Revêtements multicouchesIndex. décimale : 667.9 Revêtements et enduits Résumé : An innovative technology that offers im-proved performance, saves material and labour costs and eliminates the need for an epoxy primer coat. A single compo-nent polymeric penetrant reacts with the corroded base metal to form a long-lasting bond and increase the structure's useful service life. This coating technology has far-reaching potential, for example in off-shore applications, chemical processing and automotive refinishes. Note de contenu : - Experimental

PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.

Rhéologie
ThixotropieIndex. décimale : 667.9 Revêtements et enduits Résumé : Recent changes have occurred to the amount of solvent
used in industrial coatings, particularly maintenance
and marine coatings. Over the past few years the amount of solvent used in these coatings has decreased significantly. This has affected the properties of the coatings and the application techniques. As the solids contents of industrial coatings increase the number of applications has decreased, which has provided cost savings for the customer. Lower solvent levels have also helped to meet tighter global emission regulations and the use of HAPS-free solvents allow some coatings manufacturers to daim 100% solids status.
Although the decrease of solvent has proved a benefit to manufacturers and customers, it has had a wide impact on the use of rheology modifiers and their ability to provide enough viscosity and sag resistance and also intercoat adhesion effects. In older solvent-rich formulations, the rheology agents would disperse easily, the solvent coating would wet out on the substrats and would adhere well.
In the current low solvent environment these obstacles have to be overcome.Note de contenu : - Organic rheological additives in high solids

HydroxyleEn chimie organique, un hydroxyle (ou oxhydryle) peut désigner deux entités.
Un groupement -OH, appelé aussi hydroxy, qui se rencontre en particulier dans les alcools et les phénols.
Un radical : HO^{\bullet}. Il est produit par exemple lors de réactions de dissociation de peroxydes, en présence d'ions de métaux de transition (Fe(II), Cu(I), réaction de Fenton), de chauffage ou de rayonnement.

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Statistical methods were used to develop hydroxy functional acrylic emulsions for use with a water-dispersible polyisocyanate crosslinker. The resulting two-component waterborne coating systems were optimized for kitchen cabinet and office furniture applications. Key performance criteria included appearance and aesthetics pot life, print and mar resistance, and chemical resistance involving both Kitchen Cabinet Manufacturers, Association (KCMA) and office furniture requirements. Statistical analysis revealed several strong correlations between acrylic emulsion hydroxy level, particle size, composition Tg and polymerization process and wood coating performance. For example, smaller acrylic emulsion particle size was found to yield many performance benefits with few detriments. Coating formulation variables were also found to be significant. Ultimate coating hardness increased with water-dispersible polyisocyanate level, yet early hardness readings correlated negatively with water-dispersible polyisocyanate level. Plasticization and crosslinking effects were thought to be responsible. Higher ethylene glycol monbutyl ether (EB) coalescent level was found to correlate negatively with coating hardness, suggesting a reaction between the EB hydroxyl group and the water-dispersible polyisocyanate, resulting in plasticization of the coating.

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).Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Kaneka's 2K STPE/Epoxy technology enables the development of coating and adhesive products that provide a balanced trinity of strength, flexibility and adhesion. Given these unique benefits, 2K STPE/ Epoxy systems can be used as a flexible primer in a multilayer waterproofing system to better accommodate structural movement, or as a high strength, flexible adhesive to withstand substrate movement. Moreover, the exceptional wet adhesion retention on concrete indicated that a 2K STPE/Epoxy formulation could provide improved adhesion performance to structures where frequent water exposure might be an issue. Kaneka's 2K STPE/ Epoxy technology might be the solution that could resolve a multitude of unmet needs in both the construction and the industrial markets. Note de contenu : - Impact of additives
