Role of salt on adhesion of an epoxy/aluminium (oxide) interface in aqueous environments

February 16, 2014
Author(s)
Christopher C. White, Kar T. Tan, Donald L. Hunston, Justin M. Gorham, Aaron M. Forster, Vogt D. Bryan
The durability of adhesive joints in hostile environments is a major area of concern in structural adhesive bonding. Therefore, understanding the mechanics and mechanisms of degradation of adhesive joints is a key factor for more extensive use in future

An accelerated exposure and testing apparatus for building joint sealants

October 30, 2013
Author(s)
Christopher C. White, Donald L. Hunston, Kar T. Tan, John W. Hettenhouser, Jason D. Garver
The design, fabrication and implementation of a computer-controlled exposure and testing apparatus for building joint sealants are described in this paper. This apparatus is unique in its ability to independently control and monitor temperature, relative

Statistical Prediction of Sealant Modulus Change due to Outdoor Weathering

October 17, 2013
Author(s)
Christopher C. White, Kar T. Tan, Donald L. Hunston, Adam L. Pintar, James J. Filliben
Recently a statistically based model has been created to predict the change in modulus for a sealant exposed to outdoor weathering. The underlying high precision data supporting this model was obtained using the NIST SPHERE (Simulated Photo degradation by

Adhesion Society Meeting Proceedings

March 3, 2013
Author(s)
Rebecca Ploeger, Aaron M. Forster, Donald L. Hunston, Etienne de la Rie, Christopher McGlinchey
Consolidating adhesives have been used throughout the centuries for the conservation of painted cultural objects- such as paintings and polychrome sculpture- and if it were not for these adhesives, many objects may not have survived to the present day

Service Life Prediction for Sealants

August 27, 2012
Author(s)
Christopher C. White, Donald L. Hunston, Kar T. Tan
Previous industry consensus postulated that four elements of the weather: Temperature, Humidity, Ultraviolet Radiation, and Mechanical loading were responsible for the majority of the changes observed in sealants exposed to outdoor weathering. The NIST

Service Life Prediction for Sealants

September 29, 2011
Author(s)
Christopher C. White, Donald L. Hunston, Kar T. Tan, James J. Filliben
Previous industry consensus postulated that four elements of the weather: Temperature, Humidity, Ultraviolet Radiation, and Mechanical loading were responsible for the majority of the changes observed in sealants exposed to outdoor weathering. The NIST

LABORATORY ACCELERATED AND NATURAL WEATHERING OF STYRENE-ETHYLENE-BUTADIENE-STYRENE (SEBS) BLOCK COPOLYMER: ACCELERATION AND CORRELATION

March 23, 2011
Author(s)
Kar T. Tan, Christopher C. White, David J. Benatti, Deborah S. Jacobs, Donald L. Hunston
Indoor accelerated and outdoor field weathering of styrene-ethylene-butadiene-styrene block copolymer have been studied by Fourier transform infrared (FTIR) spectroscopy. In the indoor accelerated experiments, specimens are exposed to ultraviolet-visible

The Role of Service Life Prediction In Sustainability Determinations

February 14, 2011
Author(s)
Christopher C. White, Kar T. Tan, Donald L. Hunston
Sustainability calculations are based on assumptions about the energy required to produce, transport place in-service items. A critical component of these calculations is the expected service life of the material, component or system. Estimates of the

AN ADHESION TEST METHOD FOR SPRAY-APPLIED FIRE-RESISTIVE MATERIALS

June 21, 2010
Author(s)
Kar T. Tan, Christopher C. White, Donald L. Hunston
Adhesion of spray-applied fire-resistive materials (SFRMs) to steel structures is critical in enabling the capacity of a building to remain functional for a specific length of time during a fire for life safety and fire department assess. Empirical tests
