ORIGINAL: RoguedogI went to both websites and it turns out both company's are using the term ''Epoxy'' very loosely. Both products are in fact a type of Enamel Paint and not really Epoxy based at all as far as a thermosetting polymer. Normally, epoxy paint is composed of two parts, a resin and a hardener. Not so with these so called Epoxy Appliance paints currently being marketed by both company's<o

NOUN:
In both senses also called epoxy.

An epoxide is a ring-shaped organic compound or molecule that results from the combination of the two parts of resin and hardener. The other characteristic of an epoxy is the formation of heat while forming the ring-shaped organic compound. <o

Quote:

I agree, they are not true 2 part epoxy paints such as Klass Kote and the like. They are however one stage epoxy resin based paints meaning that they contain epoxy resins in them.

<o

></o

>The two brands of Appliance Epoxy paints we discuss here do not fall into the above category at all. <o

></o

>It does say on the Krylon website that they contain Epoxy Resins but after reviewing the MSDS sheet for the both Appliance paints the formulations are similar to their other line of paints respectively nothing referencing any of the main ingredients of epoxy like the resin Bisphenol-A type epoxy . I reviewed the MSDS sheets of both and they did not say anywhere that they contained a one stage or single stage Epoxy Resin.In fact they are claiming them to be Enamel paint.<o

></o

>Nor are there any warnings of any kind about a thermosetting re-action after being sprayed. If you want to say they form some type of polymer, I’ll agree to that but as far as a one stage epoxy resin I suspect the term Epoxy Resins is a marketing term only. Saying that they have epoxy resins sounds better than saying plastic resins. Also may really refer to the finish they exhibit, a plastic like epoxy finish, after they dry.<o

>To say that its epoxy by the way it feels is nonsense. I agree to the fact that they are very user friendly as to how they are applied but to say you can feel its epoxy is absurd. I think the feeling you were getting was from breathing in too much of the paint fumes.<o

>If you review the MSDS sheets for the Dupli-color Clear Top coat Spray paint you will see that there are several really nasty chemicals inside. The two I suspect caused your problem are Toluene and the Methyl ethyl ketone. Both are very strong solvents. As a matter of fact I’ve use MEK to melt the plastic together for evaporative cooler water distributors. Nasty stuff. I suspect it leached out some of the color of the so called Epoxy White (Enamel paint) pigments and distributed them into the clear coat.<o

Quote:

These paints contain clear coats within the can as well

<o

>What? This is just nonsense as well. How can a paint can with color pigment in it also have a clear coat in it as well? Come on dude.<o

>I realize that your ego is bruised because you asked for advice about mixing different types of paints together then chose not to follow the advice given. What’s the point of asking for advice if you’ve already made up your mind not to follow it. <o
