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."
Epoxy resins that are specifically formulated with UV inhibitors or stabilizers are UV resistant. These additives help to protect the resin from yellowing or degrading when exposed to sunlight. It's important to check product specifications or consult with the manufacturer to ensure the epoxy resin is suitable for UV exposure.

Is phenolic UV resistant?
Phenolic resins are generally not very UV resistant and can degrade when exposed to sunlight, which can lead to discoloration, embrittlement, and loss of properties. To enhance UV resistance, additives or coatings can be used to protect phenolic materials from UV radiation.
What is a non thermoplastic?
A non-thermoplastic material is one that does not soften or flow when exposed to heat and instead undergoes a permanent chemical change. Examples include thermosetting plastics like epoxy resins or phenolic resins, which form irreversible chemical bonds when heated and cooled, making them resistant to high temperatures.
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 are 3 types of thermosetting?
Hi you suck so go away you're in school.
What is an epoxy?
Epoxy is a type of adhesive that is created by mixing resin with a hardener. Once mixed, it forms a strong and durable bond that can be used for a variety of applications, such as repairing cracks, filling gaps, or bonding materials together. Epoxy is known for its high strength, versatility, and resistance to chemicals and heat.
Is phenolic UV resistant?
Phenolic resins are generally not very UV resistant and can degrade when exposed to sunlight, which can lead to discoloration, embrittlement, and loss of properties. To enhance UV resistance, additives or coatings can be used to protect phenolic materials from UV radiation.
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. 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 has the author William N Bowie written?
William N. Bowie has written: 'Epoxy resins: market survey and users' reference' -- subject(s): Epoxy resins
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.
What has the author A F Yee written?
A. F Yee has written: 'Toughening mechanism in elastomer-- modified epoxy resins-- part 1' -- subject(s): Elastomers, Epoxy resins
What is the solvent for epoxy phenolic resins?
The solvent commonly used for epoxy phenolic resins is a mixture of aromatic hydrocarbons, such as xylene or toluene. These solvents help to dissolve the resins and are typically used for cleaning equipment or thinning the resin for application.
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.
What is a non thermoplastic?
A non-thermoplastic material is one that does not soften or flow when exposed to heat and instead undergoes a permanent chemical change. Examples include thermosetting plastics like epoxy resins or phenolic resins, which form irreversible chemical bonds when heated and cooled, making them resistant to high temperatures.
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
