Technology Overview

Antimicrobial coating is an effective way to slow down the spread of pathogens on surfaces by inactivating bacteria, viruses and fungi when they contaminate a surface. Despite being commercially available, the cost and durability of the anti-microbial coating technology can still be further improved. Common commercial coatings that are available to consumers have a gradually diminishing antimicrobial strength and mostly only last for a few months. Other longer lifetime coatings exist for industrial coating producers but are produced with exotic and expensive processes.

A cost-effective process has been developed to fabricate antimicrobial coating. The coating is tested to be durable with high antimicrobial efficacy.

Technology Features

• A metal oxide-based nanowire layer coating obtained by Chemical Bath Deposition

• The coating is tested* to be more mechanically durable than commercially available coating

• Multi-functional coating with antimicrobial, antireflective and photocatalytic properties

• Effective even without UV light

• Proven to work using ISO22196 test with >99% efficacy

Potential Applications

• High touch surfaces i.e touch display panels etc.

• Self-cleaning coating for building facades

• PV System

• Air / water purifying coating

Benefits

• Antimicrobial with good efficacy

• High transparency – suitable for glass surfaces and screens

• Durable

• Self-cleaning – reduces the amount of labour and chemicals for disinfection

• Cost-effective
