    ASTM C1369

    Abstract

    This specification covers cold, liquid-applied, single or multi-component, chemically curing, elastomeric secondary edge sealants for sealed structurally glazed insulating glass units. Only the minimum acceptable test requirements for and the durability of these materials are described by this specification. A sealant that qualifies under this specification is classified into two types according to the number of components and into two uses according to application. Sealants should conform to the required values of extrudability, rheology, hardness, heat aging, weight loss, cracking, chalking, durability, tensile strength, and minimum 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. Scope

    1.1 This specification describes the properties of cold, liquid-applied, single or multi-component, chemically curing, elastomeric sealants used as the secondary seal of sealed insulating glass units, hereinafter referred to as the "sealant" (see Fig. 1). These sealants are intended to be a structural component of sealed insulating glass (IG) units used in structural sealant glazing (hereinafter referred to as SSG). Typical designs and considerations can be found in Guide C 1249. Presently only certain silicone sealants are recognized as having the necessary durability for use as secondary sealant in IG units in SSG applications.

    1.2 This specification does not describe all of the necessary properties of the sealant. Only those properties for which there are ASTM test methods and industry-agreed-upon minimum acceptable test requirements are described by this specification. Additional properties will be added as ASTM test methods for these properties become available.

    1.3 This specification only addresses the durability of the secondary edge sealants for structurally glazed insulating glass units. Durability of sealed insulating glass units can be found in specifications and guides that reside within ASTM Committee E06.

    1.4 The committee with jurisdiction for this standard is not aware of any comparable standard published by other organizations.

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