Hi,
I have the heatsink on the attached picture where have a pink sticky thermal paste and hardly dissolved with IPA. I used paint thinner to remove it. This thermal paste must be a kind like a thermal pad where don’t need replacement like the “ordinary” thermal paste. I have seen the same type of this paste at the below datasheet (figure 12). Do you know what kind of thermal paste is?

Hi @oktabitt, looking into this I’m not finding the specific paste they used in the part you referenced, as far as comparable thermal paste options in our catalog the color alone does a surprising amount in narrowing down the options for review- not very many pink thermal compounds in the list. It basically comes down to these 4 items.

I’d recommend investigating these to see if they have the traits you’re looking for.
That seems likely to be a “phase change material” as opposed to a “paste”. PCMs are essentially solid at room temperature and therefore usually sold as sheets or films, rather than as a material dispensable from a tube or syringe. Some in-stock examples can be found here.
Such materials may offer somewhat better results compared to a grease-type product if attempting to re-assemble without replacement of the interface material, but replacement is recommended.
