Existing accelerated laboratory procedures for the assessment of the adhesion of silicone sealants fail to consider the fact that the sealant/substrate interface in a building facade is continuously subjected to a combination of both mechanical and environmental stress. As a result of this, standardised test protocols lack the discrimination necessary to assess relative adhesive behaviour. A novel test procedure is offered which enables improved discrimination of the adhesive strength of the sealant/substrate system. The method is based on the simultaneous application of both mechanical and hydrothermal stress, in order to promote adhesive failure at loads below the cohesive strength of the bulk sealant.

ABSTRACT: Existing accelerated laboratory procedures for the assessment of the adhesion of silicone sealants fail to consider the fact that the sealant/substrate interface in a building facade is continuously subjected to a combination of both mechanical and environmental stress. As a result of this, standardised test protocols lack the discrimination necessary to assess relative adhesive behaviour. A novel test procedure is offered which enables improved discrimination of the adhesive strength of the sealant/substrate system. The method is based on the simultaneous application of both mechanical and hydrothermal stress, in order to promote adhesive failure at loads below the cohesive strength of the bulk sealant. A simpler version of the novel procedure allows for the screening of sealant/substrate combinations that represent potential long-term durability risks. This is achieved by the combination of hydrothermal and mechanical stress at a level close to the structural silicone design stress (0.138 MPa) applied through imposing a 12.5% strain (equal to the normal design strain in silicone sealants) together with immersion of the joint in hot water.

The Mandatory Building Inspection Scheme and Mandatory Window Inspection Scheme have been enforced in Hong Kong by the building authorities. All structural components, including structural sealants on buildings that are more than 30 years old, must be inspected and certified by a registered inspector. The Hong Kong building authorities require a safety factor of at least 5 for structural sealants, but the current test method, ASTM C1392-00, Standard Guide for Evaluating Failure of Structural Sealant Glazing, cannot help the registered inspector to determine the safety factor of the sealant on old buildings because it is not a destructive test in which the ultimate strength of the sealant can be found. To evaluate the structural performance of an aged structural sealant or to find out its safety factor, the ultimate tensile strength of the sealant must be found. The objective of this paper was to study the ultimate tensile strength of an aged structural sealant using a destructive test method. A site deglazing test and H-piece tensile test based on a modified version of ASTM C1135-05, Standard Test Method for Determining Tensile Adhesion Properties of Structural Sealants, were adopted for the evaluation process. Sealant samples were collected from four buildings with a similar age, approximately 30 years old, but the ultimate tensile strengths were found to be very different, ranging from 82.36 to 159.8 psi.

Completely revised and expanded, the Third Edition covers the numerous improvements in sealant and adhesive technology since 1984. Features the latest advances in sealants, gaskets, tapes, waterproofing membranes and silicone structural sealant glazing. Includes new chapters on insulating glass sealants, structural silicone adhesives and membrane waterproofing. Revises and supplements existing specifications with upgraded recommendations and proposed performance requirements where standards do not exist. A guideline for architectural specifications covering sealants, fire stops, membranes and coatings is included for the first time. As always, the latest ASTM Committee sealant standards are included.
