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…

When fasteners penetrate roofing or waterproofing products as a planned part of installation, it is expected in some cases that the product will resist water migration at the point of penetration. A new ASTM International standard, D7349 , Test Method for Determining the Capability of Roofing and Waterproofing Materials to Seal Around Fasteners, addresses this situation. ASTM D7349 was developed…

Modified bitumen products have been in use since the mid-1970s, and represent a substantial percentage of the commercial asphalt roofs installed throughout North America. A new ASTM International standard addresses the use of cold process adhesives in modified bitumen roofing systems. ASTM D7379 , Test Methods for Strength of Modified Bitumen Sheet Material Laps Using Cold Process Adhesive, was…
