What is the specific property of epoxy paint ?

hiya again armando,





just like your other question concerning enamels, this is kind of a broad question...





epoxy is a specific type of paint resin - usually (not always) this resin is of a urea-formaldehyde composition and requires a catalyst (chemical cross-linking) to cure. epoxy products are very tough and durable coatings for use in extreme environments. once cured, they are resistant to many chemicals (solvents, acids, caustics) and are generally very abrasion and moisture resistant.





the typical drawbacks of these coatings are they usually require mixing mutliple components - then, once mixed you have only a limited amount of time to work with the product...they are relatively expensive when compared to more conventional single component coatings...and while they can be used functionally in exterior applications, they will chalk and fade freely when in contact with direct UV light (sunlight)...





epoxies MAY be in bakable powder form (as can alkyds, acrylics, and other types of resins) but they are commonly available in solvent or water borne offerings.





once again, i hope this info is helpful - good luck.





ricWhat is the specific property of epoxy paint ?
Epoxy paint is sometimes known as powder coating. Raw epoxy paint comes in a powder form which is applied electrostatically (sticks with static) to bare metals before being baked at high temperature.





Because there is no solvent (paint thinner) involved, the process is environment-friendly (very low air pollution) and resulting coating is much stronger than those achieve by regular paint job. A drawback of epoxy paint is that it usually needs to baked at high temperature.
