that the global plastics industry also faces increas- ingly stringent regulations in sensitive applications such as food contact materials and toys. Accord- ingly, Colors & Effects has been extending its Utmost Purity pigment range, which it launched last year with the introduction of Irgazin Red K 3840 UP. This has now been joined by Heliogen Blue K 7097 UP. Dumont says the pigments are intended to allow users to keep ahead of regulatory changes and are supported by food contact certificates. For consumer goods, where bright colours and sparkling effects are often an important selling factor, Colors & Effects has launched Irgazin Rubine K 4082, which Dumont says is an improved Rubine DPP pigment. “Its extreme transparency turns it into an excellent formulation partner for brilliant effect pigments like Lumina Royal Russet to achieve vivid lava reds with strong sparkling effects,” he says. High chemical purity also enables the new pig- ments to meet global regulations for food contact.

Expanding capacity Canada’s DCL Corporation — the result of the 2018 merger of Dominion Colour Corp and Lansco Colors — has been building new high performance pigment capacity that was commissioned a few weeks ago. “We believe this may be the first investment in new capacity of its kind in North America for decades,” says Frank P Lavieri, Execu- tive Vice President Sales & Marketing at the company. “We intend to manufacture Hansa and benzimidazolone yellows primarily for the coatings industry, and calcium salt azo yellows (Yellow 62, 168, 183, 191) and Yellow 155 primarily for the plastics industry. We feel that this new capacity will meet a need for high quality pigments available with short lead times.” Meanwhile, Lanxess has added to its technical services for pigment customers. Its IPG business
unit now has an expanded technical centre in operation at its largest site in Krefeld-Uerdingen, Germany. The facility is equipped to carry out automated measurement of thermal stability in customer-specific plastics applications. “From sample-loading to colorimetric analysis, all the necessary modules can be actuated via automated processes,” says Bartolucci. “That allows us to carry out highly specific tests with supreme accuracy.” Lanxess now also offers extensive pigment
expertise for colouring filaments for 3D print applications. At the Uerdingen centre it can carry out in-depth tests on the effects of pigments, and advise customers on colouring with iron-oxide pigments. “For example, in the case of short dwell times and relatively low shear forces in the process- ing machines, it is necessary to ensure good dispersibility,” says Bartolucci. “The pigments need to be easy to distribute and
must reach their final colour strength quickly,” he says. “At the same time, we can demonstrate ways of partially reducing the organic pigment content in a filament formulation by means of iron oxides, when the application calls for better weather stability.” Bartolucci also says that, in contrast to organic colorants, inorganic pigments provide high temperature and weather stability at relatively low costs, as well as excellent migration resistance.
