This specification describes the properties of cold liquid applied, single-component or multicomponent, chemically curing elastomeric structural silicone sealants herein referred to as the sealant. These sealants are intended to structurally adhere components of structural sealant glazing systems. Sealants shall be classified as to types and uses: Type S; Type M; Use G; and Use O. The physical, mechanical, and performance properties of the sealant shall conform to the requirements described. The following test methods shall be performed: rheological properties; extrudability; hardness; heat aging; tack-free time; tensile adhesion; and shelf life.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification describes the properties of cold liquid applied, single-component or multicomponent, chemically curing elastomeric structural silicone sealants herein referred to as the sealant. These sealants are intended to structurally adhere components of structural sealant glazing systems.
1.2 Only those properties for which there are industry-agreed-upon minimum acceptable requirements, as determined by available ASTM test methods, are described in this specification. Additional properties may be added as ASTM test methods for those properties become available.
1.3 The values stated in metric (SI) units are to be regarded as the standard. The values in parentheses are for information only.
1.4 Committee C24, with jurisdiction over this specification, is aware of two comparable standards by other organizations: ETAG No. 002 and the Chinese national standard GB16776.
