Prof. Li Pei of PolyU’s Department of Applied Biology and Chemical Technology and Mr. Tenny Lam, a PolyU Doctor of Business Administration candidate, introduced their prize-winning product CareCoatex antimicrobial coating.
The co-founders of the PolyU-nurtured startup, Grand Rise Technology, said the non-toxic and eco-friendly antimicrobial spray coating was made of food-grade chitosan from crustacean shells and encapsulated thymol from the culinary herb thyme, combined with Prof. Li’s core-shell particle technology.
The coating offers not only contact killing, but also time-release action for as long as six months. Besides high-touch surfaces like doorknobs, elevator buttons, and medical devices, it can be sprayed on fabric and clothing items, or even used in antiseptic wipes. The product could also be applied to industrial use like air purification.
Apart from the local market, the coating has entered Asian markets like mainland China, Singapore and Malaysia. The company is also working on other products like the FruitCoatex which helps fruit last longer.
