Does anyone know what is the black rubbery glue that Intel uses to stick the IHS onto the pcb?
It's not black silicone sealant that some people recommend. I've already tried it and it's way too flexible, extremely elastic and not strong as a glue at all. After curing, I can easily slide the IHS sideways by pushing it with my finger (and I don't have to be firm). It's great for oven doors or stuff like that, but not for glueing an IHS.
The one used by Intel, even though it's rubbery, is much harder (less flexible) and much stronger as a glue (you need serious effort to cut it, or use a hammer+vice). As you know, you can't push the IHS sideways with your finger. I've delid'ed more than five i7 3770K and I know how it looks and feels. It's nothing like the super-flexible black silicone sealant.
Apart from the one used by Intel, does anyone know an equivalent that has similar properties?
