A coating is a substance applied to a material or a product to enhance the material/product overall properties, such as water wettability, solvent resistance, gas or solvent permeability adhesion, and/or resistance to wear without affecting bulk properties. It can be decorative, protective and – in the case of smart materials – add functionality to the product, i.e. switch properties under external control.
How are coatings used?
Coatings have a broad range of uses, including:
To change the touch/feel of a material
To change gas and solvent permeability of material e.g. to protect gas/moisture sensitive materials
To improve adhesive bonding
To improve wettability and printability of water hating materials
To make ‘splash proof’ or waterproof
To prevent staining of materials
To make self-cleaning
To improve biocompatibility (implants/ex vivo devices)
To impart anti-microbial and anti-viral touch- properties
Functional coatings represent a multi-billion pound industry within the UK and are applied to products as diverse as contact lenses and drinks cartons; they are found in automotive products, textiles, polymer/plastic films, construction materials, and products and processes affected by biofilms, e.g. pipes and medical implants
