Top Chemical Anchors: Securely Fasten Your Installations
Discover maximum reliability with the best chemical anchors. Secure your installations with safety and peace of mind, ensuring stability and robustness in any context.
How does a chemical anchor work?
A chemical anchor is a type of fastening used to connect construction materials such as concrete, stone, or bricks. It operates through a chemical reaction that occurs between the fixing material, usually an epoxy or vinyl ester resin, and the substrate. Here's how it works exactly:
- Drilling the hole: A hole is created in the construction material where the chemical anchor will be inserted. This hole must be of specific dimensions and depth, according to the manufacturer's instructions for the anchor.
- Cleaning the hole: The hole is thoroughly cleaned to remove any debris, dust, or residue that could compromise the adhesion of the chemical anchor.
- Inserting the anchor: The chemical anchor is inserted into the hole, usually using a dispensing gun. It's important to insert the right amount of anchor to completely fill the space in the hole.
- Inserting the fastening element: The fastening element, such as a threaded rod or bolt, is then inserted into the anchor while it's still in its liquid state. It's essential to do this before the anchor starts to harden.
- Waiting time: The chemical anchor is left to harden. This may take several minutes or more, depending on the type of resin and environmental conditions such as temperature and humidity.
- Completion of the fixation: Once the anchor has fully hardened, the fastening element is securely anchored to the construction material. The chemical adhesion provided by the anchor ensures a strong and durable connection.
It's important to carefully follow the manufacturer's instructions for the chemical anchor to ensure safe and reliable fixation.
Curing Time of Chemical Anchor
The chemical anchor solidifies due to a chemical reaction that occurs during the mixing of its two components in the tube. The speed of this reaction, typical of any chemical process, depends on the temperature of the substrate, the surrounding environment, and the nature of the chemical anchor itself.
At lower temperatures, the drying process is slower. The curing time, or drying time, is also influenced by the type of resin used. For example, chemical anchors based on polyester and vinyl ester or those based on resin require less time to dry compared to epoxy-based ones. The drying time is always indicated on the product technical data sheets and on the tube label.
Bicomponent Chemical Anchor
The bicomponent chemical anchor is usually supplied with a mixing nozzle or a high-quality static mixer, ensuring extremely homogeneous mixing of the two components. If you plan to reuse the cartridge several times in a row, static mixers can be purchased separately. However, if you anticipate completing a high number of anchorages in succession, the static mixer can be reused.
When opening a new cartridge, it's important to spray a test amount until a homogeneous mixture is obtained. The application can be performed using a standard caulking gun.
