1. Service Life Prediction for Sealants
Published: 8/27/2012
Authors: Christopher C White, Donald Lee Hunston, Kar Tean Tan
Abstract: 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 N ...

2. A systematic approach to the study of accelerated weathering in building joint sealants
Published: 5/1/2012
Authors: Christopher C White, Donald Lee Hunston, Kar Tean Tan, James J Filliben
Abstract: An accurate service life prediction model is urgently needed for building joint sealants to reduce the enormous cost associated with long-term field weathering. A stepping stone to the success of this effort is the precise control of environmental va ...

3. Transitory Temperatures of Organic-Film Coated Specimens under Outdoor Exposure
Published: 3/2/2012
Authors: William C. Thomas, Christopher C White, Walter Eric Byrd
Abstract: A mathematical model is presented and validated for predicting the temperature of thin polymeric films bonded to substrate materials. The National Institute of Standards and Technology provided specimen temperature and simultaneous weather data for t ...

4. A test method for monitoring changes during durability tests on building joint sealants
Published: 2/8/2012
Authors: Christopher C White, Donald Lee Hunston, Kar Tean Tan
Abstract: The durability of building joint sealants is generally assessed using a descriptive methodology involving visual inspection for defects. It is widely known that this methodology has many inherent limitations and is only qualitative in nature. A new ...

6. LABORATORY ACCELERATED AND NATURAL WEATHERING OF STYRENE-ETHYLENE-BUTADIENE-STYRENE (SEBS) BLOCK COPOLYMER: ACCELERATION AND CORRELATION
Published: 3/23/2011
Authors: Kar Tean Tan, Christopher C White, David J. Benatti, Deborah L Stanley, Donald Lee Hunston
Abstract: 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-vis ...

7. Summer Undergraduate Research Fellowships (SURF) at the National Institute of Standards and Technology
Published: 3/15/2011
Authors: Joseph J Kopanski, Richard L Steiner, Lisa Jean Fronczek, Christopher C White, Chiara F Ferraris
Abstract: We recruit students from underrepresented groups and at Colleges and Universities with limited on-campus opportunities for research experience. We strive to provide the highest quality and challenging undergraduate research experience by involving st ...

8. Design, Fabrication and Implementation of Thermally-Driven Outdoor Testing Devices for Building Joint Sealants
Published: 2/23/2011
Authors: Christopher C White, Kar Tean Tan, Emmett P O'Brien, Donald Lee Hunston, R. S. Williams
Abstract: The paper describes the development, implementation and testing of two thermally driven outdoor exposure instruments. These devices are unique in their ability to impose thermally driven strain while monitoring the resulting stress and displacement f ...

9. The Role of Service Life Prediction In Sustainability Determinations
Published: 2/14/2011
Authors: Christopher C White, Kar Tean Tan, Donald Lee Hunston
Abstract: 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 t ...

10. Studies on the Effect of Movement During the Cure on the Mechanical Properties of Building Joint Sealant
Published: 9/10/2010
Authors: Christopher C White, Donald Lee Hunston, Sam Williams
Abstract: A novel sealant-testing device was used to continuously monitor the mechanical properties of a one part silicone sealant for movement cycles initiated from 10 h to 168 h after sample creation. These cure times fall between the proposed RILEM TC 139 t ...
