New Standard Measures Water and Volatiles

Finding a way to accurately measure the water and volatile content of high baked phenolic coatings has led to the development of a new ASTM International standard, D7245, Test Method for Measuring Total Water and Volatiles in Liquid Coatings Which Produce Cure Water Upon Heating. D7245 was developed by Subcommittee D01.21 on Chemical Analysis of Paints and Paint Materials, part of ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications.

Total water content and volatile content results obtained with D7245 are allowable when using Practice D3960, Practice for Determining Volatile Organic Compound (VOC) Content of Paints and Related Coatings, to determine VOC.

Regulatory agencies as well as manufacturers of phenolic coatings will find D7245 useful. “Since it determines water and volatiles as one test, it is possible to use this method on other coating species as well, but testing will need to be done to determine applicability,” says Steve Brunner, technical director, Heresite Protective Coatings.
