Standard Test Methods for Volatile Content of Radiation Curable Materials

Importancia y uso:

5.1 These test methods are the procedures of choice for determining volatile content of materials designed to be cured by exposure to ultraviolet light or electron beam irradiation. These types of materials contain liquid reactants that react to become part of the film during cure, but, which under the test conditions of Test Method D2369, will be erroneously measured as volatiles. The conditions of these test methods are similar to Test Method D2369 with the inclusion of a step to cure the material prior to weight loss determination. Volatile content is determined as two separate components—processing volatiles and potential volatiles. Processing volatiles is a measure of volatile loss during the actual cure process. Potential volatiles is a measure of volatile loss that might occur during aging or under extreme storage conditions. These volatile content measurements are useful to the producer and user of a material and to environmental interests for determining emissions.
