Titre : Environmental solutions without solutions : Optimised TGIC-free low bake system offers good exterior durability Type de document : texte imprimé Auteurs : Luc Moens, Auteur ; Erwin Bauters, Auteur ; Marc Van Muylder, Auteur Année de publication : 2010 Article en page(s) : p. 25-28 Langues : Anglais (eng) Catégories : Résistance aux conditions climatiques
RevêtementsTags : 'Revêtement poudre' extérieur' Durabilité 'Résistance thermique' Polyesters 'Isocyanurate de triglycidyle(TGIC)' Index. décimale : 667.9 Revêtements et enduits Résumé : Though low-bake powder coatings have been used satisfactorily on MDF and some plastics, achieving exterior durability generally requires using either high stoving temperatures or the hazardous crosslinker TGIC. Specific blends of two polyesters and two glycidyl-functional crosslinkers now provides TGIC-free high quality powder coating finishes with "standard' outdoor durability at curing temperatures down to 120°C. Note de contenu : - Challenges in achieving exterior durability.
- Alternative solutions for low temperature curing.
- Careful blending optimises low-bake formulation.
- Preparation and testing of sample powders.
- Lower viscosity during cure improves appearance.
- Good results obtained in accelerated weathering tests.
- Low-bake powders open up new markets.En ligne : https://drive.google.com/file/d/1lXam14Wp4gJxDh8rZiXAfVXX6TRXe9S-/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=9606

Titre : Flexible super-durable polyester based powder coatings Type de document : texte imprimé Auteurs : yVES Merck, Auteur ; Daniel Maetens, Auteur ; Luc Moens, Auteur ; Kris Buysens, Auteur Année de publication : 1999 Article en page(s) : p. 18-24 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : A new types of carboxyl terminated polyester resin, combining excellent flexibility with outstanding outdoor durability when used in pigmented powder coatings, has been developed. The resin can be cross-linked with either triglycidylisocyanurate (TGIC) or a hydroxyalkylamide type hardener and will be known as flexible super-durable polyester. Note de contenu : - Testing the durability of coating
- Resin characteristics and preparation of the coatings
- Flexibility : Usable in areas such as coil coating
- Weathering resistance
- A good correlation between QUV-A and Florida natural exposure
- Corrosion resistance is comparable to classic superdurable systems
- Usable in architecture in tropical and sub-tropical environmentsEn ligne : https://drive.google.com/file/d/1e7wtQEquA-7KF4-NTTUAJbgmoFy5ClAM/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11222

Titre : A new polyester resin for béta-hydroxyalkylamide powder coatings Type de document : texte imprimé Auteurs : Daniel Maetens, Auteur ; Luc Moens, Auteur ; Luc Boogaerts, Auteur ; Kris Buysens, Auteur Année de publication : 1999 Article en page(s) : p. 26-33 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : A carbonyl terminated polyester resin, of novel molecular composition , has been developed for use in powder coatings containing beta-hydroxyalkylamide ( HAA) type hardeners. The design of this new resin enables powders to be formulated that exhibit outsatnding flow without sacrificing other properties, such as acid rain resistance, or colour stability on overbake. Note de contenu : - Safe alternatives for TGIC
- All advantages are in one and the same polyester resin
- Low viscosity with an excellent hydrolysis/UV resistance is very difficult to design
- Reactivity only depends on the structure of the polyester
- The new resin should get outstanding flow with excellent corrosion and UV resistance
- Materials
- Formulations/ processing
- Flow curves
- Wave-scan measurements
- Corrosion resistance
- Weather resistance
- Overbaking/ gasoven resistance
- Flexibility
- Visco-elastic behaviour can be described using the storage and the loss modulus
- Flow behaviour and general appearance of " Primid XL-552" based powder coatings
- Flow behaviour and general appearance of "Primid QM-1260" basedf powder coatings
- The best flow is obtained with the new resin
- Degassing during curing
- New resin shows the lowest melt viscosity and the lowest reactivity
- New system shows hydrolytic stability
- Monomer composition does not prove any negative influence of UV-resistance
- Overbaking and gasoven resistance
- New resin is found to be as good as for the references considering mechanical propertiesEn ligne : https://drive.google.com/file/d/1kDUDSla0lmdozsrl2ssq4dbZuGE9T4xH/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11187
