HeiQ Viroblock – How it works

Though only microns thick, and invisible to the naked eye, our coating powered by the HeiQ Viroblock technology delivers fast, durable protection for the effective lifetime of the printed coating. HeiQ Viroblock’s unique vesicle technology weakens the fatty membrane protecting a virus: taking down its defences. This boosts the effect of our coating’s active silver chloride silver component as it binds and destroys the virus, rendering it harmless in minutes.

So, consumers can handle your printed products with confidence for less than a tenth of a penny per unit.

A world-beating partnership

HiTech Coatings is a division of ICP Industrial Solutions Group, which is the world’s first print coating manufacturer to incorporate HeiQ’s Swiss technology into their products. HeiQ developed the technology to protect frontline medical staff during the Ebola outbreak in 2013. It continued to prove its value throughout the coronavirus pandemic. HeiQ Viroblock has added protection to more than 1 billion face coverings since the beginning of the pandemic. It’s even used in the Royal family’s gloves.

Protection in action

The HeiQ Viroblock technology on our coatings is going to bring a safe to touch surface to children in refugee camps on Europe’s borders, thanks to UK print firm Geoff Neal Group. The coating has been applied to copies of Elephant’s New Friend to be distributed free to 3,000 children in refugee camps throughout Greece. The book—printed in English, Greek and ten mother-tongue languages—is the brainchild of grassroots organisation Play Up Athens. They say: “Before this we had to quarantine books between sessions and wipe them down after each use. This is a game-changer.”
