Within a matter of weeks, normal day-to-day life changed to something more akin to a horror film as many nations introduced draconian measures in order to reduce the spread of the virus and prevent the numbers of patients requiring hospital treatment overwhelming their intensive care facilities. In light of the perceived high infectivity of the virus, members of the Royal Society of Chemistry's Surface Coatings Special Interest Group, in collaboration with the British Coatings Federation, organised a virtual gathering of more than 130 academics, industry specialists and representatives of healthcare and transport organisations to share knowledge about antiviral coatings and express views on what needs to be done to accelerate research output in this field. One of the aims of the meeting was to review hygienic coatings technology' and its prospects for fighting viruses.

Novel oil-modified acrylic multi-domain dispersions for wood coatings in SURFACE COATINGS INTERNATIONAL, Vol. 103.3 (05-06/2020)  

[article]  inSURFACE COATINGS INTERNATIONAL > Vol. 103.3 (05-06/2020) . - p. 128-131 Titre : Novel oil-modified acrylic multi-domain dispersions for wood coatings Type de document : texte imprimé Année de publication : 2020 Article en page(s) : p. 128-131 Langues : Anglais (eng) Catégories : Bois -- Revêtements protecteurs Essais (technologie) Essais d'adhésion Formulation (Génie chimique) Polyacryliques Résistance aux conditions climatiques Résistance chimique Revêtements -- Finition Revêtements en phase aqueuse:Peinture en phase aqueuse Revêtements organiques Index. décimale : 667.9 Revêtements et enduits Résumé : Waterborne acrylic dispersions and alkyd emulsions have been extensively used for architectural coatings for decades, each technology having its advantages and drawbacks. While alkyd emulsions generally exhibit very good application characteristics, such as high gloss and good penetration, they lack in performance for weathering resistance. Acrylic dispersions, conversely, are disadvantaged in terms of flow, levelling and appearance, but perform well for outdoor durability. Many attempts have been undertaken to find the balance of performance by hybrid technology approaches. The presented work highlights a novel synthetic approach to oil¬modified acrylic multi-domain dispersions combining acrylic-like outdoor durability with alkyd-like appearance and application properties.
