with multiple Chinese producers.
