Additives and binders for flexo, gravure and offset printing and for overprint varnishes.
Printing inks run at high press speeds in the thinnest of films — pigment concentrates must be colour-strong and storage-stable, waterborne flexo inks must run foam-free through the anilox unit, and the finished print should withstand rubbing, stacking and converting. Every nuance in wetting and rheology shows in the printed image.
From BYK we carry wetting and dispersing agents for pigment concentrates, defoamers for waterborne systems and wax additives for rub resistance and slip; dispersions from Alberdingk Boley complete the binder side of waterborne inks and overprint varnishes.
