THE EVALUATION OF PAINT PERFORMANCE FOR EXTERIOR APPLICATIONS IN SINGAPORE TROPICAL ENVIRONMENT

Two water-base paints, a regular non-algae and an algae resistant emul sion for decorative purposes, were exposed to artificial, i.e. acceler ated, and natural weathering tests and the deterioration compared to t hat for similar paint applied to exterior walls on multi-unit building s in Singapore. The artificial weathering test was found not to provid e a good representation of actual performance since it only monitors t he deterioration due to chemical weathering and not that due to mechan ical or biological weathering. The rate of deterioration of paint expo sed in natural weathering tests in an industrial region in Singapore w as faster than that for paint exposed in-service on multi-unit housing situated in industrial, central or coastal regions in Singapore.
