Welcome to Siltech
Process monitoring using colour change
Thermoprint: A range of inks that change colour when their temperature reaches a “switch” point. They are used as indicators to show Tamper Evidence, or to offer Brand Security, or used as Cooking/Reheating indicators, etc.
Thermosil: These inks are versions of Thermoprint that can be heated by direct thermal printers and hence be a low-cost way to produce thermal labels. An added advantage is that the quality of print will be improved.
Thermoswell: Inks that expand when they are heated. The swell can be high to produce a soft-feel surface, or can be lower in to give the hard finish needed for printed Braille.
Thermocheck: These indicators are used to monitor a baking or annealing heat-treatment.
ThermAlert: Labels made with Thermoprint inks, used to alert to overheating in motors, gearboxes, switches, plugs, pumps, discrete components, etc.
Thermochromic: Inks which fade on heating, but recover their colour when the temperature falls again. They have been used as low-level security features.
Silmark: Silmark is the name of Siltech’s patented, non-contact printing technology. It has numerous advantages over inkjet when used for Marking and Coding. The light beam from a laser is used as the print engine, and accordingly is a high-speed, high-quality, inexpensive, and “green” printing/coding system.
Silkotac: A printable/coatable ink/lacquer designed to impart a soft silky tactility, at the same time being robust. The black version has been compared with velvet.
Thermolak: A water-based Overprint Varnish which is used to protect print (including Thermoprint). It is available clear, opaque or coloured.
Relacsil: An ink/lacquer which prints or coats down to produce a low-energy surface; it is a release lacquer. It is used for tamper-evidence to counter the use of freezer spray as a means to enter a package.
UviBlock: A lacquer which, to the eye, is perfectly transparent. However, in the ultraviolet part of the spectrum, below 370nm, it is opaque, its absorbance approaching 100%. Numerous applications where protection from UV is required.
SilproCheck: Retorting indicators that provide archival proof of treatment.
Sterisure: Inks and label indicators which monitor the Steam, Gamma radiation, Ethylene oxide, and Gas-plasma sterilisation processes.
Suncheck: Monitors (Stickers, Wristbands, Cards, Labels, etc.) to protect the skin against the harmful effects of the UV in sunshine.
