2、 case of 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-co
3、mponent, chemically curing, elastomericsealants used as the secondary seal of sealed insulating glass units, hereinafter referred to as the “sealant” (see Fig. 1). Thesesealants are intended to be a structural component of sealed insulating glass (IG) units used in structural sealant glazing (herein
4、afterreferred to as SSG). Typical designs and considerations can be found in Guide C1249. Presently only certain silicone sealants arerecognized 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 necessa
5、ry properties of the sealant. Only those properties for which there areASTM 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 specifica

Classification of Sealants4.1 A sealant qualifying under this specification shall be classified as to type and use as foll
17、ows:4.1.1 Type SA single-component sealant.4.1.2 Type MA multi-component sealant.4.1.3 Use GA sealant that meets the requirements of this specification when tested on clear, uncoated float glass substrates.4.1.4 Use OA sealant that meets the requirements of this specification when tested on coatings
18、3 such as reflective andlow-emissivity metallic materials applied to glass substrates.5. Materials and Manufacture5.1 Sealant:5.1.1 Furnish single-component sealants as a homogeneous mixture of a consistency suitable for application. Apply the sealantin strict accordance with the written recommendat
19、ions of the sealant manufacturer. The cured sealant shall be an elastomeric solid.5.1.2 Multi-component sealants shall be mixed in the correct ratio4 of components and delivered by appropriate equipment asspecified by the sealant manufacturer.6. Requirements6.1 The physical, mechanical, and performa
20、nce properties of the sealant shall conform to the requirements described in Table1.6.2 The standard substrate for this specification is clear, uncoated float glass. If metallic coated5 glass substrates are to bequalified by this specification, they shall be tested by Test Method C1135 as required i
21、n 8.1.6.6.3 The sealant shall be compatible with the components of the edge seal.7. Significance and Use7.1 Not all sealants meeting this specification should be presumed to be suitable for all applications and all substrates. Thisspecification assists in selecting sealants that meet certain minimum
22、 standards of performance.7.2 This specification does not evaluate the adhesion of the secondary sealant to the IG unit spacer. Adhesion of the secondarysealant to the spacer is generally considered necessary for the successful performance of the IG unit edge seal.7.3 When specifying a sealant using
23、 this specification, it is essential that the applicable type and use also be included in therequirements. This will ensure that the proper sealant is provided for the intended use.7.4 IG units qualified by this specification shall have a low moisture vapor transmission sealant for a primary seal an
24、d astructural silicone sealant for a secondary seal.3 Reflective and low-emissivity metallic materials are typical coatings applied to the glass substrate. If the coatings are edge deleted for actual production, they shouldbe edge deleted for use in this specification.4 If the mix ratio of multi-com
25、ponent sealant is not within the sealant manufacturers recommendations, the cure rate, tack free time, cohesive strength, and adhesive strengthof the sealant can be adversely affected.5 Metallic coatings that require a sealed air space are typically edge deleted in regular production. They must also
26、 be edge deleted for this testing.FIG. 1 Cutaway Section of IG Unit Edge SealC1369 1927.5 This specification does not address appropriate sealant stiffness since the appropriate stiffness is a function of the particularinsulating glass system in which the sealant is used (that is, varies with spacer
27、, shape and set back, and sealant configuration). TestMethod C1265 can assist in evaluating these aspects of the sealant in a particular IG system.8.

When establishing the shelf-life,
30、 the manufacturer should also identify acceptable conditions of storage for thesealant.9.
