Thermal expansion coefficients of cured Belzona 1111 and 1511?

[ptuomov]

Anyone know what the thermal expansion coefficients of cured Belzona 1111 and Belzona 1511 HT are?

I've used 1111 many times and doubt there's much difference in TE between the two considering the metallic alloy frit is the same. Probably just the difference in resin temp range capability. Maybe just call and ask them?

Any time I have used epoxy or the like I do test pieces, heat them in the oven alone and on a surface similar to what I need it for as well as expose it the the fuel or chemical it has to deal with to see how it holds up.

31.7 ppm/degree C for Belzona 1111.

For Belzona 1511 it appears that you will need to contact the company. A good likelihood is that you will be told to test its suitability for your application which would be normal engineering practice.

I have emailed them, but they haven't gotten back to me yet. I asked them for the linear coefficients of thermal expansion. I also asked them to what extent those can be manipulated by adding either steel or aluminum grains into the compound. The third question was how their products react to GL 5 gearbox oil.

It makes sense to test the actual compounds before use, but it also makes sense to ask around and narrow the options before doing any testing.
