| Résumé : |
Stain resistant and easy to clean coatings is in great demand and the focus of a lot of research activity globally. Additives based on fluoro (oleophobic) and silicone (hydrophobic) chemistry have been developed that provide easy to clean coatings. Being surface active they lower the surface energy of the coating thereby making the coating either difficult to stain in the first place or easy to clean. Such additives also have other benefits such as protecting the coating from micro-organisms, leading to improved sanitation and cleanliness, improved water and chemical resistance; anti-graffiti properties and giving the coating a new look for a longer time. Such addtives have found their source of inspiration from nature (biomimetic); particularly the lotus leaf which shows excellent hydrophobicity (a very high contact angle). This paper focuses on the chemistry of easy clean additives, how they work, and their use in coatings; highlight the need for a permanent effect, their advantages and current research in the field. |
