Borica

Borica is a manufacturer of organic titanate and zirconates . Their production facilities are located in China and Taiwan. Borica was started in 1999 and it was a result of a MBO of ICI Taiwan.

The Tytan product line of titanates and zirconates are used in coatings, adhesives, inks and in polymer production.

PRODUCTS BY APPLICATION:

Catalysts: TYTAN manufactured by Borica Co., Ltd. from Taiwan, is the leading range of Organo-Titanate and Organo-Zirconate based catalysts. Borica is committed to providing the chemical industry with a complete range of high performance catalysts delivering to your site through our global logistic network.

Inks: The current range of TYTAN products strongly improves adhesion of printing inks to flexible and metal packaging films while enabling them to withstand heat sealing, freezer storage, abrasive handling, solvents, acids, greases during printing, packaging, storage and handling by consumers. Our range includes TYTANTM AP100, the low odor and low color alternative, fully registered in Europe and the USA.

Industrial Coatings: TYTAN titanates istrongly improve adhesion to metallic substrates through covalent bonding, cross-linking the functional groups of a wide variety of resin binders and acting as coupling agents for pigments and fillers. This allows formulators to develop coatings for a wide variety of binder systems that have the necessary adhesion and anti-corrosive properties to withstand the toughest requirements of today’s general industrial, chemical and transport industries.

For ambient cure coatings heat resistance can be improved to withstand temperatures of 250° C (500° F). For baked coatings the TYTAN products will both engage in additional cross-linking and also have a catalyzing effect on the cross-linking of the resin, resulting in coatings that can resist temperatures of up to 650° C (1200° F).

TYTAN Organo-Titanates are particularly suitable for improving the properties of coatings with silicone based binders, due to the synergistic chemistry of titanates and silicones.

Paint: The CX-range of TYTAN products strongly improves rheological application properties of waterborne paints providing the end-users with non-drip paints with improved flow properties, reduced sagging/spattering and low VOC. In addition to our Organo-Titanate based CX-range, suitable mainly for colloid stabilized paints, BORICA also produces TYTAN ZPN, an Organo-Zirconate based thixotrope suitable mainly for surfactant stabilized paints.

Sealants: TYTAN S-range products allow manufacturers of neutral cure RTV silicone sealants to strongly improve their products to meet the requirements set by today’s challenging construction, automotive, aeronautic and electronic industries.

TYTAN S-range products offer:
• Extended shelf-life through moisture scavenging
• Faster curing through catalysis of hydrolysis of the methoxy terminated curing agents
• Increased modulus of elasticity through crosslinking with Si-OH functional groups
• Improved adhesion to various substrates

Oilfield Chemicals: TYTAN Zirconates/Titanatactes act as cross-linking agents for guar derivatives. They provide hydraulic fracturing fluids with excellent capabilities of propagating the fracture by transmitting hydraulic pressure to the formation and transporting the proppant into the created fracture.

TYTAN TNPZ/TNBZ, main raw materials for a wide variety of specialty organo-zirconate crosslinkers, are included in this range for downstream user’s selection. Compared with borate cross-linkers, the TYTAN range of products offer operational and environmental benefits resulting from:
• Functional at wider pH range
• Environmentally friendly
• Controllable delayed cross-linking rat
• Good thermal stability – workable up to 400°F

Catalysts for Polyurethane: Polyurethane is produced by the polyaddition reaction of polyisocyanate with polyalcohol (polyol) in the presence of catalyst and other additives. Many types of catalysts have been used for polyurethane manufacture, such as compounds of tin, mercury and organic amine compounds. The most commonly used is the tin compound. In many applications, metal catalysts are preferred because they are efficient and effective. For decades, organotin was commonly used as the preferred polyurethane catalyst due to its high activity and good compatibility in most formulations. However, these catalysts, are not favored due to increasing regulatory awareness. This has driven the formulators to search for non-tin alternatives.

TYTAN CA-B116 is a bismuth-based catalyst used for curing a wide range of polyurethane formulations. TYTAN CA-B116 provides much reduced environmental concern and toxicity with higher selectivity and less gassing in the presence of moisture. They are recommended in the area of coatings, adhesives, sealants and elastomers (C.A.S.E.). Furthermore, TYTAN CA-B116 can be used in both one and two component formulations for both ambient cure and heat cure systems.

Coupling & Dispersing Agents: TYTAN Titanate Coupling & Dispersing Agents are molecular bridges at the interface between inorganic fillers (such as CaCO3, BaSO4, graphite, talc, carbon black, silica and metal oxides) and polymers (such as PP, PE, PVC, PBT, PET, ABS and rubbers). When incorporated into polymers, the coupling agent could improve filler loading, pigment dispersion, processability and composite mechanical properties to achieve the specification desired.

As a comparison, silane coupling agents only reacts with hydroxyl groups on the filler surface via water condensation of silanol-siloxane process, therefore it is suitable for glass, alumina hydroxide, magnesium hydroxide etc. The advantage of titanate coupling agents is that they not only react with hydroxyls, but also the free protons on the inorganic interface, which results in the formation of organic monomolecular layers on the inorganic surface forming the bonding for polymers.

Benefits:
• Increase filler dosage from 20% to 30% for cost saving without sacrificing mechanical strength.
• Accommodate recycled polymer through “Repolymerization” of polymers.
• Improve anticorrosion and flame retardation via pyrosphosphate ligand.
• To achieve lighter weight component without sacrificing mechanical properties.
• Reduce viscosity for easy processing.
