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

Detailed description

The 2K cartridge A-System 42 ml 4:1 offers a well-designed and efficient solution for two-component product mixtures in a convenient format. Thanks to its dimensionally stable white PP cartridge body, it allows for safe and clean handling – ideal for applications demanding the highest 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 , ensuring excellent sealing and long-term functionality – even with harsh chemicals or fluctuating temperatures. The pre-installed cap securely protects the cartridge from contamination and dirt after use, increasing its shelf life and safety during storage and 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 at a 4:1 mixing ratio is crucial. The compact 42 ml size allows for easy handling, saves material, and minimizes waste.

Product properties

• Two-component cartridge (2K system), mixing ratio 4 : 1
• Contents: 42 ml (A and B components)

Suitable materials / Compatibility

The cartridge is particularly suitable for:

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

Typical application areas

• Dosage and mixing of 2-component adhesives, resins or sealants
• Repair, assembly and demonstration cases
• Laboratory tests with small quantities, e.g. material tests
• Model making or technical applications with small requirements
• Mobile applications, for example in craftsman, assembly or demonstration sets

Processing instructions

1. Shake the cartridge well before use to ensure homogeneous components.
2. Remove the cap – ensuring cleanliness.
3. Insert the cartridge into a suitable 4:1 dosing device (e.g., a 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, tightly close the cartridge and store in a cool place.
6. Dispose of residual materials properly or seal them for reuse, depending on the product specifications.
