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).

| Résumé : |
Description the silicon-based technologies (SBTs) that advance the coatings industry and empower formulators to offer new functionality in various applications. In the past ten years, the number of new patents related to silicon-based materials for paints and coatings has increased exponentially, specifically those related to solving the problems traditionally addressed by SBTs, such as foam control, wetting and adhesion promotion. Dow Corning led many of these efforts and produces products for use in a wide range of coatings applications, including primers, heat-resistant coatings, industrial maintenance coatings, hygienic coatings, marine coatings, biocidal coatings, anti-fouling coatings, abrasion-resistant coatings, automotive clear coats and architectural coatings. Used as the primary component in a formulation or as an additive, these products impart enhanced performance attributes in high-performance applications.
SBTs provide characteristics and performance attributes not foud in traditional organic coatings. Formulators use SBTs to differentiate their products and offer functionality for specific market needs. These include the need for low-VOC formulations; greater resistance to water, oil and stains; enhanced weatherability; increased thermal resistance; and superior texturing. SBTs are also non-toxic and provide utility at very low-use levels. Finally, many silicon materials combine easily with organic monomers and polymers, allowing formulators to develop specialised blends with the functionality of both organic and non-organic materials. |
