Each of the properties listed should be considered in selecting materials for specific projects. A list of the selected properties with limiting values assigned will form a part of the product specification.
All of the properties may not be pertinent in any specific situation, and all of the tests outlined may not be required. A condition to any specification must be an evaluation of the proposed use to determine which properties may be required.
Membrane reinforcements are frequently specified and used with mastics and coatings. Service properties of such systems of finishes may be different from the unreinforced finishes; therefore, it is essential to test specimens of the reinforced system.View Less
1.1 This guide identifies properties of mastics and coating finishes characterizing their performance as finishes for thermal insulation.
1.2 These properties relate to application and service. Each property is defined, and its significance and suggested test methods are described.
1.3 The properties appear in the following order in this guide.
|Temperature and Humidity Range||6.6|
|Surface Wetting and Adhesion||6.7|
