Sulfate de baryumIndex. décimale : 667.9 Revêtements et enduits Résumé : Research and development teams have a vast array of fillers, pigments and dispersing and wetting additives to choose from when developing new coatings. The authors aimed to simplify this process by creating a novel nano-additive that can be used as a universal stabilising component. The resulting additive and process technology provides a way of reducing development time and undesirable side effects. Note de contenu : - Improve predictabitility to aid coating development

Stabilisants (chimie)Index. décimale : 667.9 Revêtements et enduits Résumé : The author discusses the development of Disperbyk-2155, which provides a high molecular weight for stabilisation and solids content.
Due to its innovative sphere-like structure, Disperbyl-2155 combines high molecular weight with high solids content, therefore opening up new horizons in the wetting and dispersing of pigments in high solid as weel as in conventional coating systems. It displays outstanding deflocculation and stabilisation properties, effectively reducing mill base viscosity, is storage-stable and shows wide compatibility with many different types of resin systems. The next generation polyurethane wetting and dispersing additive Disperbyk-2155 is designed to be used in pigment concentrates for automotive coatings, floor coatings (based on polyurethane and epoxy), polyurethane foams and thanks to its 100% solids content also for solvent-free UV systems. In addition, the additive has been successfully used in co-grinding systems.Note de contenu : - Pigment stabilisation in high solid systems

SurfactantsIndex. décimale : 667.9 Revêtements et enduits Résumé : There are waterborne binders with enhanced dry film properties and present application data comparing conventional and copolymerisable surfactants.
Surfactants are essential components in the synthesis of emulsion polymers for controlling particle size and colloidal stability of the latex and in downstream formulations. Common surfactants used in latex synthesis, however, have poor compatibility with the hydrophobic polymer phase. Surfactant desorption in the wet state can cause particle flocculation upon storage or handling. Poor stability during film formation has a dramatic effect on dry film properties. Porous films result with poor pigment binding and protective properties. Phase separation and accumulation of surfactant into hydrophilic domains during film formation affects water whitening, blocking resistance and mechanical properties.
Non-migratory surfactants (NMS) become grafted on to the surface of polymer particles. Latex stability is enhanced, which positively affects shelf life, formulation ease and barrier properties.
Use of reactive surfactants is relevant for various application areas :
- Architectural coatings with better pigment binding properties
- Protective coatings with superior barrier properties or lower water diffusion rates
- Pressure sensitive adhesives with superior mechanical properties
This paper presents application data comparing conventional and copolymerisable surfactants.
NMS technology allows development of waterborne polylmer systems and dry films that does notshow the drawbacks commonly associated with the presence of surfactants.Note de contenu : - SURFACTANTS AS ROOT CAUSE FOR POOR PERFORMANCE

Stabilisants (chimie)Index. décimale : 667.6 Peintures Résumé : Alkyds resins are used frequently in industrial coatings. Despite the advantages of these properties there is one major drawback with using alkyd resins. Degradation may occur over a relatively short period of time when alkyds are exposed to ultraviolet (UV) light radiation from natural sunlight. The clear coat containing UV absorbers and light stabilisers (N-OR HALS) is commonly applied to the surface for protection.
Waterborne alkyds coatings - the green coatings - have been developed to replace conventional alkyd coatings with VOC emissions. It could be a challenge when light stabilisers are required to protect coatings to UV degradation.
This paper is a comparison study of two different waterborne light stabilisers, which are N-R and N-OR HALS, mixed with waterborne alkyd coating. N-R HALS is basic and N-OR HALS is suitable to use in waterborne acidic alkyd coating. Design of Experiment (DOE) was used in this study. Eversorb AQ6 is a waterborne UV absorber and Eversorb AS5 is N-OR HALS that was investigated in this model. The results confirmed that by increasing the concentration of Eversorb AQ5 and Eversorb AQ6 in the top coat, it can effectively protect from UV light degradation. Furthermore, data also showed that by increasing the coating thickness, the weatherability of coating can also be improved to some degree.En ligne : https://drive.google.com/file/d/16k2Vu41mTXXfOnJSV_qNFjWPuAuEZz4Q/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=21506
