UV and High Humidity exposure quickly degrades most materials
UV energy causes direct molecular fracturing of plastic-based paints and structures. The following is a mapping of UV intensity of earth by ESA (European NASA).
ZONE experiences the strongest sun exposure and UV intensity. While ZONE 1 may be exposed to the most extreme UV intensity and high temperatures, temperature swings are relatively minor. ZONE 2 is exposed to high but not extreme UV intensity and relatively mild temperature, however, they are also areas that must tolerate more temperature swings that can cause paints and other materials to crack. Thus the combined effect of moisture and UV may be even more deteriorating. In some of the industrial developed areas, acid rain effects are particularly damaging to painted metal structures.
The ability of different types of plastic materials such as PVC (commonly known as vinyl), PET (polyester), acrylics (plexiglass), polycarbonates, wood (celluloid), paints (mostly acrylic based) etc. to withstand UV damages depends on its molecular structure or the binding energy of the molecular structure. The above listed materials' molecular binding energies are lower than UV and thus are more susceptible to degradation. Highly fluorinated plastics such as Teflon, PVDF and their variations with higher fluorination have been proven scientifically and in practice to survive intensive UV exposure to provide protection for over 30 years. In addition to withstanding UV's damaging effects, its tighter molecular binding is also effective in blocking moisture, sulfur, nitric, and carbon-based acidic gases to provide additional protection against the combination of damaging elements.
Currently, painted structures, graphics and signs using vinyl or PET laminates that are embedded with UV blocking elements last 6-12 years on vertical surfaces and less than 6 years on horizontal surfaces even in ZONE 2 weather and sun.
Painted, Laminated Signs and Structural Protection
Graphics and signs using vinyl or PET laminates and paints that is embedded with UV blocking elements last 6-12 years on vertical surfaces and less than 6 years on horizontal surfaces even in ZONE 2 weather and sun.
Over time the colors of the sign facing will fade—especially for signs facing south towards the sun—reducing the contrast level between the legend and the background, and the sheeting’s retro-reflectivity properties will diminish, such that the sign can no longer be seen and read by the driver from an adequate distance. Under either condition the sign has reached its service life and should be replaced.
New signs are manufactured to be more reflective and brighter than older versions. Still, they only last about 15 years. Sunlight causes them to fade, so states constantly have to replace signs that reach their lifespan. For any states in US, typically close to 400,000 to 600,000 signs are used and maintained. Average States in US will have to replace more than 30,000 signs if one were to replaced them every 15 years.
With average cost of installation or replacements of well above US$250 each, with the ability of the FLUORSEAL® to extend the life well beyond 50 years, the saving can be more than tens of millions of dollars for a typical State.
Beyond the traffic and road sign that mostly use aluminum backing and structure that last to average of 15 years or less, the signs for tourists and attractions are even lesser protected and are typically faded and degraded in 3-12 years depending on the weather and UV zones that these structures and signed are erected. These signs are not only functional but also supposedly aesthetic and thus color fading is highly undesirable. With the ability of the FLUORSEAL® to extend the life well beyond 50 years, the costs of replacement and repairs can also be drastically reduced.
Even with a very thin coating of 10-20 micron thick, FLUOROSEAL® transparent UV protective coatings have been proven effective against high to extreme UV intensity and in blocking moisture and corrosive gases from damaging the aluminum signs and steel structures. The built-in molecular flexibility in the coating is engineered and proven to extend the life of the aluminum-based signs and steel structure in cold weather. Along with its resistant and ability to block UV penetration, FLUOROSEAL® coatings have been proven to provide effective protection even in extreme temperature swing in ZONE 2 and 3. In practice, FLUOROSEAL® coatings have been proven to perform as protective coating in outer space satellites where extreme cold to extreme hot applications.
FLUOROSEAL® transparent UV protective coatings are compatible with almost all acrylic, polyurethane, epoxy, FEVE and PVDF-based paints and stains and can be applied directly in achieving the protections.
Cedar Wood Sidings and Wood Structural Signs Protection
Cedar sidings while naturally resistant to insects such as ants, termites, and mice, they must be properly maintained at all times to reach its maximum lifespan, with many planks needing to be replaced after just 10 to 15 years, and even well-maintained cedar siding may only last around 20 to 30 years in some climates. Re-siding your home can be a considerable expense, and needing to redo sections every 10 to 15 years and replace the entire facade every 20 years can be a serious drawback for many homeowners
Cedar even when properly stained and painted wood structures are highly susceptible to color degradation under rains and sun even in ZONE 3 weather. FLUOROSEAL® transparent UV protective coating from AIT with its high fluorination molecular structure have been proven to block UV, rain and moisture including salt spray to provide structural integrity and virgin wood and paint color beyond 50 years even under direct sun in ZONE 1 UV intensity and weather.
Even with a very thin coating of 10-20 micron thick, the built-in molecular flexibility engineered to extend the life of these wooded structure and signs in cold weather with high UV intensity have been proven to provide effective protection even in extreme temperature swing in ZONE 2.
