OK whats the truth?

[Mobilejay]

So I have been reading doing some research for something I am wanting to put together and am finding different "facts".



What is the temperature when nuba breaks down and melts. I have read, 139F I have also read 212F (95C) and then some others. Also 82C (179F)

So which one is it? Is it stupid high like 212F or is it closer to 100F?

I`d also like to know. If there is a definite temp then will the other ingredients in the wax cancel out the effects of whatever the high temp is?

From Carnauba: - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Carnauba:)



"melting point: 78-85 °C, among the highest of natural waxes"



That`s in it`s pure form. Putting solvents in with it will lower the melting point.

Thanks Sup

[BigJimZ28]

all auto waxes are going to have different melting temps

based on there exact make up

While it may be true, I wouldn`t believe anything from Wikipedia, any one can post any so-called "fact" they can make up!

Yeah but I took a look on different sites from Yahoo and Google and they are all giving around the same melting point.

This place: Carnauba Wax (http://www.spwax.com/spcarnau.htm) says 83 C.



This place: Carnauba wax: Encyclopedia II - Carnauba wax - Technical information (http://www.experiencefestival.com/a/Carnauba_wax_-_Technical_information/id/623060) says 78-85 C.



This place: Carnauba Wax T1 - Natural, Organic Plant Waxes - Plant Waxes for Industrial & Cosmetic Applications - Oils by Nature (http://www.oilsbynature.com/products/carnauba-wax-t1.htm) says 80-88 C.

Alot of people dis Wikipedia, and possibly with good reason, but I`ve *always* found it to be a good source of information.

What matters is how the wax handles heat once it is combined with all the other ingredients the finished product contains. I have never had a problem using carnaubas on black paint in the summer here in Dallas.

[Lumadar]

That`s pretty scary considering typical paint temperatures range from 110-170~ depending on color and time of sun exposure.

Mike Phillips over at Meguiar`s posted pics of temp readings directly from the paint surface on cars during one of their classes. Makes you wonder how long carnuba-based waxes could possibly last in hotter environments? :eek:

83 Celsius = 181 Fahrenheit -> Temperature conversion online. (http://www.convert-me.com/en/convert/temperature)

[imported_weekendwarrior]

Look at soemthing like Collinite 845. That stuff is used on power insulators. It makes me wonder what all is mixed in with it, and what its melting point is. I get good durability oout of it.

[wannafbody]

Regardless of what the wax is mixed with the wax portion will break down at the same temp. If it is mixed with high heat resistant resins then the resins won`t break down and will remain on the surface. But if I understand this correctly, from the diagrams that I`ve seen the molecules form a chain. What happens when the carnauba wax molecules break down? You end up with missing links.

[Accumulator]

But do the carnauba molecules break down in a way that`s significant once the mix had set up/cured/whatever :confused: Do the missing links *matter*? Hey, *I* don`t know...I just go by what I experience on my cars (shoulda payed closer attention in those chem classes :o ).



If there were an issue with this, I really think that ScottWax woulda noticed by now. Even when my Jag`s engine heat kills the Souveran, it`s a matter of the wax not lasting very long; it`s *NOT* like the wax gets compromised/weird/whatever. The hood gets *way* too hot to touch, you`d get a serious burn, but the Souveran doesn`t sweat/get oily/whatever, it just needs redone sooner than some other products would.



I dunno...I don`t really care if people want to go with purely synthetic products to avoid heat-related issues; I don`t have a dog in this fight. But I really think I woulda noticed some kind of problem if carnaubas were as heat-sensitive as some people make `em out to be. I`ve been using them since `76 (including years of use on black cars) and I really think I woulda noticed *something* (besides my need to rewax the Jag`s hood kinda often) by now if it were that big a problem :nixweiss



wannafbody- Heh heh, about the only time you and I ever come close to :argue is when we discuss carnaubas :D Did you ever get over to Beaverun for a track day? I did my latest training in NJ this time instead...if I do get over to Beaverun you and I gotta get together.

[wannafbody]

No, $4 gas killed the idea. Don`t get me wrong, I`ve used 845 but I also noticed that over a period of months dirt would attach itself. I`m assuming that the product was breaking down. Maybe it depends on how frequently it`s applied. The worst case for me was the water spotting on my vinyl stripes protected by 845. After about 1 1/2 years I had to remove them. I couldn`t get them clean. It`s possible that no product would have been able to protect them:nixweiss
