Tego RC 1904 provides premium release forces in high-speed peel applications like matrix stripping of labels and auto apply label dispensing. Coming as a one-component product, which does not need pre-blending, Tego RC 1904 provides excellent curing performance with high subsequent adhesion values and no loss of tack or adhesion of the label. In addition, it has good anchorage to many different substrates, such as plastic films and papers, without the need to add organic acrylates. Tego RC 1904 ensures premium release forces remain stable over time even under humid storage conditions.
Linerless labels are suited for direct thermal labels, prime labels and wrap-around labels. Direct thermal linerless technology is widely used for print and apply in retail and for hand-held printers in logistic applications. The thermal sensitive paper is siliconized with a UV curing silicone, and the variable information print (VIP) is applied through the silicone layer onto the thermal paper. Existing linerless labels are mainly based on premium top-coated thermal papers. Economic non-top coated thermal papers were not appropriate due to the lack of barrier properties.
Evonik Tego RC 730 offers top face protection for thermal linerless labels against migrating substances. It has been developed for non-top coated thermal papers, but can also be used for top coated thermal paper grades. This enables cost competitive solutions using globally available materials and delivers a far superior direct thermal printing performance.
This is essential for excellent bar code readability and a prerequisite for labeling postal packages. VIP printing and logistic label application are fast and automated processes with the demand for high reliability. Very compact dispensers with enhanced cutting tools are available in the market, meet the technical requirements and offer consistent dispensing processes for linerless labels. Release coatings based on Tego RC 730 do their bit to ensure these constant processes by providing stable release forces over time.
