Polyméthacrylate de méthyleLe poly(méthacrylate de méthyle) (souvent abrégé en PMMA, de l'anglais Poly(methyl methacrylate)) est un polymère thermoplastique transparent obtenu par polyaddition dont le monomère est le méthacrylate de méthyle (MMA). Ce polymère est plus connu sous son premier nom commercial de Plexiglas (nom déposé), même si le leader global du PMMA est Altuglas International9 du groupe Arkema, sous le nom commercial Altuglas. Il est également vendu sous les noms commerciaux Lucite, Crystalite, Perspex ou Nudec.
Revêtement auto-nettoyant:Peinture auto-nettoyanteIndex. décimale : 667.9 Revêtements et enduits Résumé : In recent years, there has been a considerable amount of work on the development of contamination resistant coatings. Key advances in the understanding and fabrication of surfaces with controlled wetting properties has a major role to play in creating contamination-free or easy to clean surfaces. Two principal ways are at our disposal to understand surface of self cleaning materials which work by the removal of dirt by either film or droplet flow. When it comes to protecting building facades from the possible contaminants such as dirt, exhaust fumes containing oily components, minimal spotting or streaking and good weathering resistance self cleaning hydrophilic coatings comes into the picture.
Self cleaning nanocoatings use the advantages of Ti02's superhydrophilic behavior and then reduces dirt pick up and improves cleanability.
This paper describes the preparation, characterization & uses of organic-inorganic hybrid nanocoatings using Ti02 & SiO2 nanoparticles.Note de contenu : - Dirt and water-repellent "easy-to-clean" surfaces blessed by nanotechnology

In each instance, the addition of the polyisocyanate crosslinker improved the elevated temperature performance of the two component adhesive.
As with most two component systems, polyisocyanate crosslinkers have pot life issues that need to be managed in order to obtain peak performance. Crosslinkers are available with a range of reactivities, hydrophilic content and cost that allow performance to be adjusted for the specific adhesive application.Note de contenu : - Polyisocyanate

SiliconesLes silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki).
Tension superficielleIndex. décimale : 667.9 Revêtements et enduits Résumé : Modern waterborne and conventional solvent-based coatings face a number of technical and commercial challenges. Additives are increasingly important for enabling the coating formulator to reach these ever-growing demands and advance the technology. Wetting, leveling, slip, recoatability or easy-to-clean properties are strongly influenced by surface-active additives. These surface additives migrate toward the coating/air or coating/substrate interface and tailor the surface or interface behavior. A unique possibility of building up multi-layer coating systems is to increase the surface energy of an underlying coating using hydrophilic additives, which positively affects the wetting of the subsequent coating layer.
