Revêtements -- Législation -- EuropeTags : 'Anti-biofouling' Barnacle 'Législation européenne' 'Peinture non toxique' Index. décimale : 667.9 Revêtements et enduits Résumé : The question of how to tackle the problem of biofouling with coatings, while complying with increasingly stringent international regulations on water polllution, has proved problematic for the marine transport industry : the challenge is how to develop a non-toxic solution that reduces the adhesive strength of barnacles, sea squirts and other marine animals, without killing them or releasing toxic by-products. Biofouling can be a real headache for the marine industry ; for example, a ship laden with unwanted and adhesive passengers can use up to 40 % more fuel just to match the speed of a barnacle-free ship. The problem has become more urgent since the International Maritime Organization (IMO) International Convention on the Control of Harmful Antifouling Systems on Ships came into force in September 2008. IMO is continuing to urge all its members to ratify this convention while researchers simultaneously seek to fill the "technology gap" and develop novel anti-biofouling coatings, which work through their physicochemical properties rather than the release of biocides.

Titre : Scrash-proofing : Towards a standard scrash resistance test for parquet coatings Type de document : texte imprimé Auteurs : Rico Emmler, Auteur ; Rolf Nothhelfer-Richter, Auteur Année de publication : 2005 Article en page(s) : p. 36-38 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Test methods - Scratch resistance is one of the key performance parameters on wood coatings systems, particularly in parquet coatings. However, as yet no convining standard method exists that at the same time allows to differentiate between different coatings systems, correlates well with scratch resistance performance in real life, is easily applicable and not too costly. The study presented here aims at developing such a test. Note de contenu : Single scratch tests - too unpredictive or too costly / Comparing multiple scratch tests : The Martindale procedure - Linear Scratch Procedure - Rota Hub Scratch Test / Coatings and scrub materials / Testing methods and parameters / Surface structures on used parquet coatings / Martindale scrub agents differ in effectiveness / Applied force needs to be calibrated to the scrub material / Scrub velocity does not matter - the number of cycles does / Gloss measurement distinguishes most clearly / Two drafted test procedures yield good differentiation.

Vernis bi-composantIndex. décimale : 667.9 Revêtements et enduits Résumé : The new generation clear coats introduced in the automotive industry have improved scratch and mar resistance. It is believed that those properties are related to the introduction of new binder technologies leading to higher film cross-link densities. This was relatively easy to accomplish in the automotive industry because baking temperatures are well above the glass-transition temperature (Tg) of the final clear coat film. In car repair coatings, the cross-linking takes place under conditions where the intermediate and/or final film Tg values are above the curing temperature. Such formulations result in vitrification during the drying process, a transition during which chemical cure and solvent release are slowed down substantially. The chemical cure can be improved through more reactive and/or higher functional binders, but this shifts the gel point to shorter times in the drying cycle which may lead to more solvent entrapment, resulting in low film hardnesses and paint defects. This paper describes the overall properties of 2K-refinish clear coats based on linear versus branched, random and graft acrylic polyols. The authors will try to correlate overall properties with theoretical predictions and practical results.

Réticulation (polymérisation)Index. décimale : 667.9 Revêtements et enduits Résumé : Scratch characteristics and self-recovery behaviors of automotive clearcoats including newly designed silane-modified blocked polyisocyanate (SMBI)1 as an organic–inorganic hybrid crosslinker were compared with those with the commercially well-known crosslinkers such as blocked HDI-based and blocked IPDI-based polyisocyanates. To extensively scrutinize the effects of various crosslinkers with different chemical structures on the chemical and mechanical properties of clearcoats themselves, rigid-body pendulum tester analysis, creep-recovery analysis, and FTIR analysis were performed, resulting in a noticeable variation in curing features and crosslinking networks. Employing the overall coating systems by depositing clearcoats with different crosslinkers above the same undercoats on galvanized steel, the scratch behaviors on the surface of the outermost clearcoat layer were examined via the nano-scratch tester for scratch depth profiles and atomic force microscopy for three-dimensional scratch images, under various self-reflow temperatures and duration time periods. The results demonstrated that the SMBI crosslinker induced a considerably higher degree of crosslinked networks, through the reaction of urethane bonds and silanol bonds in clearcoats, in comparison with the blocked HDI and IPDI polyisocyanates. Also, the recoverable behaviors of scratched clearcoats containing different blocked polyisocyanates were affected by the intrinsic chemical structures of crosslinkers, as well as scratch-recovery conditions such as external temperatures and duration times.

SiliceLa silice est la forme naturelle du dioxyde de silicium (SiO2) qui entre dans la composition de nombreux minéraux.
La silice existe à l'état libre sous différentes formes cristallines ou amorphes et à l'état combiné dans les silicates, les groupes SiO2 étant alors liés à d'autres atomes (Al : Aluminium, Fe : Fer, Mg : Magnésium, Ca : Calcium, Na : Sodium, K : Potassium...).
Les silicates sont les constituants principaux du manteau et de l'écorce terrestre. La silice libre est également très abondante dans la nature, sous forme de quartz, de calcédoine et de terre de diatomée. La silice représente 60,6 % de la masse de la croûte terrestre continentale.

Transition vitreuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Incorporating metal-oxide nanoparticles such as nano-alumina and nano-silica into polymer coatings to enhance mechanical durability is widely utilized in the current antiscratch and mar technologies. In this article, a quantitative study of the effect of a nano-alumina additive on the surface mechanical properties and scratch behavior of a two-part polyurethane coating is reported. An instrumented indenter with a conical diamond tip is used to measure surface mechanical properties (modulus and hardness) and to perform scratch tests, over a wide range of scratch loads. The scratch behavior in terms of the onset of elastic–plastic transition and scratch morphology were characterized by laser scanning confocal microscopy. The scratch results were correlated to the surface mechanical properties and relevant bulk material properties to understand the overall scratch behavior of the coatings. The results show that the scratch behavior of the coatings depends strongly on the concentration of nano-alumina.
