As the tempera- <br />ture of the base material increases, the bond strength <br />of the anchor will decrease. Typical performance of <br />the Power-Bond adhesive mortar at elevated base <br />material temperatures is shown below. The values are <br />based on maintaining the concrete test samples used <br />at a given temperature for a minimum of 24 hours <br />before applying a test load. <br /> <br /> 100 <br /> 90 <br /> 80 <br />"C 70 <br />l3 <br />...J 60 <br />'5 <br />- 50 <br />5i <br />~ 40 <br />c.. 30 <br /> 20 <br /> 10 <br /> 0 <br /> <br />" <br /> "- <br /> '" <br /> ~ <br /> "'- <br /> '--... <br /> <br />60 100 140 180 220 <br /> <br />Temperature ( F.) <br /> <br />543.2 Power-Bond Resin r~e5istanc.e To Chemicals <br /> <br />The resistance of the cured Power-Bond mortar to var- <br />ious chemicals was determined according to ASTM <br />Specification (-581 by laying molded samples of the <br />resin in the respective chemical agents. The samples <br />were subjected to a bending strength test before and <br />after a 12 month exposure to the chemicals. The <br />adhesive was rated as resistant if there was no visible <br />deterioration and less than 25 % reduction in bending <br />strength. This exposure is extreme. Under normal <br />installation conditions, the adhesive is exposed to the <br />chemical agents only at the surface of the concrete <br />around the top of the anchor hole. <br /> <br /> <br />Acetic Acid <br /> <br />Acetone <br /> <br />Ammonia <br /> <br />Aniline <br /> <br />Beer <br /> <br />Benzine <br /> <br />Benzole <br /> <br />Boric acid, <br />aqueous solution <br /> <br />Calcium carbonate, <br />suspended in water <br /> <br />Calcium chloride, <br />suspended in water <br /> <br />Calcium hydroxide, <br />suspended in water <br /> <br />Carbon tetrachloride <br /> <br />Caustic soda solution <br /> <br />40 <br />10 <br />5 <br />100 <br />100 <br />100 <br />100 <br /> <br />. <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br />. <br /> <br />. <br /> <br />. . ~~n..
