oxidation and UV degradation due to their antioxidant properties.18 Besides wood applications, studies have reported that tannins may be used as additives to protect biodegradable polymers against UV degrada-tion.19 Some researchers have also reported that applying a waterborne acrylic coating containing bark Gamvar does not protect against UV light exposure and does not contain Ultraviolet Light Filters and Stabilizers (UVLS) for protection against the harmful effects of ultraviolet radiation. If one paints with lightfast colors, UV light should be of no concern. PPS has proven to be a dependable and effective UV protection material in everything from automotive parts to electrical components. Acrylic. Acrylic is a type of plastic that’s great for outdoor use because it’s resistant to UV radiation from the sun. Acrylic has a high percentage of a chemical called MMA, which absorbs UV radiation.
