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.

PolychloroprèneIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : The unique property profile of polychloroprenes (CR) makes these products indispensable in the field of solventborne contact adhesives for a large number of applications. The performance of the bonds can be significantly improved by crosslinking with isocyanates.
Because of mounting ecological requirements and more stringent regulations on occupational health, there is an increasing trend towards the development of solvent-free adhesives based on aqueous alkaline CR dispersions. Here, however, the scope of application is limited as it has not so far been possible to adequately satisfy demands for products for bonding non-absorbent substrates or for high heat resistance.
This article describes new CR dispersions with a modified polymer structure that satisfy the increasingly strict ecological requirements on these modern adhesives in line with the "Responsible care" concept. Used in combination with a new dispersible crosslinking isocyanate that is also suitable for strongly alkaline CR adhesive dispersions and produced by a suitable compounding process, these dispersions open up new areas of application that will be illustrated in examples.Note de contenu : - Polymerization

solvantsIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Adhesive selectors, whether published guides or human, typically begin with determining which adhesive product or products will adhere to the substrate. That approach is necessary for repair applications, and may even be necessary for fixing a production issue on-the-fly. Engineers working in assembly need to consider the functionality of the device first. Adjusting substrate materials, processes, or joint designs may also be considered, but not automatically required. Next, testing to verify performance is necessary—and strongly recommended.

ThermocinétiqueIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Functionalized polysiloxanes yield well dispersed microcomposites with higher volume percentages of filler than possible with PDMS resins. The polar polysiloxanes interact strongly with polar conductive fillers via specific interactions between the polysiloxane pendent electron donating groups and the oxide layer on the filler particulates. Specific adhesion and hydrogen bonding capabilities of functional polysiloxanes were confirmed by TEM, XPS, NMR and peel adhesion studies.
The initial network properties of PCPMS/SiO2-AIN microcomposites are promising as a novel thermally conductive adhesion. Polysiloxane adhesion microcomposite networks are being investigated with controlled amounts of functional groups as candidates for thermally conductives adhesives. The phosphine oxide substituted polysiloxanes, Tg-113 degrees C, have also been recognized as promising adhesive binders since preliminary data suggests they may yield quality dispersions with up to 75vol. percent conductive filler while remaining processable.Note de contenu : - Functional polysiloxanes with pendent electron donating groups

Stabilisant à la lumière de type amine encombrée
Stabilisants (chimie)Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Stabilizing additives such as antioxidants (AOs), ultraviolet (UV) absorbers, and hindered amine light stabilizers enable formulators to create durable adhesives and sealants, thereby extending the life of adhesively bonded goods. These high-performance products are key contributors to sustainable product development and help to promote the advancement of a circular economy.
Although often invisible, adhesives and sealants are part of our daily lives. They ensure that our food is packaged and advertised safely, that our houses are wind- and waterproof, and that our communication and mobility needs are served in safe and efficient ways. Thousands of everyday items such as mobile phones, washing machines, personal hygiene products, shoes, clothing, building products, batteries, automobiles, rail cars, ships, and airplanes are nowadays only practical due to the use of high-performing adhesives and sealants.
A broad range of chemistries and polymeric organic materials is required to cover the multitude of adhesive and sealant bonding parameters. Adhesive formulators have taken on the challenge and created the art of matching bonding performance requirements with products and application processes. Their core expertise lies in selecting chemistries, curing mechanisms, and raw materials and combining them to create a product that can be processed efficiently and economically in the respective application environment. Polymers and organic materials have an inherent tendency to change properties and degrade throughout their value chain—from manufacturing, processing, transportation, and storage right to end use.Note de contenu : - Incorporation and processing
