What is the black stuff used to coat All the BEHR (sp?) Alloy intercoolers??

You know like on my Interchargecooler thing or a normal 2 or 4WD cooler, it aint powdercoating is it?? certainly not anodised...

What benefit does it have??

Cheers

Black conducts the heat better and also makes it invisible to radar detection Thought it was just black paint?

PhilM

Just black rad paint isn't it?

Black disspates heat via radiation better than a silver one for example.

Yeah sorry I remember In A Level physics about Black disipating heat etc.... What I shouldve said was... Does it make THAT much difference, N.B. I was also often asleep in A-Level Physics

IF it is just black rad paint, where can I get some from and does it stick well ???

speak to graham @grs .. he did mine for me

Damo V

Nice one Eagle... did you have any pics??

Billabong

Ah, but did he paint it or powdercoat it?

paint it of course .. you cant powdercoat an intercooler

Billabong

Give me yours and I bet I can

ermmmmmmmmmmm


sorry mate .... but .... no ... my RS500 intercooler is in good condition

Hang on FFS! Black intercooler is bad because it absorbs more heat from the outside, but an intercooler has enough to worry about 'cos of the heat from the inside! So an good intercooler must be silver or white I guess. Black is not desirable, though the difference it makes is probably 0.1% or thereabouts

Wrong im afraid lol. Black of coures absorbs radiation - which is why it is black. BUT, when the item in question is at a hotter temperature, black will shed it's heat quicker. If you want something not to absorb heat, then it should be silver.

Black is better for heat transfer, both into and out of, so radiators should be black to work best.

MadMac

Yep a black surface is better at dissapating heat

I'm getting all mine anodized black

Ginge !

the paint on the i/c is a special paint, speak to stu at msd and he knows lot about it its not a normal matt effect paint !!!!

anodise = shiney,
shiney = not as good as matt

paint would be a lot better

Prob gonna try a bit of etch primer and straight 2k black with a matting agent, see how long it lasts

Rick

It'll last forever. My block is in 2 pac and is mint.

Ryan

i think its powedercoated.

Whenever people think powder coat, they think THICK layers.

It doesnt have to be

Damo V

Depends on the painter though ay

Alloy

Powdercoating is actually really thin!

Pace do a thing called Thermal Dispersant coating on the rad's if you ask, I'm not too sure if this a layer of some kind of black coating or not though, phone them and see.
