The wettability of a particular solid coating, substrate or pigment on a surface is a key to its effectiveness, as wetting is important to adhesion as well as to the prevention of surface defects such as craters, dewetting and crawling. A new ASTM International standard uses contact angle measurements to determine the wettability of coatings. The new standard, D7490 , Test Method for Measurement…

By necessity, paint used for roadway applications needs to dry quickly. Some multi-component traffic paints cure in less than 10 minutes, some much faster. Because of this speed of curing, these traffic paints and other types of fast-cure (less than 10 minutes) multi-component paints cannot be tested for volatile content using procedures outlined in the ASTM International standard typically used…

Explorations into alternative forms of energy have increased interest in standards for solar energy applications. ASTM International Committee G03 on Weathering and Durability has recently approved a new standard in this area, G197 , Table for Reference Solar Spectral Distributions: Direct and Diffuse on 20° Tilted and Vertical Surfaces. ASTM G197 was developed by Subcommittee G03.09 on…
