Polymeric Resin Additive Paste for High Wettability and Photocatalytic Effect

Technology Overview

High wettability and photocatalytic effect are crucial elements for achieving self-cleaning surfaces. Self-cleaning surfaces minimise the need for labour intensive and costly cleaning and maintenance services.

However, commercially available self-cleaning solutions are typically in the form of coatings that wear off with time and require re-application, which is costly and time consuming. In view of the limitation of current commercially available self-cleaning coatings, a polymeric resin additive paste that enables long-term high wettability and photocatalytic effect has been developed.

Technology Features & Specifications

The developed polymer resin additive paste can be incorporated into the raw materials at the manufacturing stage to enable high wettability and photocatalytic effect. The photocatalytic capability enables the breaking down of organic particles while the high wettability facilitates washing off of the broken down particles by the formation of water films.

The paste has been tested according to ISO 16474-2 to show sustained high wettability and photocatalytic effect for at least 5 years. The additive paste is currently based on polyester and may be customisable to different polymeric materials, e.g. epoxy, polyurethane etc.

Potential Applications

The polymer resin additive paste may be adapted into the raw materials used in the manufacturing phase to achieve long-term high wettability and photocatalytic effect in the product.

These products may potentially include anti-bacterial surfaces, water purification systems, anti-fouling surfaces, composite structures and architectural products that require long term and sustainable self-cleaning functions.

Customer Benefits

Product developers and manufacturers looking to incorporate long-term self-cleaning capabilities into their products may benefit from the use of this new technology developed.
