Stable pigments that can withstand multiple recycling steps are also important. Both voluntary measures and regulations,

strength and improved dispersion and generate a masterbatch with higher pigment loading, which would mean that their downstream customer could use less masterbatch to achieve the desired end shade,” Howie says. Dominion Colour is also currently expanding its manufacturing footprint in Canada, adding 1000 tonnes/yr of medium to high-performance organic pigment capacity. The expansion is expected to come online by the end of the third quarter.

particularly in the EU, are driving rapid improve- ments of waste collection rates and subsequent recycling, says BASF’s Dumont. In addition, brand owners intend to increase the use of recycled materials in packaging articles. “In this context the replacement of carbon black to better enable sorting and recycling of black coloured waste is gaining momentum, especially for the packaging industry,” he says. BASF will introduce two pigments at K2019 that


are designed for recyclability. Sicopal Black K 0095 is NIR-reflective and allows reliable detection even at high pigment concentrations. It has been tested in sorting equipment with polymers such as PET and PP. Sicopal Red K 3050 FK is a new pigment chemistry that extends the durable red colour space with NIR-reflectivity that allows NIR-sorting. It can also be used in heat-management applications. The
