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).
Surfaces (technologie)Index. décimale : 667.9 Revêtements et enduits Résumé : Silicone-modified polyacrylates form a new class of surface-modifying additives, typically containing much lower silicone levels than established silicone additives. The flexibility of the molecular design allows properties such as hydrphobicity, anti-blocking, anti-cratering, recoatability and levelling to be adjusted very precisely.

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Around 40% of the global industrial wood coatings market is based on traditional solvent-borne polyurethane technology. Water-borne polyurethane systems are high performance and en-vironmentally compatible but their in-herently slower drying has limited the market shift towards this low emission alternative. A novel hybrid hydrophilic polyisocyanate offers a fast-drying and promising solution. Note de contenu : - Hardener is key to developing fast crosslinkers
- Novel HDI-TDI hardener for faster curing of 2K WB systems
- Anionic hydrophilisation proves effective
- Aromatic content
- Faster cure with minimal compromise
- Drying time comparable to 2K SB standard
- More environmentally friendly solutions now possible

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
UrethanesIndex. décimale : 667.9 Revêtements et enduits Résumé : The rheological properties of an industrial coating, adhesive or sealant are vital to its success. A well formulated industrial coating, adhesive or sealant has balanced rheological properties, easy but controlled application, good Sag or slump resistance and storage stability. The thickeners incorporated in the coating, adhesive or sealant formulations provide the ma nufacturers with the a bi lity to design the rheological characteristics they need fora specific end use. Organic thixotropes are castor oil or polyamide-based materials that are especially useful in systems, such as industrial coatings, construction sealants, caulks, adhesives and mastics. These additives provide outstanding efficiency for shear thinning, viscosity build, Sag control and pigment suspension. However, the high activation temperature is sometimes a deterrent for broader use. In this paper, we present a new generation of highly efficient organic thixotrope-based thickeners that can be activated at significantly lower temperatures. These new materials can be successfully incorporated in industrial coatings or sealant formulas for better viscosity build, Sag resistance and higher extrusion rates. They display a wider process window and require less energy and time in production which can result in lower costs.
