No single test can indicate the longevity of an adhesive and the cured adhesive bonds,but several test methods can be used to obtain a broad picture of the magnitude of their longevity, at least compared to adhesives with proven longevity. EPI adhesives have been evaluated for durability and permanence using standard test methods. Test results indicate that the EPI adhesives are not sensitive to chemical characteristics of wood, are resistant to the swelling and shrinking stress of wood, and provide excellent durability and permanence. The result of these tests indicate that bonds formed with EPI adhesives will provide a long service life when exposed to a large number of environmental conditions. Twenty-five years ago EPI adhesives had no performance history. Today, many composites laminated with EPI adhesives are in service in environmental conditions ranging from the North Slope of Alaska to the heat and humidity of the Persian Gulf. Although twenty-five years is not a long time when considering the life of a structure or when considering the documented performance of a competitive adhesive, EPI adhesives are compiling an outstanding performance history. EPI adhesives are providing excellent longevity under a wide variety of end use conditions and tests to meet the requirements of a changing market where quality is the primary criteria.
