Intumescence (chimie) Marines (peinture) Structures offshore -- Revêtements protecteurs Index. décimale : 667.9 Revêtements et enduits Résumé : A cryogenic spill can be similar to a hydrocarbon fire in terms of thermal shock. It is, therefore, essential that intumescent epoxy coatings must protect from extreme cold, as well as fire. Traditionally, flexible epoxy passive fire protection, PFP, coatings have been used in environments where exterior or durability and corrosion resistance are required. The difference in these coatings to standard paints is that they are applied at much higher film thicknesses and, as such, they can be used without the need for active methods of protection such as the activation of a sprinkler system. Many companies working in offshore oil and gas exploration are aware of the importance of using fire-protective coatings on their fixed and floating assets and will typically select a coatings system that will function in a specific operational environment, eg, where loading, storing or unloading cryogenically-cooled liquids, remains a challenging process.

New developments in elastomeric masonry coatings / Miriam Peralta in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 204, N° 4594 (03/2014)  

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 204, N° 4594 (03/2014) . - p. 22-27 Titre : New developments in elastomeric masonry coatings Type de document : texte imprimé Auteurs : Miriam Peralta, Auteur ; Darlene Rota, Auteur ; Kevin Quinn, Auteur ; Thomas Zagore, Auteur Année de publication : 2014 Article en page(s) : p. 22-27 Langues : Anglais (eng) Catégories : Applications extérieures Copolymères Couleurs -- Stabilité Elastomères Matériaux cimentaires -- Revêtements protecteurs Polyacryliques Résistance à l'efflorescence Résistance chimique Revêtement mural:Peinture murale Revêtements -- Propriétés mécaniques:Peinture -- Propriétés mécaniques Revêtements en bâtiment:Peinture en bâtiment Index. décimale : 667.9 Revêtements et enduits Résumé : There is an increasing demand in the construction industry for environmentally friendly building products, as well as requirements for more durable coatings with enhanced performance. New developments and advances in synthesis capabilities provide the market with a myriad of polymers for the vertical elastomeric masonry coatings market. New polymer technology has been developed without the addition of alkyl-phenolethoxylate surfactants, NMP or formaldehyde that enables the formulation of low VOC elastomeric coatings for vertical masonry applications. Coatings based on the new technology have the ability to withstand high pH environments due to improvements in alkali resistance. The high level of alkali resistance gives the coating the ability to be used as self-priming coating, primer or topcoat. New elastomeric coatings exhibit excellent water and efflorescence resistance, reducing the lifetime maintenance requirements and costs associated with preparing and recoating. Lower water intake of the coating prevents water penetration into the building structure and enhances wet adhesion of the topcoat at the masonry substrate. Improved water resistance and adhesion properties protect the structure from water damage. High tensile and elongation provides coatings with superior crack resistance when compared to conventional architectural coatings. In addition, improved weathering and resistance to dirt pick-up keep surfaces clean, with a long-lasting, fresh appearance. This technology is recommended for use in elastomeric primers and topcoats for masonry façades, as well as new/hot, aged or repainted surfaces including exterior walls, concrete, block, brick, stucco, fibre cement and exterior insulation and finish systems (EIFS). Modifications to traditional styrene acrylic and all-acrylic chemistries have been implemented into development of new polymers for elastomeric applications.

Sustainable solutions for decorative interior paint / Jonathan Doll in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 204, N° 4594 (03/2014)  

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 204, N° 4594 (03/2014) . - p. 28-29 Titre : Sustainable solutions for decorative interior paint Type de document : texte imprimé Auteurs : Jonathan Doll, Auteur ; Jennifer Louis, Auteur ; Frank Sensoli, Auteur Année de publication : 2014 Article en page(s) : p. 28-29 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Nacre La nacre est le revêtement intérieur de certaines coquilles de mollusque, composé de cristaux d'aragonite et de conchyoline, aux reflets irisés. C'est un produit recherché depuis longtemps pour la décoration, la marqueterie, la confection de bijoux ou de boutons, au point que certains coquillages tels que les ormeaux ont localement disparu. Certains sont élevés pour la nacre. La nacre résiste mieux aux acides que la coquille et se reconstitue lorsqu'elle est percée ou abîmée chez le coquillage vivant. Lorsqu'un élément étranger irritant entre dans la coquille de ces mollusques, ceux-ci secrètent également de la nacre couche après couche tout autour afin de s'en protéger, formant ainsi une ou plusieurs perles. Contrairement aux autres couches de la coquille, la nacre est synthétisée par le mollusque tout au long de sa vie. La nacre fait partie des matières organique selon la HBJO.

For the most part, paint manufacturers produce interior paint for home décor using aqueous colour tints. A variety of colour dispersions or tints are mixed with a base paint to produce an unlimited variety of colours. In dry form, pearlescent pigments contribute no volatile organic compounds (VOCs) to the final paint. However, the flaky nature of pearl pigments causes handling or "dusting" issues that exclude them from most point of purchase paint applications. Aqueous pearl pigment dispersions can be used to address this handling issues. The key technical requirement for these preparations is that they must be non-settling and easy to disperse. Due to ever tightening regulations, another key requirement is the pearl dispersion must have extremely low VOC concentration. In this paper, sustainable pearlescent pigment dispersions are introduced based on SunMICA effect pigments from Sun Chemical. These dispersions are designed for interior architectural paints requiring high pigment loading and outstanding dispersability. These products can be used in tints or primers and are suited for all types of aqueous interior paints.

Meeting current and future legislations / Carlo Testa in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 204, N° 4594 (03/2014)  

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 204, N° 4594 (03/2014) . - p. 30-31 Titre : Meeting current and future legislations Type de document : texte imprimé Auteurs : Carlo Testa, Auteur ; Louise Taylor, Auteur ; Ralf Taube, Auteur Année de publication : 2014 Article en page(s) : p. 30-31 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Air intérieur -- Pollution Atmosphère -- Pollution -- Lutte contre Coalescence (Sciences physiques) Réduction des composés organiques volatils Revêtements -- Additifs:Peinture -- Additifs Revêtements en bâtiment:Peinture en bâtiment Revêtements intérieurs:Peinture intérieure Index. décimale : 667.9 Revêtements et enduits Résumé : In recent years voluntary and mandatory schemes have been put in place to improve indoor air quality. Over the past few years, several global voluntary and mandatory schemes have been introduced to improve indoor air quality by limiting emissions from materials. In many cases it is not feasible or desirable to lower the overall emissions of a coating by simply reducing or completely removing the coalescents present in the formulation as this will have a negative effect on the application, performance and quality of the paint. Eastman is now offering an enhanced coalescent portfolio to provide the coatings formulator with more options for designing a range of formulations from traditional coalesced coating systems to the latest low emission coatings. While many paints that meet the highest emission standards can be formulated with traditional coalescents, adding a low emission coalescent to Eastman's portfolio allows formulators options for transitioning away from volatile to non-volatile coalescents when required. Rather than spending resources and lime re-formulating paints based on low Tg binders, traditional volatile coalescents can simply be replaced or used in combination with, new low- or non-emitting coalescents. The poor reproducibility of emission testing is well known within the industry. Formulators often choose to send their samples to more than one external laboratory to validate their emission results. The poor reproducibility can lead to unnecessary reformulation work and further costs associated with re-testing paint samples at more than one accredited test laboratory. No matter how poor the reproducibility of the testing, formulators who opt to formulate with Optifilm enhancer 400, have the reassurance that the contribution of this low emitting coalescent to the emission profile of the paint is always negligible. Improving indoor air quality and lowering emissions from indoor paints, particularly wall and ceiling paints, is a major challenge for the coatings industry and designing a paint system that can conform to these schemes has become increasingly challenging.

Aqueous dispersions : high purity, easy-to-use coating additives / Alexandre Giardino Carmello in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 204, N° 4594 (03/2014)  

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 204, N° 4594 (03/2014) . - p. 32-34-38 Titre : Aqueous dispersions : high purity, easy-to-use coating additives Type de document : texte imprimé Auteurs : Alexandre Giardino Carmello, Auteur ; Brian Prevo, Auteur Année de publication : 2014 Article en page(s) : p. 32-34-38 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Alumine Latex Matériaux -- Propriétés barrières Oxydes métalliques Polyacryliques Poudres Résistance à l'abrasion Revêtements en phase aqueuse -- Additifs:Peinture en phase aqueuse -- Additifs Rhéologie Silice La 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. Index. décimale : 667.9 Revêtements et enduits Résumé : The difficulty of handling, incorporating and dispersing some powder additives presents challenges to coating manufacturers employing such materials in their formulations. Furthermore, working with these powders can lead to some disadvantages including dirtiness and dust, contamination and possibly reduced performance. Cab-O-Sperse fumed metal oxide dispersions can help balance or break some of the trade-offs between processing powder additives and the final performance of the coatings formulations in which those additives are used. Cab-0- Sperse dispersions use proprietary Cabot technology to produce highly stable fumed alumina or fumed silica dispersions in water, featuring uniform particle distributions with an average size of less than 0.2 pm, differing solid contents (12 to 40%), surface charges (anionic or cationic) and pH values (4 to 10.5). This results in several advantages compared to powder products, including ease of incorporation and mixing into liquid coatings, reduced dust in the environment, less waste and reduced risk of bubbling caused by trapped air. When used in coatings, the Cab-O-Sperse product line provides increased film hardness and abrasion resistance, improved corrosion resistance and barrier properties. The Cab-O-Sperse dispersions line is presented below via comparative studies of formulations with no additives, formulations with rheological additives including dry fumed silica powder and formulations with added Cab-O-Sperse dispersions, in order to analyse their hardness, scratch resistance, transparency and rheological properties.

Sustainable alkyd-based coatings / Jo Grade in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 204, N° 4594 (03/2014)  

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 204, N° 4594 (03/2014) . - p. 36-38 Titre : Sustainable alkyd-based coatings Type de document : texte imprimé Auteurs : Jo Grade, Auteur ; Marilyn van de Velde, Auteur Année de publication : 2014 Article en page(s) : p. 36-38 Note générale : Bibliogr.

There is an increasing tendency in the market to reduce or eliminate use of solvents in decorative coatings. Waterborne latex paints, using raw materials from petrochemical resources, have largely replaced conventional solventborne alkyd resins in wall paints. For wood and metal protection however, alkyd resins remain the preferred binders, for their excellent protective properties and appearance. Even today, almost half of the European resin production for surface coatings consists of alkyd resins, despite the pressure from more 'modem' binder technologies like waterborne acrylic latexes or polyurethane dispersions. Strong arguments remain to predict a bright future for alkyd resins in surface coatings : Performance. Alkyds combine cost effectiveness with unique formulation, application and dry film properties that cannot be achieved with other resin types. Moreover, alkyds offer good pigment wetting, good penetration in porous substrates and excellent chemical resistance. This technology is easy to apply and gives high gloss finishes. Sustainability. A resin technology that is already using a large fraction from renewable, non-petrochemical raw materials. Alkyd resins can be formulated easily with up to 75% of raw materials coming from natural resources I. Legislation. The Decorative Paints directive 2004/42/CE, limiting the use of volatile organic compounds (VOC) in decorative paints and automotive refinish paints sets the targets in Europe. The directive defines maximum levels of solvents with a boiling point <250°C for a variety of coating categories and differentiates between solventborne and waterbome formulations. It is an example for voluntary schemes and legislation being implemented or prepared all over the world.
