Silicone emulsion
WEKO-S1 and WEKO-S1 Protect are silicone emulsion products specially developed for use on high speed water based inkjet printing machines. The application can reliably protect the not fully dried ink on the paper web from smearing, off-setting or even blocking during unwinding of the printed rolls in post press lines. Furthermore, the color abrasion or damage to the printed paper surfaces during post press processes (e.g. cutting, folding, transportation)can be avoided by using WEKO-S1 and SEKO-S1 Protect.

Application
The product must be diluted with water prior to application on the printed paper web. The application concentrations should be in the range of 1% to 10%. The coated paper web could be processed also after more than 24 hours. The product is compatible with stainless steel, chrome, ceramic, PE and PP.
With the WEKO system, you have an absolutely reliable unit that provides precise and consistent liquid application with absolute accuracy. Your process is repeatable and provides you with a stable quality for your daily production flow.
WEKO-S1 or WEKO-S1 Protect applied with WEKO-DigiCon optimizes product quality and improves the efficiency of your continuous digital printing and finishing.
A very uniform and precise fluid application by the WEKO-DigiCon conditions the paper, compensates for paper fluctuations and ensures optimal production. Therefore, not only perfect running and stacking properties are produced, but also dimensional stability for optimal flatness of the paper.
This leads to smooth production processes, less waste and a significant improvement in product quality and further processing.
