Index. décimale : 667.9 Revêtements et enduits Résumé : The labelling regulation changes which will take place this year, for the biocides market, as well as products designed to minimise the effects of these changes. It is abundantly clear that 2015 will be a time of great change for customers and raw material suppliers in the highly regulated European market. The ramifications of all these changes will have a major impact for customers and suppliers who wish to market and sell their products within the European Union. For those customers who want to be warning phrase-free under the CLP legislation the choice of actives will be severely limited coupled with an increased cost to treat. Additionally, only those suppliers who are listed on the ECHA list of approved substances, will be able to supply, whilst remembering that this list also limits active ingredients to product types as defined in the BPR. This will mean no more traders and 'free-riders : Therefore, only prime manufacturers, which have invested in and have fully supported their active ingredients through the BPR and fully understand the legislation, will be the ideal partners with whom to build and discuss your future preservation requirements.

Breaking the mould / John Gillatt in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 193, N° 4469 (10/2003)

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 193, N° 4469 (10/2003) . - p. 21-25 Titre : Breaking the mould Type de document : texte imprimé Auteurs : John Gillatt, Auteur Année de publication : 2003 Article en page(s) : p. 21-25 Langues : Anglais (eng) Catégories : Algicides Antifongiques Antimicrobiens Revêtements en bâtiment -- Détérioration:Peinture en bâtiment -- Détérioration Revêtements en bâtiment:Peinture en bâtiment Index. décimale : 667.9 Revêtements et enduits Résumé : Changing labelling regulations require new ideas and the introduction of new blends of biocides. The author explores the strategies for decontamination. Of the three main groups of microorganims that can infect paints, plasters and similar surface coatings it is fungi and algae that are especially problematic after the material has been applied. Fungi cause surface disfigurement and actual degradation, while algae also detract from the product's aesthetic qualities as well as retaining high levels of moisture with resultant damaging effects. Exterior surfaces can become infected with both types of organisms and broad-spectrum antifungal or antialgal biocides have been developed to prevent such growths. However, changing legislation relating to the labelling of such biocides, pressure from environmental and consumer groups and revised regulations concerning insulation of buildings, have placed greater and greater demands on biocides and have created a need for new products with novel properties.

Meeting all the challenges / Emmanuelle Yvon in EUROPEAN COATINGS JOURNAL (ECJ), N° 4 (04/2015)  

[article]  inEUROPEAN COATINGS JOURNAL (ECJ) > N° 4 (04/2015) . - p. 132-136 Titre : Meeting all the challenges : European regulatory framework for biocides will become stricter in 2015 Type de document : texte imprimé Auteurs : Emmanuelle Yvon, Auteur ; Paul Wood, Auteur Année de publication : 2015 Article en page(s) : p. 132-136 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Algicides Antimicrobiens Bioaccumulation Chimie industrielle -- Aspect de l'environnement Chimie industrielle -- Législation -- Pays de l'Union européenne Produits chimiques -- Etiquetage Substances dangereuses -- Législation -- Pays de l'Union Européenne Index. décimale : 667.9 Revêtements et enduits Résumé : Restrictions imposed by the EU's Biocidal Products Regulation will increase during 2015. The presence of skin-sensitising substances above a threshold level now triggers labelling with a warning phrase. The Water Framework Directive is likely to restrict the use of some established algaecides because of their bio-accumulation potential. Alternative active materials are suggested.

Natural compounds as potential algaecides for waterborne paints / Sandra G. Gomez de Saravia in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 15, N° 5 (09/2018)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 15, N° 5 (09/2018) . - p. 1191-1200 Titre : Natural compounds as potential algaecides for waterborne paints Type de document : texte imprimé Auteurs : Sandra G. Gomez de Saravia, Auteur ; Silvia E. Rastelli, Auteur ; Guillermo Blustein ; Marisa R. Viera Année de publication : 2018 Article en page(s) : p. 1191-1200 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Algicides Antimicrobiens Biomolécules Composés organiques Revêtements en phase aqueuse -- Additifs:Peinture en phase aqueuse -- Additifs Index. décimale : 667.9 Revêtements et enduits Résumé : To eliminate and prevent the formation of phototrophic biofilms on painted walls, chemicals are added to paints. These chemicals, in general, also have toxic effects on the environment. Plants synthesize secondary metabolites which have antimicrobial properties and that may be a sustainable alternative to traditional biocides. In this work, algal species isolated from biofilms formed on deteriorated painted surfaces were taxonomically identified. Observations with the optical microscope revealed the presence of mixed biofilms composed of algae belonging to the Cyanophyta, Chlorophyta, and Streptophyta divisions. The algaecide effect of natural compounds of vegetal origin such as anisole, eugenol, guaiacol, and thymol was evaluated by the microatmosphere technique. Growth inhibition of phototrophic organisms was obtained with thymol in all the concentrations used. Eugenol and guaiacol showed a total growth inhibition at the highest concentration assayed (300 μmol cm−2) and a decrease in growth at 40 μmol cm−2, while anisole did not exert any inhibitory action at the assayed concentrations. Due to these results, eugenol, thymol, and guaiacol were incorporated in an exterior waterborne paint at a concentration of 2%. Samples painted with these formulations were not colonized by algae, indicating that these compounds could be used as biocides in paint formulations.

Seeking alternatives / José Mosquera in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 197, N° 4508 (01/2007)  

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 197, N° 4508 (01/2007) . - p. 36-37 Titre : Seeking alternatives Type de document : texte imprimé Auteurs : José Mosquera, Auteur Année de publication : 2007 Article en page(s) : p. 36-37 Langues : Anglais (eng) Catégories : Algicides Antifongiques Antimicrobiens Chimie industrielle -- Législation -- Pays de l'Union européenne Etiquetage écologique Produits chimiques -- Etiquetage Revêtements (produits chimiques):Peinture (produits chimiques) Index. décimale : 667.9 Revêtements et enduits Résumé : This paper sets out solutions to confront the new European Environmental Labelling. The publication in January 2006 of the 2nd Amendment of the Dangerous Preparations Directive establishes more stringent labelling requirements of preparations (ie paints and coatings) containing chemical substances classified as being toxic for the environment. European Member States are required to make this Directive effective in their National laws by March 1, 2007. The consequence is that many paints containing specific algicides will have to carry the environmental N-symbol and corresponding Risk phrases. There are, however, alternative biocides, which will not trigger the environmental label and provide excellent fungicidal and algicidal efficacy. Note de contenu : - Environmental classification and labelling - Substances used in coatings that will trigger the label - How does this affect the choices for the coatings formulator ? - How to achieve the same or better algicidal and fungicidal performance without the N-symbol ?
