Standard Specification for Aluminum Pigmented Emulsified Asphalt Used as a Protective Coating for Roofing (Withdrawn 2011)

Abstract

This specification covers aluminum pigmented emulsified asphalt suitable for application as a protective coating for built-up roofs and other exposed surfaces by brush, roller, or spray application. The surfaces to which this product is applied are expected to have positive drainage as the coating is not anticipated for use where ponding conditions exist. The product is suitable for use on sheet metal and smooth or granule surfaced emulsion, conventional BUR, and modified bitumen systems. Three types aluminum pigmented emulsified asphalt are covered: type I non-fibered - containing no fiber, type II fibered - containing asbestos fiber, and type III - containing no asbestos fiber. The consistency, residue by evaporation, water content, hydrogen gas generation, and accelerated weathering shall be tested to meet the requirements prescribed.

Scope

1.1 This specification covers aluminum pigmented emulsified asphalt suitable for application as a protective coating for built-up roofs and other exposed surfaces by brush, roller, or spray application. The surfaces to which this product is applied are expected to have positive drainage as the coating is not anticipated for use where ponding conditions exist. The product is suitable for use on sheet metal, and smooth or granule surfaced emulsion, conventional BUR, and modified bitumen systems.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 The user is cautioned that aluminum pigmented emulsified asphalt may generate a reaction resulting in the evolution of hydrogen gas. Use caution when opening containers.

1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
