Laser Reactive Inks & Lacquers

Silmark is the name of a system whereby the light beam from a laser is used as the engine for a rapid, clean, non contact printing system. Inks are made to respond to the output from CO2 (10,000nm) laser or from a Nd/YAG (1064nm) laser.

Thermally Sensitive Inks & Labels

Heat reactive inks are available in a number of colours that give a permanent colour change on heating. They are optimised for each particular application: tamper evidence, direct thermal labels, cooking/annealing indicators, temperature indicators, brand protection etc.

Speciality Inks & Lacquers

Lacquers for total block of UV (but complete passage of visible light), lacquers with low surface energy and lacquers with special surface effects.

UV Colouring Inks & Labels

Monitors to protect the skin from overdose of UV from the Sun are available in several formats: stickers, cards, wristbands etc. They may also be used for UV sterilisation indicators, curing indicators etc.

Security Print Systems

Many of Siltech's products are unique in performance and secure in availability, for example thermal systems, UV, and IR systems. In addition we offer systems based on luminescence, surface effects, etc.

Sterilisation Inks & Monitors

Sterisure is a range of indicators which show when a sterilisation process has taken place – available for steam, gamma radiation, plasma H2O2 and ethylene oxide – sterisure makes a distinct, obvious colour change when the dosage has been reached

About Siltech

Siltech Limited is a company that has developed a unique expertise in smart ink technology. Our inks change colour, volume, opacity etc. when exposed to heat, UV, radiation, steam or other stimulants and can be used as sophisticated indicators and monitors of change, or as new and innovative printing or marking technologies.

Siltech Limited is a privately owned company that develops and manufactures smart inks, lacquers and labels for sale into the printing, packaging, security (brand protection, traceability, tamper-evidence), medical sterilisation, heat and radiation curing, food retorting, coding & marking, etc, sectors. Siltech has developed an extensive portfolio of intellectual property as well a range of almost 20 products that have been released to market since 2010.

From our laboratories in Nottingham, we specialise in developing chemical systems which can be stimulated with energy to produce a change in colour, opacity, volume or surface texture. We have products which respond to the following sources of stimulation: Laser, LED, Steam, Heat, Gamma radiation, UV/ IR radiation, Ethylene

oxide, etc.
