Eckart has expanded its successful portfolio for gravure and flexo printing as well as shrink sleeve applications with a series of new silver pastes. Rotovario 501 811, 530 107, 532 501 and 532 504 are based on ‘silverdollar’ pigments. They enrich the portfolio with new shades.
What is more, they impress with a number of further advantages. Rotovario 501 81, for example, combines high gloss silver effects with an excellent hiding power.
The whitish metallic effect of Rotovario 530 107 remains largely unchanged over the entire viewing angle. The paste creates a uniform structureless metallic optic. It is suited to carton, board, and flexible applications. Owing to its good hiding power, the pigment concentration of formulations with 530 107 can be reduced by up to 30%, without compromising hiding power.
On the other hand, 532 501 and 532 504 convince with their excellent overprintability. Alternatively, the two silver pastes can be combined with colour inks or toner to achieve interesting, polychromatic effects. They are particularly suited for bright effects on film or board applications. In contrast to the other pastes which are stabilised in ethyl acetate solutions, n-propyl-acetate is being used to stabilise the Rotovario 532-pastes. This guarantees their exceptionally long shelf life of 24 months.
Also new are Rotovario 501 023 and Rotovario 501 033, which offer intense, structureless metallic effects, silky surfaces, and good hiding power.
These two pastes are based on extremely small Cornflake pigments. With their excellent ink transfer the pastes are specially designed for applications characterised by fine lettering, detailed design, and smooth surfaces.
The fascinating product innovation is the result of the Eckart’s elaborate lab know how. It succeeded in stabilising the fine pigments with special additives in ethyl acetate (with 6 µm and 9 µm their particle size lies below the traditional particle size of 10 µm). Accordingly, the pigment pastes are suited to solvent based solutions in gravure and flexo printing. Thanks to their excellent printing results they can also be processed at high speeds, for example in label printing, flexible packaging, or shrink sleeve applications.
Rotovario 501 023 offers a rather dark metallic effect, while 501 033 impresses with its bright appearance.
