Of course, you must make sure the compound passes any muster for conductivity, outgassing or flamability that your customer may require.
Temp is no problem. Any good epoxy would fit the bill. It depends on what I noted above and how fast you want the material to pot over ---- or working time...
This is very easy to accomplish with the use of a polyolefin primer which will raise the surface energy of the polypropylene but only for a window of time---usually 20 minutes.
Yes with the use of a primer such as a polyolefin primer. Remember, the surface energy of the silione will be raised for a window of time---usually 20 minutes and then it will dissapate.
You are working with low surface energy materials. You must prepare the substrates by raising the surface energy with a primer. Then you may find a cyanoacrylate will work depending upon the stresses, heat and chemical exposure.
Bear in mind, when using a polyolefin primer, the surface energy...
