Colles:Adhésifs Diodes électroluminescentes Photoréticulation Polyacryliques Réticulation à l'humidité 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 : |
Light-cure technology continues to be the fastest-growing adhesive category selected by medical device manufacturers worldwide. With its rapid cure and wide product offering, there is a category and product to suit most device applications.
Recent advancements - including high-wavelength visible acrylics, light and light/moisture curing silicones, and flexible acrylics - have further broadened the applicability of light-cure adhesive technology for medical device assembly challenges.
New product development of both adhesives and associated cure systems is ongoing. New versions of LED-based spot-curing units are on the horizon, offering high intensity output in 365 nm, 405 nm and > 450 nm wavelengths. Wider-area LED curing systems are expected to hit the marketplace this year that offer cure areas of approximately four square inches.
Adhesive development continues as well with alternate fluorescent agents for pre- and post-cure adhesive detection, additional high-wavelength visible curing adhesives, and light-curing epoxies that meet ISO-10993 biocompatibility requirements. |
