Bio-based additive enhances design possibilities

At the European Coatings Show (ECS) in Nürnberg, Germany, specialty chemical company Clariant will introduce a natural based alternative for safer, hard-working printing inks for food applications, and publications on enhancing the long-term natural appeal and design possibilities of glass.

According to the manufacturer, a predominantly-bio-based micronized wax makes sure that all kinds of food packaging and publication inks will not rub off. Ceridust 8330 is said to be predominantly based on a renewable ingredient. It reportedly outperforms conventional waxes by providing inks with rub resistance properties without the need for PTFE (polytetrafluoroethylene).

Furthermore, the amount of wax reportedly can be reduced by 30-50% without any reduction to the high level of rub resistance. It adds up to less additive and greater efficiency without compromising on performance.

More glossy and metallic

Another new additive is the Hostatint A-100 ST highly-transparent pigment preparation. By using them, packaging providers are said to be developing bottles and containers featuring creative effects, bringing out the brillance of glass and the color intensity of novel metallic and pearlescent mineral effects. Unlike dyes, the high weather and light fastness reportedly means long-term appeal and no migration or bleeding. The pigment preparations also have a long shelf-life and are easy and safe to use, according to the company.

The beverage industry is also seeing the advantage, using the high-transparency to introduce eye-catching gold and bronze colored can lids on cans. The value of pigments extend to other consumer areas too, for example, through metallic effects for decorative glass, smartphones, and helmets.
