Challenges for the Future

This leads us to consider challenges for new high performance pigments, which can be designated as Three Essential Es:

Effectiveness = Technical performance

Economy = Benefits for the customer

Ecology = Environmental and toxicological safety

Better effectiveness could include higher tinting strength, greater ease of disper­sion, better fineness of grind, higher saturation, and so on.

Better economy could include widening the fields of application for known high performance pigments by giving the customer enhanced value-in-use. And better ecology is today’s task for industry as a whole, and is self-evident.

All three “E” will be optimized further on. New inventions will be made, hand — in-hand with steady process and product development. And as we can learn from a study of today’s lowercost pigments, such as lead chromate, where the encapsu­lated specialties of yesteryear are now the norm for coatings application, the high performance pigments of today will become the conventional standards of tomor­row, with those of tomorrow having to be invented now. And so the development of high performance inorganic pigments is, in reality, a never-ending story.
