Injection Adhesive Undercut Anchor
Chemical Anchors
Undercut anchor bolt with injection anchoring adhesive
This anchoring system integrates a metal undercut anchor with MT500 injection adhesive, delivering a combination of mechanical interlock and chemical bonding. Designed to withstand high temperatures and certified for 100-year service life, it merges the strengths of chemical and mechanical anchors for dual-load transfer, providing exceptional load-bearing capacity, seismic resistance, and impact durability.
The modified epoxy adhesive offers strong adhesion, flexibility, and complies with non-toxic and hygienic standards. The system requires only a small drill hole diameter, minimizing structural damage during installation. All components have undergone rigorous performance testing to ensure long-term anchorage stability and reliability in critical applications.
