glue for tv application

[boris\]

Hello, I have to design a support for mounting an optic for an application in the vacuum thermo chamber. optics is of trade, material zerodus, and given the design specifications, I chose ccom material for invar support, given the small variation of cte between the two. I humbly ask if someone has ever used structural "colles" for TV application.

Thank you in advance.

hi boris, useful starting references can be: http://esmat.esa.int/services/preferred_lists/materials_lists/materials_lists_9.html and data sheet of products found on the network; among the most used and quoted in literature 3m ec2216 b/a, nusil silicone technology, dc 93-500, solithane 113, heralds 2014; to have samples to be tested you must arouse the commercial interest but some have versions "commercial" not "space-grade" available online also on the market of aeronautical supplies
