Chemical Anchoring Adhesive, MT-500
Structural Adhesives
Injectable adhesives for anchoring rebar and threaded rod in concrete and masonry
Chemical anchoring adhesive is a high-performance two-component adhesive with epoxy and hardener, developed for modern structural reinforcement, retrofitting, and anchoring applications. Packaged in a durable dual-cartridge system and applied through a static mixing nozzle, the adhesive ensures thorough and consistent on-site mixing.
Certifications & Standards
- Complies with GB 50367-2013 (Code for Design of Reinforcement for Concrete Structures)
- Certified under ETA for use in both cracked and non-cracked concrete
Designed for demanding structural environments, it offers a long working time combined with fast load-bearing performance. It delivers exceptional resistance to seismic loads, impact, and fatigue, tested up to 2 million cycles. The structural anchoring adhesive is engineered to withstand hot and humid aging for over 100 years, maintains strong performance in acidic and alkaline conditions, and exhibits zero creep, non-toxicity, and no odor, making it suitable for both interior and enclosed applications.
The chemical anchoring adhesive is widely used for post-installed rebar, threaded rods, and anchor bolts in buildings, tunnels, bridges, metro systems, and industrial structures where long-term stability and certified reliability are essential.
