Tyzor Organic Titanates and Zirconates

Tyzor are organic titanium and zirconium compounds that work as esterification and transesterification catalysts, crosslinkers, surface modifiers and adhesion promoters. Dorf Ketal offers more than 40 Tyzor grades: alkoxy titanates, titanium chelates and alkoxy zirconates.

Tyzor TPT: tetra-isopropyl titanate
Tyzor TnBT: tetra-n-butyl titanate
Tyzor NPZ: tetra-n-propyl zirconate
Tyzor AA-65, AA-75 and AA-105 titanium chelates

ACtivate and Tyzor PET and Polyolefin Catalysts

ACtivate are hydrolytically stable titanate catalysts for antimony-free PET bottle and film resins. Grades 420 and 422 serve PET, while grade 428 replaces organotin in polyester can coatings. Tyzor NPT is used with TPT and TnBT in Ziegler-Natta polyolefin production.

ACtivate 420 and 422: PET bottle and film resins
ACtivate 428: polyester can coatings
Tyzor NPT: stereospecific polyolefins
ACtivate PET: lower diethylene glycol content

Unilink and Clearlink Catalysts and Chain Extenders

Unilink covers zirconium and titanium catalysts and aromatic diamines for polyurethane and polyurea without mercury or tin. The 1000 series gives a fast cure similar to tin, the 2000 series a delayed cure similar to mercury. Clearlink 1000 and 1080 are aliphatic diamines for UV-stable coatings.

Unilink 1000: zirconium, fast cure profile
Unilink 2000: titanium, delayed cure profile
Unilink 4100, 4200 and 4230: aromatic diamines
Clearlink 1000 and 1080: aliphatic diamines

Catalysts and Adsorbents for Feedstock Treatment

Dorf Ketal catalysts and adsorbents serve feedstock treatment in syngas and catalytic reforming processes and hydrogenation and dehydrogenation in the fine chemicals industry. A special grade removes organic sulfur compounds from the liquid phase in hydrotreating.

Arsine removal and selective hydrogenation
Sulfur and chloride or halide removal
Desiccation and catalyst bed support

PX Lubricant and Grease Additive Components

The PX series covers additive components for engine, gear, hydraulic, turbine and compressor oils and greases: anti-wear and extreme pressure additives, friction modifiers, antioxidants, dispersants, antifoamants, metal deactivators and rust inhibitors.

PX 3841: non-silicone antifoamant
PX 3239: tolutriazole based metal deactivator
PX 4005: ashless 1000 MW PIBSI dispersant
PX 3806: high-temperature antioxidant

Insoform and Insothane Wire Enamel Materials

Insoform is polyvinyl formal for magnet wire enamels: combined with phenolic resins it gives coatings with high adhesion, thermal stability and mechanical strength, supporting coil life of up to 40 years. Insothane is a blocked poly-isocyanate for solderable wire enamels and varnishes.

Insoform: primary magnet wire enamel coatings
Insoform: magnetic tape binders and adhesives
Insothane CT: solderable polyurethane enamel
Transformer coil life of up to 40 years

Coating Chemicals for Electrical Steel

Coating chemicals for fully processed electrical steel in C-3, C-5 and C-6 classes, engineered for various coating systems and line speeds. The range addresses high line speeds, reduced coating thickness and the transition to eco-friendly materials compliant with European RoHS.

Xylenols and Meta Cresol

Dorf Ketal produces 3,5 Xylenol (3,5 Dimethylphenol, Meta Xylenol) by an in-house catalytic process; the plant was commissioned in 2008. Pharma Grade material is exported to Europe. The range also includes Resin Grade Mixed Xylenol, 2,5 Xylenol and Meta Cresol.

Choosing a Titanate by System and Moisture Sensitivity

Tyzor TPT, TOT and 9000 alkoxy titanates are reactive to moisture and have low to no impact on colour, so they suit silicone RTV-1 sealants, solvent-based acrylics and epoxy adhesives.

Tyzor AA-65, AA-75, AA-105 and IBAY chelates are moisture resistant with a moderate cure rate and moderate colour impact. Tyzor TE is stable in water-based acrylics and polysulfide sealants, and the product guide lists TPT and NBZ with a fast cure for natural rubber.

Cure Profile for Polyurethane and Polyurea

The zirconium-based Unilink 1000 series gives a fast cure profile similar to tin and works with aliphatic and aromatic isocyanates and all polyols; Unilink 1030 suits colour-critical formulations.

The titanium-based Unilink 2000 series gives a slower, delayed cure with a snap final cure similar to mercury, is moisture tolerant and stable in polyols.

Unilink 4100, 4200 and 4230 cure TDI and MDI coating compounds at ambient temperature, and Clearlink 1080 has slower reactivity than Clearlink 1000.

Choosing a PET Polycondensation Catalyst

Compared with antimony catalysts, ACtivate gives higher esterification and polymerization rates, lower diethylene glycol, oligomer and acetaldehyde levels and less haze.

The different crystallinity of the resin shortens mold cycle times for carbonated soft drink bottles and supports light-weighting of hot fill bottles. For polyolefins, titanium alkoxide compounds combined with metal organics serve as Ziegler-Natta catalyst components.

Choosing an Additive Component by Oil Type

PX 3239, a tolutriazole based metal deactivator, is intended for turbine, compressor and hydraulic oils at a dosage of 0.02–0.05 in the manufacturer table. PX 3862, a tolyltriazole and succinic anhydride blend, passivates copper in automotive and industrial gear oils at 0.1–0.5.

The non-silicone antifoamant PX 3841 is dosed at 0.05–0.30 in engine and gear oils, and the PX 3807 antioxidant serves turbine, compressor and aviation oils.
