Is there a way to make paint more resistant to heat
Q. Gentlemen, is there some additive that I can add to a paint to make it heat resistant. I am thinking in terms of making a paint heat resistant enough to paint automobile engines?
If I use regular paint it scorches.
Thanx Bill.

A. Try searching on line for High Temp Paints or stoving enamels. James Watts- Navarre, Florida 2004 2004 A. Hi William Why in the heck don't you go to GOOGLE and just type in those words ? There seems to be quite a few options on hi temp auto paints.... and you should get more info than hitting on finishing.com. OK?

A. That's probably exactly what he did, Freeman, and his google search brought him here to the home page of the finishing industry. Please don't tell our hard-won & greatly appreciated visitors to go away!
But I fear that the answer is that there is no "additive" that you can put into a low temperature paint to make it a high temperature paint
[affil links] because whatever was in the paint which could not withstand high temperature will remain unable to do so despite the temperature resistance of those additives.
There are many high temperature engine paints, William, including products available from Eastwood, and high temperature paint
[affil links].

Q. Hi friends, what's the key or actual ingredient(s) that makes a paint heat/cold resistant, I am particularly interested in exterior/interior paints for homes here in the tropics where houses become very hot at night during the dry season. Thanks. Tobias.

A. Hi Tobias. The principal ingredient is white pigment in the roof shingles or, better, white roof paint. White metal roofs not only absorb much less heat in the daytime, they also more effectively radiate heat to the sky at night. Good night.

What you're seeking is what is got popular in the last few years, solar reluctance or SR compliance. It's not so much special pigments as much as restrictions on the type and amount of pigment.
We are starting to do a lot of roofing paints and compliance has gotten real popular.

Q. Hi Sir ! I want to know about the different resins which we can use for the conversion of simple paint to heat resistant paint.

A. Hi Adnan. I believe that most high temperature paints try to substitute ceramic grit particles in place of resins. But paint formulation is a whole science discipline, not something that can be covered in a one-paragraph public forum response :-)

A. If you take your current resin, most commonly a polyester you incorporate silicon to make a silicone modified polyester.It must be done chemically not just added as in a mixture.
The other method is using Siloxanes which is a carbonless resin using repeated Si-O-Si bonds.

Q. Hi Sir,
Actually I want to prepare the heat resistant paint which is used on wall and roofs of the buildings.

A. Hi again, Adnan. I think we're having a little semantics/language difficulty. You seem not to be speaking of paint which can withstand high temperatures (like on an automobile engine), but paint which helps buildings stay cool, sometimes called 'heat reflective' paint. I think if you google "heat reflective paint" rather than 'heat resistant paint' you will easily find all the info you seek. Good luck!

A. It appears Adnan is referring to solar reflective coatings, something that just recently got popular in the southern United States for roofing.
We are producing some roofing products which are required to be SR compliant.
