F O C U S suitable for use in dispersions, artist colours, clay targets, wax colorants and water-based paints. The 310 and 311 series are improved versions of the current IxT series, offering better thermal and solvent resistance properties. Pigments in the 910 series, designed for PVC calendering and EVA coloration, have very fine and uniform particles with narrow particle size distributions. Pigments in this series have excellent nonmigrating and non-bleeding properties. They are suitable for particularly demanding applications such as plastisol inks, aerosol paints and liquid inks.

Heubach seeks licensees for new synrutile manufacturing process The Heubach group has announced the development of a new technology for making synrutile, described as Reptile-96. It is now actively looking to license its technology to any potentially interested party in the world TiO2 pigment and feedstock sectors. Dr Emmanuel Tesone (based at Fairless Hills in the US) is the project leader, while Dr Reinhard Marx will cater for enquiries from Europe, Asia and other parts of the world. The term “reptile” is taken from “replacement rutile” and the synrutile product yielded typically contains 96% TiO2. The company states that the process is unique and cost-effective because of its optimised chlorination and dechlorination technologies. The process represents a refinement of technology originally pioneered by Dr Wendell Dunn (formerly with DuPont). It entails fluid-bed drying of ilmenite feedstock, followed by direct chlorination at over 1000˚C in the presence of calcined petroleum coke. The iron units in the ilmenite are converted to ferric chloride and then to ferric oxide – following the introduction of oxygen at the chlorine recovery stage. Heubach has built a demonstration unit at one of its India pigment complexes, which is operated to produce 100 kilos of synrutile per batch-cycle. To build a commercialscale plant, operating in India and producing 16,000 tonnes/y of

synrutile, the initial capital investment requirement would be about $8 M. First estimates for operating costs, based on data derived from the demonstration unit, are of the order of less than $0.10/kg of synrutile – including the costs of energy, makeup chlorine, operative labour, maintenance and other direct costs, but excluding the costs of ilmenite and capital.

Jameson’s colour-glow plastic pigments Jameson Technologies has introduced DualGlo plastic masterbatches and compounds. These are said to be 30% more effective than conventional materials. Bright daylight colours can be achieved with good afterglow output and longevity. DualGlo is available in a range of forms – compound, powder, or as a universal masterbatch. In addition to standard red, yellow, green, blue and orange colours, it is also available in brilliant white. SpecialChem, 18 Feb 2002, 1 (Website: http://www.specialchem.com)
Millennium’s new TiO2 pigment Millennium has introduced Tiona 696, a TiO2 pigment grade designed for use in industrial paints and plastics. It incorporates the high durability of silica-encapsulated products and the improved optical properties of zirconia-stabilised products. In industrial coatings, Tiona 696 will be useful for coil and powder coatings, automotive refinishes, organisols and plastisols. Applications in the plastics sector include: polyvinyl chloride (PVC) window and door profiles, fencing and decking; agricultural plastic film; and tanks, pipes and furniture in both PVC and polyethylene.

Milliken’s liquid colorants for PET Milliken Chemical has launched the ClearTint line of liquid colorants and the ClearShield ultra-violet absorber
for incorporation into polyethylene terephthalate (PET) compounds. The colorants, supplied as non-settling liquids, are said to be easy to mix and are available in a wide range of colours. They will be mainly used for clear PET bottles and other packaging containers. Milliken has already begun manufacturing ClearTint colorants at its Ghent plant in Belgium. For the polyurethane sector, Milliken offers its Reactint series of colorants. These are designed for applications in rigid and flexible polyurethane foam, reaction injection moulding (RIM) compounds, cast elastomers and adhesives.

Nubiola’s new ultramarine & zinc ferrite pigments Nubiola (of Barcelona) has launched two new pigments. Nubicoat is an ultramarine blue pigment, the production of which involves an innovative coating process designed to enhance resistance against acids and abrasion. Nubicoat is easily dispersible and generates a tinting strength equivalent to most noncoated ultramarine pigments. Nubiterm is a zinc ferrite pigment, with good thermal stability up to at least 300°C and good chemical resistance, as well as being lightfast. It is available in a variety of shades. Besides ultramarine and zinc ferrite pigments, Nubiola’s pigment portfolio also includes chrome oxide green, lead chromates, molybdates and iron oxide pigments.

Schulman’s masterbatches for agricultural film Schulman has launched two new masterbatches specially designed for incorporation into agricultural plastic film. The new products – Polybatch Silver 70100U and 70400U – offer better reflective properties and are said to be ideal for combating weed growth, promoting plant growth and controlling pests.
