Do it yourself

For the first time I took up the assembly of a 3D printer and faced the following problem: to assemble the extruder, you need the following, I quote:

Ceramic cement, silicon heat compound, or high-temperature muffler putty

These materials were not included in the kit. they could not be mailed. Prohibit rules.
As far as I understand, the fastening material must withstand and be a good conductor of high temperatures of 240C +. And it should also hold on well to metal (if I'm not mistaken, one of the parts is bronze) and plastic.
I can’t find in stores and google any suitable material that can be bought in Moscow.
Guys who collected 3D printers, advise what to use for this and where to buy it.

Look for KPTD-1
I say in advance, in a chip and a dip, the price is usually 2-3 times higher

Ask your auto shop for a high temperature sealant.

poxypol won't work? I, I confess, put a candle in the engine on it - I held it very well :)

For your choice:

cold welding +280С
If a completely rigid connection is not required, then you can use this sealant + 275C
Composition for repairing car exhaust systems +1000С

Ceramic cement and high-temperature muffler putty are about the same thing, muffler sealant or fireplace putty. holds up to 1100 degrees
silicon heat compound - this is an automotive sealant, red. holds up to 300 degrees, I do not advise.
In general, only the thermistor and heating resistors are poured into the hotend. I use Radial glue. Holds up to 300 degrees. Sold in syringes. Check at the checkout if it's dry. Dried out very often.
