Abstract:
A field test and large-scale test were conducted. Coupon tests revealed reasonable durability when exposed to room temperature, immersion in water at 65 degrees and 111 degrees, air at -4 degrees, repeated freezing and thawing, outdoor elements, and fire. Thorough investigation of the adhesive after application and then again 3 1/2 years after application provides valuable information on how well the adhesive performed in an outdoor environment with intermittent stresses. The report includes organized data showing durability of the product from every application and use throughout the study period, 3 1/2 years. Detailed instructions on field application were developed and are included in this report.
