Abstract

The results of the study of color characteristics, surface profile and glass transition temperature of fluorepoxy (VE-46) and acrylstirol (AS-1115) coatings on the front and back surfaces of KMKU-2m.120 carbon fiber plastic exposed for 8 and 13 years in open conditions of a moderately warm climate were presented. Methods of colorimetry, profilometry and dynamic mechanical analysis were used to obtain information about the properties of coatings. Red enamel VE-46 and yellow enamel AS-1115 tuned out to be the most vulnerable to photochemical activity processes.
