Preparing your resin cartridge properly before use is essential for achieving a consistent and reliable adhesive bond. One often overlooked step is bleeding the cartridge before application.
Why Bleeding the Cartridge Matters
Bleeding a resin cartridge simply means dispensing a small amount of product through the nozzle before you begin your actual task. This process helps ensure that both components of the resin are flowing evenly and are thoroughly blended. Skipping this step can lead to poor mixing, which may affect the strength and finish of your adhesive bond.
How to Bleed a Resin Cartridge
- Attach the appropriate mixer nozzle — for example, the “Mixer Nozzle” for 50ml Araldite 2000 series.
- Slowly squeeze out a small amount (about 1–2cm) of resin material.
- Ensure that the dispensed resin appears consistently mixed with no streaks or colour separation before starting your main application.
This simple step ensures you’re applying properly mixed resin right from the start.
When This Step is Especially Important
Bleeding the cartridge is particularly vital when precise bonding and maximum adhesive performance are required—for example, when working on structural repairs, detailed crafts, or high-strength bonds. It’s also important whenever you begin with a new cartridge or change to a fresh mixer nozzle.
