The 24mm x 175mm Epoxy Acrylate Capsule is a glass chemical anchor cartridge designed to bond threaded bars, studs or rebar into drilled holes in concrete and masonry. Activation is by the spin-in method: inserting and rotating the threaded bar breaks the glass vial and mixes the epoxy‑acrylate resin and hardener to form a cured adhesive bond between the anchor and substrate. The capsule is intended for heavy-duty anchoring where a bonded connection is required rather than a mechanical expansion.

Each capsule contains a two‑component epoxy‑acrylate system housed in a sealed glass tube. The product is supplied at 24mm external diameter and 175mm length, suitable for use in drilled holes sized for nominal 24mm capsules. The adhesive chemistry is formulated for ambient-temperature curing; cure speed and final properties depend on substrate temperature and the diameter of the anchoring element. The system is compatible with standard metric coarse-thread bars (M‑series) and deformed reinforcing bars, and is commonly used with zinc-plated, hot-dip galvanised or stainless threaded rods depending on the corrosion protection required.

Use of chemical anchors should follow recognised design guidance. The capsule is intended to be used within installation procedures and calculations compliant with BS EN 1992‑4 (Design of fastenings for use in concrete) and with industry acceptance methods such as ETAG/ETA or the corresponding European Technical Assessments where applicable. The product is manufactured under ISO 9001 quality controls and tested to internal and third‑party protocols appropriate for chemical anchoring systems.

Typical applications include structural connection of balustrades and handrails, fixing base plates for machinery, installing safety barriers and façade anchors, and specialist marine and civil engineering fixings when paired with suitable corrosion‑resistant anchor bars. Key benefits are the creation of a continuous bonded layer that reduces point stresses, excellent load transfer for static and dynamic loads, and improved corrosion protection of the embedded bar compared with dry contact in many situations. For aggressive or offshore environments, pairing the capsule with stainless anchors is recommended to ensure long‑term durability.
