Description

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.

Scope

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.
