Stabilizers / Vladimir V. Verkholantsev in EUROPEAN COATINGS JOURNAL (ECJ), N° 3/00 (03/2000)
[article]
Titre : Stabilizers Titre original : Coating additives, part XIII Type de document : texte imprimé Auteurs : Vladimir V. Verkholantsev, Auteur Année de publication : 2000 Article en page(s) : p. 58-63 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Coating material' Paint Adjuvant 'Stabilizer agent' 'Light stabiliser' Antioxidant 'Heat stabilizer' Index. décimale : 667.9 Revêtements et enduits Résumé : Stabilizing additives protect organic coatings against various forms of degradation and destruction of service properties under the action of sunlight, atmosphere oxygen, moisture, elevated and alternated temperatures, microorganisms and other service conditions. In the narrow sense, UV-absorbers, UV-stabilizers and anti-oxidants, preventing light, oxygen and heat degradation of binder resins, are described as stabilizing additives. In a broader sense, however, a number of other groups of coating additives are in fact coating stabilizers, such as bio-preservatives, corrosion inhibitors, adhesion promoters, some surface conditioners etc. Note de contenu : - Coating stabilization

[article]
Titre : Urea fertilizer coated with biodegradable polymers and diatomite for slow release and water retention Type de document : texte imprimé Auteurs : Jean Felix Mukerabigwi, Auteur ; Qing Wang, Auteur ; Xiaoya Ma, Auteur ; Min Liu, Auteur ; Shaojun Lei, Auteur ; Haitao Wei, Auteur ; Xueying Huang, Auteur ; Yu Cao, Auteur Année de publication : 2015 Article en page(s) : p. 1085-1094 Note générale : Bibliogr. Langues : Américain (ame) Tags : 'Water retention' 'Slow release fertilizer' 'Coating material' Diatomite Biopolymer Urea Index. décimale : 667.9 Revêtements et enduits Résumé : Slow release fertilizers (SRFs) are of vital importance to improve agricultural efficiency. However, their use is still limited due to their relatively high costs. Additionally, most of coating materials used to produce SRFs are nonbiodegradable and toxic to the soil. In this context, we utilized various biopolymers such as tamarind, xanthan, and guar gums together with diatomite to coat urea fertilizer granules. In this study, tamarind–urea-diatomite (TUD), guar–urea-diatomite (GUD), and xanthan–urea-diatomite (XUD) SRF granules were prepared in the presence of epichlorohydrin as crosslinker. The nutrients slow release behavior and the water retention capacity of these SRFs in soil were determined. The water absorbency of the product was 89% TUD, 93% GUD, and 142% XUD of its own weight when it was allowed to swell in tap water at room temperature for 2 h. Poly(methacrylic acid) was applied as the outermost layer of XUD to improve the nitrogen slow release efficiency of XUD SRFs. The results showed that the product had an excellent nutrients slow release property of 79.5% and good water retention capacity of 62.9% after 28 days. This suggested that XUDM could effectively improve the utilization of fertilizer. Furthermore, being biodegradable and low cost could be beneficial in agricultural and horticultural applications.

Langues : Anglais (eng) Tags : 'Coating material' Varnish 'Ester polymer' Polyurethane 'Paint film' Biodegradation Microorganism 'Experimental study' Index. décimale : 667.9 Revêtements et enduits Résumé : In order to characterize the degradation behaviour of six commercial varnishes for wood, three polyester-based and three polyurethane-based, varnishes were incubated with a microbial pool. The study was carried out analyzing the ability of micro-organisms to grow utilizing the varnishes as substrate. Microbial growths were effective with all tested varnishes and they demonstrated a different trend depending on the type of varnish and the used media.
