Respirator masks with or without HeiQ Viroblock. Our offer in the global Covid-19 pandemic Zurich, 11 May 2020

Purpose HeiQ �� gl�bal ne����k HeiQ is a textile innovator with offices in 6 countries and a global network of textile manufacturing and distribution. In view of the global coronavirus pandemic and the severe shortage of medical personal protective equipment (PPE) in many countries, we are mobilizing our global team and network to help source these essentials to help hospitals, first responders, essential services, governments and businesses. As the current pandemic is disrupting our textile industry we see it as our primary duty to contribute to swiftly returning to a status quo ante and put all our resources to help fight the global pandemic. This is not our core business, but we are trying our best to leverage one of our core competencies: a small yet global and flexible company. As a small company we must set a price so that we cover the cost to acquire these items as well as HeiQ offices & productions high logistics costs in such times. The surplus, if any, would be used to compensate our team who HeiQ brandforce dedicate their time to help with this initiative and secure jobs at such time of uncertainty.

TESTED EFFECTIVE AGAINST CORONAVIRUS HeiQ has launched HeiQ Viroblock NPJ03, an antiviral and antibacterial textile treatment � a unique combination of silver and vesicle technologies designed to significantly reduce viral and bacterial infectivity on treated surfaces. 3

HeiQ Viroblock NPJ03 � antiviral textile technology � Effective protection against contamination and Technical USPs transmission of viruses and bacteria that use textiles as a hosting surface � Non-dangerous good: logistics � Kills bacteria and destroys viruses in minutes and storage convenient � Can be applied to all types of � Effective against common harmful viruses such as fabrics and nonwovens influenza and coronavirus � Standard continuous wet- Breakthrough combination of two leading HeiQ � processing applications technologies: (padding, kiss-roll etc.) � Application 5% to 20% w.o.f. � H��Q�� registered silver technologies for antiviral and antibacterial effect H��Q�� fatty vesicle technology as a booster that � destroys viruses � Harnesses the natural antiviral and antibacterial properties of silver Oekotex, Bluesign, ZDHC: pending for approval 4

HeiQ Viroblock � Silver component � Small silver particles are potent antibacterial and antiviral agents due to high surface area to volume ratio and unique chemical and physical properties 5) � Small silver particles are effective against viruses, effectively eliminating them following short exposure of isolated viruses to silver 5) � Silver attracts the oppositely charged viruses and binds permanently to their sulfur groups � HeiQ small silver particles contribute to a broad- spectrum of antiviral mechanisms that are not prone to inducing resistance A) Transmission electron micrograph showing an amorphous silicon dioxide aggregate particle (gray structure) together with numerous supported silver metal particles (dark spots). (B) Scanning transmission electron micrograph of the structure shown in panel A, providing better contrast between the silica structure (gray) and the silver metal particles (bright spots). (C) Higher magnification of the region in panel B enclosed in a box. The silver metal particles are typically between 1 and 10 nm in 6) diameter. 5) Stefania Galdiero ��. a�.
