Protective Coatings for Outdoor LED and Painted Displays
UV Blocking, UV Resistant and Moisture Blocking Transparent Protective Coatings for Clear Preservation of Plastic, Wood, Paint and Metal:
UV and moisture blocking, transparent protective coatings are the two unique combination characteristics of SC7050-UVB and SC7130-UVB that are not found in any other sprayable, brushable coatings. These flouropolymer based coatings have now been proven to provide outstanding non-yellowing protection for the large outdoor LED display panels.
If the printed wiring board are for indoor applications and only need to protect against moisture, water and even salt fog or acid rains, AIT CC7090-E and CC7130-E will be the recommended choices of conformal coating. However, if the devices or part of the device are also exposed to the direct sun needing protection against UV enbrittling and degradation effect on the plastic parts, SC7050-UVB and SC7130-UVB are the proven choices.
UV rays from sun exposure also discolors and enbrittle the paints on outdoor exposed surfaces such as painted displays and printed advertisements. Of course, any outdoor objects that are painted and exposed to the sun will also suffer the same fate of fading colors. SC7050-UVB coating on top of the decorative or functional paints will extend the coloring for many years. SC7050-UVB besides provides transparency while blocking out harmful UV light, it also block out moisture and water penetration and thus provide additional protection to the painted surfaces.
Painted displays are normally last only one or two season and will need to be replaced or paint over when the paints or prints color are fading rapidly. For a more permanent display requirements, AIT SC7050-UVB will provide the protection against color fading and structural integrity for many years and thus reduces the costs of maintenance and replacement.
For the colorful displays and objects near the sea, SC7050-UVB transparent coating not only extend the color brilliance, they are provide corrosion and degradation protection against salt fog and salt water.
