| Printing Inks-Water based flexo |
 |
Solvay precipitated calcium carbonates can be used in water based inks for flexographic printing applications. The small particle size, absence of abrasive impurities, high chemical purity and rheological contribution make these products a useful addition for formulating water based flexo inks. When dispersed, these products can exhibit excellent transparency that allows their use to produce extender varnishes that can be used to manipulate colour strength without adverse effect on rheology or colour shade. Other surface ink properties are improved and anti-blocking, anti-slip,surface hold out and ink lay-down all benefit from the inclusion of precipitated calcium carbonate.
Coated ultrafine grades of SOCALŪ and WINNOFILŪ provide improvements in stability,transparency and surface smoothness without adverse effect on gloss.
Starting point formulations are available on request.
