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 : |
Laminating adhesives are used for bonding two substrates together. They can be used in a variety of applications, such as food packaging, aerospace, automobiles, electronics or solar panels. The major technologies include solventborne, waterborne, two-component urethanes and UV-curable resins. UV technology is rapidly gaining acceptance in a variety of industries due to its environmental and economic advantages.
During recent years, market demand has been strong for liquid optically clear adhesives (LOCA) for display or touchscreen applications. Key performance requirements include strong bonding strength to the substrates, excellent reliability, high optical clarity and superior moisture resistance. For high-quality displays, low dielectric constant bonding adhesives are also necessary.
The moisture barrier performance of UV/EB-cured materials has been discussed in previous publications.2-3 Here, we will examine the durability properties of UV-cured acrylates under three weathering conditions, including Q-Panel laboratory ultraviolet (QUV) testing, 85°C/85% relative humidity and freeze-thaw cycles. The key properties evaluated are optical clarity characterized by percentage of UV-Vis transmission and T-peel strength. In the end, we will discuss the dielectric properties of different types of oligomers. |
