High Strength Anchoring Adhesive, MT-390/360
Structural Adhesives
Strong two-component epoxy adhesives for anchoring threaded rod and rebar in concrete and masonry
This high strength anchoring adhesive is a two-component epoxy system, designed for structural reinforcement, steel connection anchoring, and equipment base fixing. Supplied in a dual-cartridge format and dispensed through a static mixing nozzle, the adhesive ensures uniform blending for reliable performance.
With its strong bonding formulation, the adhesive delivers anchoring strength comparable to pre-installed elements, forming a secure and durable connection between threaded rods or rebar and the concrete substrate. It is ideally suited for heavy-load applications, offering long-term reliability in both new construction and retrofitting scenarios.

This high strength anchoring adhesive is compatible with most rigid substrates, excluding plastic and rubber, and is widely used across structural and infrastructure projects. Typical applications include post-installed rebar for structural reinforcement, anchoring steel structures to concrete, fixing equipment bases, securing sound barriers and guardrails on elevated roads, curtain wall support anchoring, rebar installation in building frames, tunnel pipeline anchoring, and anchoring into shear walls.
The anchoring adhesive is available in seasonal formulations, ensuring optimal performance in winter, summer, and transitional seasons, depending on the ambient temperature during installation.
