    Abstract

    To demonstrate the suitability of high performance acrylic sealants to low rise industrial construction applications, a laboratory prepared high performance acrylic sealant was compared to a commonly used, commercially available two part polyurethane sealant. The centerpiece of this comparison is an exterior exposure in El Paso, TX, in which the two sealants were professionally installed in alternating joints around the perimeter of a tilt-up warehouse. The sealants were also subjected to a battery of laboratory tests, including tensile testing, sealant specification testing, paintability, and accelerated weathering in both xenon arc and fluorescent UV devices. The 3 year El Paso exposure results, in combination with the laboratory, weathering, and application test results, demonstrate the performance advantages of the high performance acrylic sealant and highlight its inherent suitability for use in low rise industrial applications such as tilt-up warehouses.
