Special and Unique Features
- **Snap-Together Design:** Individual cartridges can be combined to create various mix ratios (1:1 up to 25:1), offering flexibility and reducing inventory needs.- **Versatile Filling:** Can be filled through the nozzle or the back side, suitable for both manual and automated filling operations.- **Polypropylene (PP) Material:** Provides good chemical compatibility for a wide range of materials.- **Industry Standard Compatibility:** Designed to fit many industry-standard dispense guns and static mixers.- **Self-Venting Seals:** Available configurations include self-venting seals for easy filling.
Key Properties
- **Material:** Polypropylene (PP)- **Volume:** 300ml- **Outlet Thread:** 1/4-thread- **Chemical Resistance:** Good resistance to a variety of chemicals due to PP construction.- **Durability:** Lightweight yet durable for industrial use.- **Mix Ratio Flexibility:** Supports ratios from 1:1 up to 25:1 when paired with other Ratio-Pak cartridges.
Surface Compatibility
The cartridge itself is made of polypropylene. Its compatibility with surfaces depends on the two-part material it contains and dispenses. Generally, two-part adhesives and sealants dispensed from these cartridges are formulated for compatibility with a wide range of substrates, including:- Metals- Plastics (various types)- Composites- Wood- Concrete and Masonry- Glass- Ceramics
Known backups / known substitutes
- **Side-by-Side Cartridges:** Traditional dual cartridges where the two components are molded together in a single unit.- **Coaxial Cartridges:** Cartridges where one component is housed inside the other.- **Film-Pak® Cartridges:** Another type of two-component cartridge system by Nordson EFD.- **Other Brands of 2K Cartridges:** Competitors offer similar two-part empty cartridge systems (e.g., Sulzer Mixpac, COX, MK).- **Bulk Dispensing Systems:** For very high-volume applications, material might be dispensed from drums or pails using metering and mixing equipment.
Comparison Note
The Nordson Ratio-Pak system stands out due to its unique snap-together design, which allows for unparalleled flexibility in creating custom mix ratios and volumes by combining individual cartridges. This modularity can significantly reduce inventory requirements compared to fixed-ratio side-by-side or coaxial cartridges, where a specific cartridge is needed for each ratio. While other 2K cartridge systems offer similar functionality for dispensing two-part materials, the Ratio-Pak's configurable nature provides a distinct advantage for users with diverse application needs or those who frequently change mix ratios.
