I found this... thought it might help (look on the left under Web Links to find the original source page from EpoxyProducts.com):
"Epoxies yellow, chalk (or more commonly least lose their gloss), in direct sunlight (UV). The yellowing can be a real problem. For pigmented epoxies select colors that are dark or contain a lot of yellow (such as green). Even clear epoxies will yellow and cloud up. Often epoxies are topcoated with latex or urethanes that will retain their color and attractive gloss. This is particularly true if color coding or matching company colors is important.
There are special epoxy formulations that have increased chemical resistance, increased temperature resistance, the ability to be applied underwater, and enhance resistance to yellowing and UV damage.
Another clue of a cheap epoxy is if it requires haz-mat shipping. Generally the better resin systems can be shipped non-haz-mat. The exceptions are special high temperature and/or more UV resistant epoxies, which often require haz-mat shipping."
I also found this at E-poxy.com (again, link on the left):
"The primary disadvantage common to most epoxy systems is poor UV resistance. UV light can lead to chalking (yellowing) and loss of gloss. Although the strength of the epoxy will not be compromised, the material is no longer aesthetically pleasing."

What is an epoxy?
Epoxy in chemistry means a compound which contains a three membered ring of atoms, two carbons and an oxygen. This is not a very stable arrangement because the bonds are strained, so as soon as something attacks them they tend to react with themselves very quickly to form giant cross linked structures called epoxy resins, which tend to be much harder than the starting material. They find applications as glues and inert coatings amongst other things. In general usage epoxy refers to the resins.
Can you apply an epoxy coating over an existing epoxy coating?
Yes. Because a chemical bond is no longer possible because the epoxy coating has dried, a mechanical bond is required. This merely means that the cured epoxy must be lightly sanded before applying the next layer: the first coat should have a matt, nearly white finish.
What are the benefits of epoxy floors over hardwood floors?
Epoxy floors are very strong and durable, a well installed epoxy floor can last up to 25 years. They are also scratch resistant and are ideal for areas with heavy traffic
What is epoxy resins in briefly?
Epoxy resins are advanced thermosetting resins used in FRP composites. Epoxy equivalent of an epoxy sample is determined by a standard titration method [6] using hydrogen bromide solution in acetic acid.
Can you mix epoxy seal krete with patio paint?
No, Seal-Krete Epoxy-Seal is an acrylic-epoxy blend. By mixing 2 unlike resins (patio paint and Epoxy-Seal) the hard Epoxy-Seal acrylic-epoxy resins would become weak resulting in a coating failure.

What kind of paint is used for striping airport and helicopter landings?
I recommend a good epoxy paint with the Uv resistant seeler.
What is the solvent for epoxy phenolic resins?
acetone

What is epoxy mortar?
Epoxy resins are used with aggregate (silica sand) to produce epoxy mortar or epoxy concrete, which is used for structural repairs of concrete.

Will epoxy resins withstand the temperature of boiling water?
In general, no.
What is aliphatic epoxy?
Aliphatics are two-part urethanes that are extremely durable, highly resistant to UV degradation (unlike an epoxy) and very color stabile. They are best used for exterior applications where a long-lasting and protective finish are desired.
Is there need for more adhesives?
yes because synthetic adhesives such as glue and epoxy resins are used in large scale industrial applications. adhesives are used for dams bridgesthermal power stations are coted with epoxy resins. modern air craft and auto mobile use epoxy resins adhesives for assembling saving money and reducing weight. so there is a need for mor adhesives
