Study on performance of high reflectance paint for building

Part3 Solar reflection after weathering test

Abstract

We calculated solar reflection of the paint to examine an effect of the high reflectance paint and mechanism by a previous report and reported that we measured a temperature change in the outdoors with various examination devices.It is often that the high reflectance paint is painted as a main use on a roof part,which deterioration generally accelerates on most rapidly among the parts of buildings and it is thought that the durability of the paint is related to the durability of the performance to block the heat.In this report,we conducted an investigation of the durability of the performance to block the heat with the high reflectance paint by a test of natural wethering test for one year and accelerated weathering test for 2000 hours.
