Product Name
Individual Air-Free Pistons for the MixPac 50ml 1:1 ratio cartridges
Brief Description
These are individual, air-free, auto-release pistons specifically designed for MixPac A-System and B-System 50ml 1:1 ratio cartridges, as well as Atlas Professional 50ml 1:1 ratio cartridges. Their primary function is to ensure precise, air-free dispensing of two-part adhesives, epoxies, silicones, urethanes, and other chemical compounds, preventing air entrapment that can compromise material integrity and dispensing accuracy.
Popular Applications & Uses
- Precision bonding in various manufacturing processes.- Sealing and potting applications.- Encapsulating electronic components.- Structural adhesive applications in furniture and millwork.- Panel bonding, concrete repair, and waterproofing.- Repackaging bulk materials or creating field repair kits.- Dispensing custom formulations with precision.- Assembly work and higher volume dispensing applications.
Industries that Commonly Use It
- Aerospace/Defense- Artist, Artisan- Automotive Service/Repair- Cabinet & Woodworking- Chemical Industry (for handling 2-part fluids)- Construction/ Building Services- Concrete (for concrete repair)- Energy (solar power, wind turbines)- Engineering Services- Furniture- General Manufacturing- Industrial Supply- LED/Electronics (potting, automated assembly)- Medical Device/ Prosthetics (general 2K adhesive applications, though not for dental/medical cartridges)- Mold Making/ Casting (for potting compounds)- Packaging Services or Contractor (for repackaging)- Prosumer (for professional and DIY use)- Transportation/ Specialty Vehicle
Special and Unique Features
- **Air-Free Auto-Release Technology:** Designed to prevent air entrapment during filling and dispensing, ensuring material integrity and precise application.- **Self-Venting Design:** Eliminates the need for shims or bleed plugs during the packaging process, simplifying and speeding up cartridge preparation.- **Improved Shape and Robust Sealing Lips:** Facilitates easy centering and insertion into the cartridge.- **Stability Ring:** Helps keep the piston properly aligned within the cartridge, effectively preventing material leakage.- **PBT Valve Plate:** Provides high chemical resistance, ensuring compatibility with a wide range of two-part materials.- **HDPE Piston Body:** Offers flexibility for a tight seal with the cartridge body and enhances resistance to external factors like pressure, temperature, and vibration during transport and storage.- **One-Step Insertion Process:** Contributes to faster and more efficient filling operations.- **Enhanced Shelf Life:** Protects the adhesive material from external influences such as oxygen permeation and vapor transmission, extending product longevity.- **Specific Compatibility:** Engineered to fit MixPac A-System and B-System 50ml 1:1 ratio cartridges, and Atlas Professional 50ml 1:1 ratio cartridges.
Key Properties
- **Precise Metering and Mixing:** Crucial for achieving optimal performance of two-part adhesives and sealants.- **Air-Tight, Leakproof Seal:** Ensures secure containment of materials, contributing to safe shipment and extended shelf life.- **Broad Chemical Compatibility:** Suitable for use with various two-part materials including epoxies, silicones, urethanes, acrylics, and polyurethanes.- **Durability:** Often constructed from robust materials like polypropylene (PP) to withstand demanding industrial environments.- **Consistent Dispensing:** Prevents common issues like tunneling and suck-back, leading to accurate and repeatable material deposits and reduced waste.- **Optimal A/B Proportioning:** Designed to maintain the correct mix ratio for two-part systems, which is essential for the adhesive's performance.
Surface Compatibility
The pistons themselves are compatible with the internal surfaces of MixPac 50ml 1:1 ratio cartridges, typically made of polypropylene (PP) or other chemical-resistant plastics. The PBT valve plate ensures high chemical resistance against the dispensed two-part materials, which commonly include epoxies, silicones, acrylics, and polyurethanes.
Known backups / known substitutes
- **Other Piston Types:** Alternatives include Multi-Seal with Integral Center Bleed Plug Pistons and Solid Multi-Seal Pistons, though these may require shims for air bleeding.- **Traditional Pneumatic Dispensing Systems:** These systems often rely on air pressure directly on the material, which can lead to air entrapment, inconsistent dispensing, and material degradation.- **Different Cartridge Ratios/Sizes:** While this product is for 50ml 1:1 cartridges, MixPac offers cartridges and pistons for various ratios (e.g., 2:1, 4:1, 10:1) and larger volumes (e.g., 200ml, 400ml, 600ml, 1500ml).
Comparison Note
Individual Air-Free Pistons for MixPac 50ml 1:1 ratio cartridges offer significant advantages over conventional piston designs and traditional air-driven dispensing methods. They provide superior precision and reliability by actively preventing air entrapment, which is a common issue with other systems that can lead to voids, inconsistent mixing, and compromised material performance. The self-venting and auto-release features simplify the filling and sealing process, reducing labor and potential errors. Furthermore, their robust construction and enhanced sealing capabilities contribute to a longer shelf life for the stored adhesives by protecting them from external environmental factors. This results in reduced material waste, lower operating costs, and more consistent, high-quality applications.
