About Relacsil
We offer lacquers which modify the adherence of adhesives. If adhering films are “peeled-apart”, and a message has been back-printed with Relacsil, then that message remains readable even if the adhesive has been heated or cooled.
Thus, attempts to enter a sealed package by freeze-hardening the adhesive will still result in the visible evidence when peeled apart.
A variant of Relacsil can be radiation-activated to show the same effect, without the need for back-printing. In this way on-demand, variable information can be stored in a covert way until revealed by peeling-apart.

Application
Relacsil is printable and ink receptive release lacquer for pressure sensitive labels, film and tapes. Its high degree of purity and quality offers superior properties and performance to critical users. Relacsil – C131 is designed for use on PE, PP, PET films with various pressure sensitive adhesives, primarily for obtaining release in self wound tapes where tight peel is mandatory. Relacsil is expected to give a peel strength 2-3 times the level expected from most silicone release agents.

About UviBlock
This is a polymer lacquer, which to the eye, is perfectly transparent at wavelengths above 400nm. However, at lower wavelengths, e.g. below 370nm in the UV region, the lacquer absorbs strongly and it's absorbance approaches 100%.
This technology lends itself to numerous applications: the lacquer could be coated onto PET bottles to protect beverages, or onto film to protect food stuffs. It could be the basis of transparent shop-window blinds that protect textiles and other goods from deterioration in the UV from sunshine or it could be incorporated into an overprint varnish to give outdoor posters a longer life.

Application
UV Absorbing Lacquer EPT330 can be applied by the Gravure or by the Flexographic printing process with little danger to polymer plates. It exhibits good adhesion to polyolefin films as well as to PET and PVC. It is recommended that polypropylene be corona discharge treated before printing. If required, the appropriate thinners or retarders can be added to modify the drying/printing characteristics on press.
