Customized Binders for innovative Printing Inks

The requirements for printing inks are diverse and vary enormously depending on the field of application. Furthermore, they are influenced by external factors such as high raw material prices and new legislative provisions. In order to meet these requirements, there is a continuous demand for innovative printing inks. Through many years of experience in the field of binder synthesis we are able, in collaboration with our industrial partners, to develop solutions for the challenges which arise.

Possible starting materials for printing ink binding agents include polyurethanes with bio-based polyol components. Our research is, however, also focused upon biogenic oils or biopolymers such as lignin or cellulose. The aim is to thereby achieve the highest possible proportion of renewable raw materials in the binders. The raw materials should thereby be available both inexpensively and in sufficient quantities on the market. A particular challenge is the use of agricultural by-products or the use of biogenic raw materials which do not compete with food production.

The spectrum of applications for our binder developments for printing inks is very broad. We develop innovative, competitive and sustainable alternatives from traditional printing methods through digital printing to 3D printing.
