Copper reacts with aluminium accelerating its oxidisation.I used syringes of the copper thermal paste very easy, not quite as good thermal conductivity as the GD900 but more than good enough for the job. Anything is better than what Dometic use.

Its just the colour of it, its a thermal paste for use with aluminium heat sinks.Copper reacts with aluminium accelerating its oxidisation.

Those mastic based ones are rubbish they dry out after a few years they are also too thick and if you apply them too thickly they make the heat transfer worse. The one Dometic use is awful that is why we are all having to replace it.So looking to get proper thermal mastic that used in the refrigeration industry as I didn’t fancy using computer based products with metals that will react with the aluminium and accelerate it’s oxidisation. They also seemed a bit thin in consistency and maybe continue to creep (run).
Not an easy product to find unless your in America, DeVan 310 or similar is used by Norcold Dometic Electrolux etc.
Mobile RV maintenance seemed to be the only company selling online in uk @ £42.
But managed to find another product in the Uk Keil Q771000 same mastic cartridge size and maybe more than I need?
I’ve sourced it from a company called Die-Pat in the UK at £32 inc postage.
Although not cheap it would probably do several fridge freezers from the one cartridge, so would be more cost effective if shared etc. I will see what’s left once both finned panels are done in my RMDT 8501.
Thermal Mastic Heat Transfer Compound - 10.3oz (305ml) tube cartridge
Description: 10.3oz (305ml) tube cartridge Replaces solder for heat transmission - Stable at all working temperatures - Does not harden or lose adhesion at -50°F (-45°C) - Flash point 450oF (232°C) - Thermal mastic can be used wherever rapid transmission is desired between coils and liners...www.die-pat.co.uk

This product is from commercial fridge industry, not from dometic.Those mastic based ones are rubbish they dry out after a few years they are also too thick and if you apply them too thickly they make the heat transfer worse. The one Dometic use is awful that is why we are all having to replace it.
The ones for the electronic/computer industry are far superior have far better heat transfer properties, thinner so actually easier to apply and they are fit and forget as they don't degrade like the mastic ones.

GD900 is £5+ for 30g it would be £50+ for same quantityFor the extra you will gain for the extra money you spend on thermal paste you have highlighted does not add up and I feel that you are maybe over thinking the task.
Go by what other Funsters have done and the results of what they have used.
The GD900 thermal paste I and other Funsters have used is effective and a is sensable price.
Why did you put a link to a Dometic product then?This product is from commercial fridge industry, not from dometic.
Maybe because I've spent nearly all my working life in the electronics industry.How do you know that these CPU products won’t dry out and corrode over time it’s not like you have a long term test to rely on.

You are comparing good quality thermal past with crap mastic.GD900 is £5+ for 30g it would be £50+ for same quantity

I didn’t link a dometic product ???Why did you put a link to a Dometic product then?
Maybe because I've spent nearly all my working life in the electronics industry.
But the thermal paste isn’t designed to be in the fridge or freezer environment.You are comparing good quality thermal past with crap mastic.

It's in your post#153I didn’t link a dometic product ???
All pastes have a drop in performance and shelf life, the CPU pastes are no different and most of these say 2yrs?It's in your post#153
There are enough posts on the forum about the paste used by the manufacturers drying out and becoming useless with fridges not working.
The stuff used in the refrigeration industry is very much cost oriented that why it is a fraction of the cost of a good quality thermal paste that the electronics industry uses.

ExactlyI've had enough of wasting my breath, you do what you feel is best for you.
Exactly
You chose to rain on my parade you could have saved you so called breath ages ago.

The photo in #153 is a Dometic product.Show me a link to a Dometic product ?
The link is to a product Keil Q771000
The information sheet on the application of mastic is Dometic literature
I asked nothing, I merely put a post about sourcing thermal mastic in the uk, it was you that said I was doing it wrong, and now your gaslighting. I just choose to think that the manufacturers normally know a thing or two about there industry. Easy as that.What a pleasant soul aren't you, you asked the question and didn't get answer you wanted or agreeing with you.
