National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Determination of the Modulus of Elasticity of Structural Silicone Sealants.

PB88157458

Publication Date	1987
Personal Author	Tock, R. W.; Chew, C. H.; Minor, J. E.
Page Count	110
Abstract	An increase in the use of structurally glazed window glass systems has resulted from recognition of the properties of silicone sealants. These sealants became known as structural silicone sealants through their use as structural connections. The sealant must have resistance to oxidation and ultraviolet rays since the seal may be in full exposure to sunlight. Further, it must not deteriorate when in contact with chemicals in the air or with water. A standard design methodology would be welcomed. Although manufacturers of structural silicone sealants provide material specifications for their products, not all of the required engineering properties can be obtained from these product data sheets. The modulus of elasticity (Young's modulus) is needed; the property is relatively unknown to most users of structural silicone sealants. Definition of the engineering property as functions of temperature, elongation rate, and percent elongation is the subject of the report.
