... Jointing and sealant products play an important role in maintaining the weathertightness of buildings. Despite being relatively inexpensive, in respect to the overall cost of a building, they help minimize water penetration into and air movement across the building envelope. As such, sealant...

... of the replacement granite panels, two mock-ups consisting of granite, polyurethane sealants, and silicone sealants were constructed to assess the staining potential of the sealants. The mock-ups were placed on the roof of a two-story building in Northbrook, Illinois, facing south. One of the mock-ups was oriented...

... Weathering testing of sealants and adhesives is critical to understanding how these materials will perform in outdoor environments. A wide variety of natural outdoor and accelerated weathering test standards are used to evaluate sealants’ performance in service environments. These tests can...

... Dibenzoate plasticizers are widely utilized in latex caulks because they are compatible with the polymers used in that application. Dibenzoates are also known to be used in the polymer side of two-part insulating glass polysulfide sealants. A new and promising application for dibenzoate...

... Structural sealant glazing (SSG) is an impressive technical response to the challenges of modern structural design. The evaluation of fitness for use as well as durability is a precondition for approval of SSG-façades by building authorities because of their special safety relevance. However...

... More information about the capability and especially about the durability of structural sealant glazing (SSG) systems are needed. To make a contribution to unanswered questions, a suitable system evaluation test is necessary. The basis for such a test is a load function, which accounts...

... Two sets of butt joint test specimens (ISO 8339 type) with mortar substrate (ISO 13640, Method 1) were prepared without primer using eight one-component polyurethane sealants; four of low modulus (LM) type showing a movement capability of 25 % and four of high modulus (HM) type showing...

... This paper reviews sealant weathering test methods developed during the past 40 years and highlights the fact that repeated movement cycles were shown to be important to reproduce some of the damage seen on real buildings. The studies reviewed further demonstrate that water, sunlight (especially...

... A new sealant weathering test method expands on existing test methodologies. In ASTM C719, repeated movement cycles were shown to be important to reproduce some of the damage seen on real buildings. Weathering tests done previously demonstrate that water, sunlight (especially the UV portion...

... Despite recent progress to develop a performance-based specification for bituminous sealants applied to asphalt concrete (AC) roadways and runways, a performance-based specification for cold-applied joint sealants for Portland cement concrete (PCC) aprons, taxiways, and parking areas has yet...

... while the quality and performance of elastomeric sealants used in exterior building walls have improved, the occurrence of leakage and envelope failures attributed to sealant installation has not decreased. This paper will outline, from a contractor's viewpoint, what designers need to know...

... with elastomeric sealants may temporarily facilitate runoff, at the same time restricting evaporation. Impermeable joint materials in masonry structures without overhanging roofs or other water-diversionary tactics will trap the inevitable water within the masonry units, leading to biological decay...

... Mini-specimens of silicone based construction sealant having dimensions 2.5x2.5x10-mm were subjected to cyclical movements using manually adjusted vises according to a procedure previously used to assess the performance of standard model sealant specimens. Failure probability analysis using...

... There are several completed studies of sealants weathering outdoors and in accelerated weathering machines. There is no perfect correlation but there are remarkable similarities in the results and a general correlation is possible. The general conclusion is that it takes no less than 1000 hours...

... The growth of Exterior Insulation and Finish Systems (EIFS) as a cladding system and the subsequent problems associated with the use of sealants with EIFS, has led to development of a new test method through ASTM C-24 Committee. Sealants play a synergistic role with the EIFS and their properties...
