General Comments
The history of field performance of Kleer™ has demonstrated excellent resistance to weather in exterior applications under varied environmental conditions. The ingredients comprising Kleer™ are commonly found in exterior vinyl sidings and window components. Accelerated exposure to UV testing shows no yellowing of the product, in fact Kleer™ actually gets whiter with exposure to UV rays for the first seven to ten years. Additional testing is ongoing to accurately determine the long term environmental effects on Kleer™.
