FEVE resins exhibit little to no absorption in the UVA and UVB range. The key to formulating durable coatings with FEVE resins is to protect the components that are sensitive to these wavelength ranges, i.e. organic pigments, titanium dioxide, certain resin chemistries. It is recommended that triazine type UV absorbers and hindered amine light stabilizers (HALS) be used in coatings with FEVE res...

How Much Prep Is Needed Before Applying Over Previous Coatings? Can They Be Applied Over Rust?
If the previous coating was not high in silicone content, then power washing to remove dirt and any mold is best. If there is silicone content, sand blasting may be needed to rough up the surface to provide for optimal adhesion. It is never recommended to coat over rust. Rust on the surface will prevent proper adhesion allowing an avenue for moisture intrusion. This will propagate the rust...
What Do We Need to Look For At Coatings of Aluminum Elements That Will Prevent Corrosion?
Aluminum is protected from corrosion in large part by the thin oxide layer that forms on it or it is pretreated. However, pitting corrosion and localized corrosion can occur (typically seen in alloys of aluminum). In order to protect against this it is important to use a system with good adhesion to the aluminum substrate. Typically this will require the use of some type of primer or pretrea...
