Degradation Models for Ten-year Weathering of Architectural Coatings

Nobuhito Hirata; Norimoto Kashino; Takashi Tomiita

abstract An outdoor exposure-testing program for architectural coatings was conducted in Tsukuba from 1987-1997. Observed gross retention of samples set horizontally, 5-deg. south and 30-deg. south was on average severer than that of 90-deg. south, while the conditions of 90-deg. north are more moderate. The lightness of white samples decreased during the early part of the first year and was almost constant, thereafter. Delta L* of 90-deg. south and 90-deg. north is smaller than that of horizontal, 5-deg. south and 30-deg. south. Koike and Tanaka′s equation is a more appropriate analytical method regarding the weatherability of exposed paints and coatings than the conventional system, which uses solar UV.
