[article]  inPAINTINDIA > Vol. LXIII, N° 7 (07/2013) . - p. 54-62 Titre : Development and performance evaluation of fluoro ethylene vinyl ether (FEVE)/polyurethane hybrid coatings Type de document : texte imprimé Auteurs : R. S. Mishra, Auteur Année de publication : 2013 Article en page(s) : p. 54-62 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Copolymère fluoroéthylène-vinyléther Matériaux hybrides -- Détérioration Microscopie à force atomique Polyuréthanes Spectroscopie d'impédance électrochimique Vieillissement Index. décimale : 667.9 Revêtements et enduits Résumé : In the present study, the efficacy of Fluoro Ethylene Vinyl Ether (FEVE) on the performance of Polyurethane coating was investigated. A series of Polyurethane (PU)/ FEVE hybrid coatings were formulated by incorporation of 2%, 5%, and 10% concentrations (by weight) of FEVE into PU coating. The structural characterization was done by ATR Fourier transform infrared spectroscopy (FTIR) spectroscopy. The prepared PU/FEVE hybrid coatings were casted on Teflon Petri dish and dried films were used to measure extent of water absorption and water vapor permeability. The prepared PU/ FEVE hybrid coatings were also applied on mild steel substrates. The ageing behavior of coated panels was evaluated by QUV Wheather-o-meter and gloss meter. The surface morphology, contact angle and corrosion resistance of coated panels were evaluated by Atomic Force Microscopy (AFM), Goniometry and Electrochemical Impedance Spectroscopy (EIS) respectively. Performance results suggest that, with increasing the concentration of FEVE, the performance of PU coating increases.

One approach receiving increasing interest in recent years has been the use of direct-to-metal (DTM) coatings can be used as replacements for two-layer primer and topcoat systems. Resin suppliers and coatings formulators are taking on the challenge of developing higher-performing, more environmentally friendly technologies for DTM applications in the industrial sector. It gives high gloss, high solid formula. It can be used in indoor and outdoor application. DTM has resistance to moderate environment including intermittent exposure to water, salt, moisture and temperature. DTM can be applied directly to new or rusted metal. It forms tough and long lasting barrier. DTM gives excellent adhesion and prevents the rust.

Environmentally friendly fluoropolymer resins for ultra-weatherable coatings / Winn Darden in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 204, N° 4593 (02/2014)

Langues : Anglais (eng) Catégories : Copolymère fluoroéthylène-vinyléther Copolymères en émulsion Résistance aux conditions climatiques Revêtements:Peinture Index. décimale : 667.9 Revêtements et enduits Résumé : Fluoroethylene vinyl ether fluoropolymer resins Fluoroethylene vinyl ether (FEVE) resins were developed in the early 1980s in an attempt to overcome some of the problems associated with conventional fluoropolymer coatings. These products have a unique polymer structure (fig. 1). This polymer structure enables the fluorinated units, which have extremely high durability, to protect adjacent chemical bonds that are not as strong and, therefore, not as resistant to degradation by UV light. By making changes in the vinyl ether portion of the polymer, coating properties like solubility, transparency, hardness, flexibility, pigment compatibility, adhesion and gloss can be varied. In addition, the vinyl ether segments can be functionalised with hydroxyl groups to allow them to be reacted with aliphatic isocyanates to form fluoro-urethanes. These characteristics allow FEVE resins to be made in a range of forms, all offering outstanding weatherability.

Fluorinated resins in self-stratifying coatings / Chris Carr in EUROPEAN COATINGS JOURNAL (ECJ), N° 4/95 (04/1995)

Walbridge, Auteur Année de publication : 1995 Article en page(s) : p. 262-266 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Copolymère fluoroéthylène-vinyléther Energie de surface Epoxydes Liants Revêtements autostratifiants:Peinture autostratifiante Index. décimale : 667.9 Revêtements et enduits Résumé : A recently completed «Brite» project was successful in developing liquid, pigmented self-stratifying coatings. These coatings contain two or more resin components with different functions which spontaneously stratify after application to the substrate. A strong driving force for stratification is the surface energy difference between the two separate phases, but other properties inflence the degree of stratification. Coatings containing an epoxy resin component (high surface energy) with a low surface energy component such as floroethylyene/vinyl ether copolymers (FEVE) proved particularly successful combinations. In nonpigmented self-stratifying systems the degree of separation was great enough to cause delamination between the two resin layers. A single pigment, which is located in the basecoat layer of the final coating, was incorporated with success and decreased the tendency to delaminate. It was found that systems containing two pigments which were intended to stratify wery more unpredictable, with the pigments often ending up distributed throughout the film.
