Cobalt driers - Are there any real alternatives ? / Hugh Gibbs in DOUBLE LIAISON, N° 550 (05/2006)

[article]  inDOUBLE LIAISON > N° 550 (05/2006) . - p. 36-40 Titre : Cobalt driers - Are there any real alternatives ? Type de document : texte imprimé Auteurs : Hugh Gibbs, Auteur Année de publication : 2006 Article en page(s) : p. 36-40 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Cobalt Liants Réticulation (polymérisation) Revêtements Index. décimale : 667.9 Revêtements et enduits Résumé : The recent classification of some water soluble cobalt salts as category 2 carcinogens within the EU has prompted much speculation that cobalt carboxylates (such as cobalt 2―ethylhexanoate) traditionally used as the primary drier in alkyd coatings may ultimately be classified in the same way which would effectively end their use in decorative paint formulations. New data on an alternative class of cobalt driers ― cobalt boroacylates will be presented showing these compounds have significantly reduced water solubility compared to the traditional cobalt driers and it will be explained how this reduced solubility makes these compounds an excellent alternative to the traditional driers.

Regulatory compliant dry-film biocides - Future-proof products ? / John Gillatt in DOUBLE LIAISON, N° 550 (05/2006)

[article]  inDOUBLE LIAISON > N° 550 (05/2006) . - p. 41-48 Titre : Regulatory compliant dry-film biocides - Future-proof products ? Type de document : texte imprimé Auteurs : John Gillatt, Auteur Année de publication : 2006 Article en page(s) : p. 41-48 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Liants Revêtements Revêtements antisalissures:Peinture antisalissures Index. décimale : 667.9 Revêtements et enduits Résumé : Fungal and algal growth on both interior and exterior coatings has been recognised as a serious problem for many years and biocidal additives have been developed to deal with such growths. However, when such products are considered in detail it will be seen that only a small number of active agents are used in such formulations. These are now under pressure as a result of changed industry needs, environmental and consumer demands and the activities of regulatory authorities, especially those in Europe. As a result, particularly of the implementation of the Biocidal Products Directive (BPD) and the Adaptations to Technical Progress (ATP) of the Dangerous Substances Directive (DSD), active agents used in the past are now being either discontinued or much more strongly restricted, creating a need for new products will novel properties. Although such demands represent a significant challenge to the biocide manufacturer it has been possible to meet these requirements.
