Chemical anchor Capsule Fischer 518821

The Fischer 518821 chemical anchor capsule is a two-component resin system supplied in pre-measured, single-use capsules for anchoring in concrete. Each pack contains ten capsules designed to deliver consistent bond strength and reliable performance for installation of threaded rods and rebar in drilled holes. The capsule format ensures correct resin-to-hardener ratio and simplifies handling on site without the need for manual mixing.

Advantages

The capsule design provides controlled, repeatable anchoring with minimal waste and reduced preparation time. Pre-measured components eliminate dosing errors and provide uniform curing properties. The chemical composition is formulated for strong adhesion to concrete substrates, corrosion resistance of the fixed element, and stable performance under static loads. Installation requires standard dispensing tools and common drilling equipment, making the product suitable for integration into existing workflows.

Suitable for

• Anchoring threaded rods and bolts in concrete
• Fixing rebar for structural connections
• Mounting base plates, railings and facade anchors
• Retrofit reinforcement and repair operations

Key specifications

• Format: pre-measured, single-use chemical capsules in a pack of 10
• Application material: hardened concrete
• System: two-component resin and hardener
• Curing: chemical cure within drilled hole at room temperature
• Working temperature range: suitable for typical construction site temperatures (follow product technical data for exact limits)
• Compatibility: for use with standard threaded rods, bolts and rebar of appropriate diameter

How to use

Drill the hole to the specified diameter and depth, then clean the hole thoroughly using brush and blow cycles to remove dust and debris. Insert the chemical capsule into the hole, then insert the threaded rod or rebar while rotating to break the capsule and mix the resin and hardener. Hold the fixing in position until initial set is achieved, then allow full cure time before applying load. Follow manufacturer guidance for hole cleaning, embedment depth, and cure times to achieve rated performance.

Usage recommendations

Use the capsule system with the recommended dispensing and setting tools, and adhere to specified drilling accuracy and hole cleaning procedures. Verify substrate condition and ambient temperature before application, and consult the manufacturer's technical documentation for specific load values, torque settings, and cure durations to ensure compliance with structural requirements.
