2K cartridge A-System 42 ml 4:1 – self-venting, white PP, EPDM O-ring

detailed description

The 2K Cartridge A-System 42 ml 4 : 1 offers a sophisticated and efficient solution for two-component product mixtures in a handy format. Thanks to its dimensionally stable PP cartridge body in white, it allows safe, clean handling—ideal for applications that require maximum precision and repeatability. The integrated self-venting lip piston ensures that air bubbles escape automatically, guaranteeing a homogeneous mixture without interference.

Both pistons (A and B pistons) are equipped with high-quality EPDM O-rings, which ensure excellent tightness and long-term functionality—even with difficult chemicals or changing temperature conditions. The pre-mounted cap protects the cartridge from contamination and dirt after use, increasing its shelf life and safety in storage or during transport.

Whether in the laboratory, workshop, or production environment, this cartridge is ideal for applications such as adhesives, sealants, resins, or other two-component systems where precise dosing in a 4:1 mixing ratio is crucial. The compact 42 ml size allows for easy handling, saves material, and minimizes waste.

product features

Suitable materials / Compatibility

The cartridge is particularly suitable for:

• Polyurethane, epoxy, or silicone resins
• Reactive adhesives (2K-based) with a 4:1 ratio
• Sealing and casting compounds – also for small volumes
• Applications in laboratory and production environments, engineering and prototyping workflows

Typical areas of application

• Dosing and mixing of 2K adhesives, resins, or sealants
• Repair, assembly, and demonstration cases
• Laboratory tests with small quantities, e.g., material tests
• Model making or technical applications with low demand
• Mobile applications, such as in craftsman, assembly, or demonstration kits

Processing instructions

1. Shake the cartridge well before use to prepare homogeneous components.
2. Remove the cap – ensuring that it is clean.
3. Insert the cartridge into a suitable 4:1 dosing device (e.g., 50 ml gun or smaller versions).
4. Extrude evenly and slowly to avoid air bubbles – the self-venting function helps with this.
5. After use, close the cartridge tightly and store in a cool place.
6. Dispose of residues properly or seal them for reuse, depending on the product specifications.
