EFFECT OF EXPOSURE ANGLE ON THE ATMOSPHERIC PERFORMANCE OF COATINGS. 1. RESULTS OF TWO-YEAR EXPOSURES

Abstract

In tropical locations, the solar radiation received by a test panel can be considerably increased by changing the exposure angle from 45 degrees to the angle of the latitude. Results of two-year exposures at 45 degrees and at 9 degrees at Kwajalein, Marshall Islands, of scribed and unscribed panels coated with zinc inorganic silicates and organic topcoat systems are compared. The 9 degrees exposure may be more severe as judged from the protective properties of the coatings, but the results are not conclusive over this limited period of time.
