Which one is a better product for long-term elevated temperatures, HY-200 or RE 500 V3, such as rebar dowel at 110 degrees Fahrenheit?
RE 500 V3 ESR report mentions that the long-term temperature limit is 110 degrees but also provides a degradation plot in which the threshold temperature, 108 degrees, does not match the temperature axis. Please refer to the attachment.
HY-200 technical data show for condition B, long-term below 122 degrees, bonding strength should be reduced 20% for the design.
It seems the HY-200 is more appropriate for elevated temperature conditions. Is that correct? Could you provide a recommendation for the chemical adhesive used at the elevated temperature and the reduction of the bonding strength for design?
Thank you!
Hi Shawn,
HIT-HY 200 V3 and HIT-RE 500 V3 both have testing for multiple short- and long-term temperature ranges. HIT-HY 200 V3 has been tested for a maximum long-term temperature of 162 degrees Fahrenheit while HIT-RE 500 V3 has been tested for a maximum of 110 degrees Fahrenheit. It is recommended to evaluate each anchor separately to determine which adhesive may be best for your specific application. Additionally, HIT-RE 500 V3 has been tested for fire conditions for rebar development applications, as given in Hilti's Post-Installed Reinforcing in Fire Conditions.
For more technical information related to Hilti's adhesive anchors, please see the Anchor Fastening Technical Guide. For design help, engineers typically utilize Hilti’s PROFIS Engineering Suite software to perform calculations based on the specific conditions of the project. Access to the software can be found here.

Matthew
