1、Designation: C1369 07 (Reapproved 2014)Standard Specification forSecondary Edge Sealants for Structurally Glazed InsulatingGlass Units1This standard is issued under the fixed designation C1369; the number immediately following the designation indicates the year oforiginal adoption or, in the case of
2、 revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification describes the properties of cold,liquid-applied, single or multi-component,
3、chemically curing,elastomeric sealants used as the secondary seal of sealedinsulating glass units, hereinafter referred to as the “sealant”(see Fig. 1). These sealants are intended to be a structuralcomponent of sealed insulating glass (IG) units used instructural sealant glazing (hereinafter referr
4、ed to as SSG).Typical designs and considerations can be found in GuideC1249. Presently only certain silicone sealants are recognizedas having the necessary durability for use as secondary sealantin IG units in SSG applications.1.2 This specification does not describe all of the necessaryproperties o
5、f the sealant. Only those properties for which thereare ASTM test methods and industry-agreed-upon minimumacceptable test requirements are described by this specification.Additional properties will be added as ASTM test methods forthese properties become available.1.3 This specification only address

Materials and Manufacture5.1 Sealant:5.1.1 Furnish single-component sealants as a homogeneousmixture of a consistency suitable for application. Apply thesealant in stric
16、t accordance with the written recommendationsof the sealant manufacturer. The cured sealant shall be anelastomeric solid.5.1.2 Multi-component sealants shall be mixed in the cor-rect ratio4of components and delivered by appropriate equip-ment as specified by the sealant manufacturer.6. Requirements6
17、.1 The physical, mechanical, and performance propertiesof the sealant shall conform to the requirements described inTable 1.6.2 The standard substrate for this specification is clear,uncoated float glass. If metallic coated5glass substrates are tobe qualified by this specification, they shall be tes
18、ted by TestMethod C1135 as required in 8.1.6.6.3 The sealant shall be compatible with the components ofthe edge seal.3Reflective and low-emissivity metallic materials are typical coatings applied tothe glass substrate. If the coatings are edge deleted for actual production, theyshould be edge delete
19、d for use in this specification.4If the mix ratio of multi-component sealant is not within the sealant manufac-turers recommendations, the cure rate, tack free time, cohesive strength, andadhesive strength of the sealant can be adversely affected.5Metallic coatings that require a sealed air space ar

Significance and Use7.1 Not all sealants meeting this specification should bepresumed to be suitable for all applications and all substrates.This specification assists in selecting sealants that meet certainminimum standard
23、s of performance.7.2 This specification does not evaluate the adhesion of thesecondary sealant to the IG unit spacer. Adhesion of thesecondary sealant to the spacer is generally considered neces-sary for the successful performance of the IG unit edge seal.7.3 When specifying a sealant using this spe
24、cification, it isessential that the applicable type and use also be included in therequirements. This will ensure that the proper sealant isprovided for the intended use.7.4 IG units qualified by this specification shall have a lowmoisture vapor transmission sealant for a primary seal and astructura
25、l silicone sealant for a secondary seal.7.5 This specification does not address appropriate sealantstiffness since the appropriate stiffness is a function of theparticular insulating glass system in which the sealant is used(that is, varies with spacer, shape and set back, and sealantconfiguration).
26、 Test Method C1265 can assist in evaluatingthese aspects of the sealant in a particular IG system.8.
