KROENERT expands its portfolio with a coating unit for simultaneous double-sided siliconizing
KROENERT introduced the first coating unit for simultaneously siliconizing both sides of a web with solvent-free silicones. Expanding its range of products, KROENERT has redesigned a roll-to-roll system especially for this purpose. This coating unit can be included in new plants or retrofitted in existing facilities. Retrofits offer a special advantage: the flotation dryer already installed in many plants can be used for the non-contact transport of webs and combined with a non-contact air turn in front of the dryer. This feature cuts down on costs for equipment and operations. The process of double-sided siliconizing is especially suitable for paper webs used as release liners for adhesive tapes, for example, and for graphic products.
The simultaneous coating of the front and back of paper webs substantially prevents paper from drying out and the coating machine can be considerably shorter in length, taking up less space. Moreover, the system requires less operators, allowing one person to oversee two coatings at the same time. As only one dryer is needed, this process is resource-efficient and consumes less energy. The siliconizing unit can also be utilized for one-sided coating and operate flexibly with other substrates and silicones.
