Die Annotation des Normtextes ASTM D6694/D6694M-25 :

This specification covers a liquid-applied solvent dispersed elastomeric coating used as a roofing membrane for spray polyurethane foam (SPF) insulation whose principal polymer in the dispersion contains more than 95 % silicone. The product, as manufactured, shall be in liquid form for application to SPF surfaces by brushing, squeegeeing, rolling, or spraying. The product shall be composed of dispersion containing as the principal polymer more than 95 % silicone polymers to which various pigments and other additives have been added to give the required physical properties. Liquid properties like viscosity, volume solids, and weight solids shall be determined after conducting different tests. Physical properties of cured silicone coating like elongation, tensile strength, permeance, accelerated weathering, adhesion, tear resistance, and low-temperature flexibility shall be determined after a series of tests.
