MixPac DMA50 Dispenser for 50ml Epoxy & Adhesives - Configurable for all Ratios (1:1, 2:1, 3:2, 4:1, and 10:1 ratios)

Product Name

MixPac DMA50 Dispenser for 50ml Epoxy & Adhesives - Configurable for all Ratios (1:1, 2:1, 3:2, 4:1, and 10:1 ratios)

Brief Description

The MixPac DMA50 Dispenser is a manual, hand-held dispensing gun engineered for the precise and consistent application of two-part (2K) epoxies and adhesives from standard 50ml "square-back" cartridges. It is designed to accommodate a wide range of mixing ratios through interchangeable plungers, making it a versatile tool for various bonding, sealing, and repair tasks in industrial, professional, and DIY settings.

Popular Applications & Uses

• General bonding, sealing, and repair operations across various assembly tasks.
• Sealing joints and bonding structural components.
• Cabinetry, veneer application, and wood joinery in woodworking and furniture manufacturing.
• Applying adhesives with accuracy in circuit boards, sensors, and micro-components for electronics assembly.
• Bonding small parts in automotive and aerospace applications where precise glue properties are critical.
• Controlled deposits of epoxy resins, two-part silicones, PU polyurethanes, potting compounds, and doming resins.

Industries that Commonly Use It

• Aerospace/Defense
• Artist, Artisan (for crafts and DIY projects)
• Automotive Service/Repair
• Cabinet & Woodworking
• Construction/ Building Services
• Fabrication (general bonding and assembly)
• Furniture
• General Manufacturing
• LED/Electronics
• Medical Device/ Prosthetics (for device assembly, not direct medical application)
• Metal Fabrication (for bonding metals)
• Mold Making/ Casting
• Packaging Services or Contractor
• Prosumer (combining professional and consumer use)
• Transportation/ Specialty Vehicle

Special and Unique Features

• Universal Cartridge Compatibility: Works with all standard 50ml “square-back” cartridges from popular brands such as ChemSet™, Lord, Loctite, Araldite, Devcon, and 3M.
• Multi-Ratio Configurability: Easily configurable for various mixing ratios including 1:1, 2:1, 3:2, 4:1, and 10:1, typically through easy-swap or integrated plungers.
• Ergonomic and Durable Design: Features a lightweight, impact-resistant hardened plastic (PBT & Reinforced Nylon) and steel construction with an ergonomic design to minimize hand fatigue during extended use.
• Accurate and Consistent Dispensing: Ensures precise and consistent metering of components, which is crucial for achieving optimal adhesive performance and bond strength.
• No-Drip System: An integrated pre-release mechanism prevents messy drips, ensuring clean application and reducing material waste.
• Versatile Use: Suitable for a broad spectrum of users, from industrial professionals to DIY enthusiasts.

Key Properties

• Cartridge Capacity: Primarily designed for 50ml cartridges, with some DMA series also accommodating 75ml.
• Supported Ratios: 1:1, 2:1, 3:2, 4:1, and 10:1 (configurable with appropriate plungers).
• Compatible Materials: Two-part epoxies, acrylics, urethanes, MMAs, silicones, PU polyurethanes, potting compounds, and various other 2-component adhesives and sealants.
• Construction Materials: PBT & Reinforced Nylon, and Steel.
• Dispensing Output: Each full hand squeeze typically produces approximately 4.1 grams of epoxy (equivalent to two plunger clicks).
• Operation Type: Manual, hand-held.

Surface Compatibility

The MixPac DMA50 Dispenser is compatible with a wide range of surfaces that are typically bonded by two-part epoxies and adhesives. This includes, but is not limited to, metals, various plastics, ceramics, composite materials, and wood.

Known backups / known substitutes

• Other MixPac Models: For specific cartridge types, such as dental or medical cartridges, or S-Type 'rounded-back' 50ml cartridges, alternative MixPac models like the DS53 or DS51 are recommended.
• Competitor Manual Dispensers: Other manual 50ml cartridge guns from manufacturers such as Chem-Set (e.g., PAK-50), Nordson EFD, and Infinity Bond (e.g., DMA Cartridge Gun) serve as direct substitutes.
• Pneumatic Dispensers: For applications requiring higher volume, reduced operator fatigue, or integration into semi-automated processes, pneumatic dispensers (e.g., MixPac DP2X series, Infinity Bond Versa Air Pneumatic Cartridge Gun) offer a powered alternative.
• Automated Dispensing Systems: For high-volume production lines and robotic applications, fully automated dispensing systems provide the highest level of precision and repeatability.

Comparison Note

The MixPac DMA50 Dispenser stands out as an "industry standard" for manual 50ml two-part adhesive dispensing. Its key advantages lie in its broad compatibility with numerous adhesive brands and its exceptional versatility in handling multiple mixing ratios with simple plunger changes. While automated systems offer higher throughput for large-scale manufacturing, the DMA50 provides a cost-effective, reliable, and user-friendly solution for precision application, offering superior control and consistency compared to basic, non-ratio-specific manual applicators.
