fluoro silicon elastomer

fluoro silicon elastomer

fluoro silicon elastomer

(OP)
Hi everybody, I have to glue a fluoro silicon sheet on a painted aluminium support. Do someone know which kind of product will permit it? or which manufacturer can satisfy me in such application?
The elastomer is an aeronautical reference 61D8.
Thanks

RE: fluoro silicon elastomer

I have a little bit of experience with this.  I'm away from the office (be back tomorrow).  My advice is to use a silicon based adhesive.  This will definetly adhear to the sheet.  The difficulty may then be the adhering to the painted surface.  When I return I'll look up the specific adhesive part numbers.

You may want to post this on a material forum as well.

Thank you Kwan for your answer.
I've got in touch with Eleco Produits (adhesive manufacturer) who have recommended me also a silicon adhesive. I will mention to not paint the glued areas.  

RE: fluoro silicon elastomer

Lolo,

I got back to the office and looked up the adhesive I've used in the past.  It's dow corning 3145, another part number for this is M46146-31XGN.  This will bond silicone to metal.  Ensure your aluminum is not painted but does have a conversion coating (alodine or anodize).  

Good Luck

Kwan,

which brand is it M46146-31XGN and 3145? I have already chosen the glue (RTV 157 from Eleco Produits)
The aluminium will have an alodine. There will be paint resists where the elastomer should be bonded.

Thank you

RE: fluoro silicon elastomer

I don't know if it is applicable to you, but there are several RTV products (including 157), that contain acetic acid, which can be very corrosive.
For more info see AC 45-206 part1 - pages 15,85 and table 5-2
