In the dynamic world of bonding and assembly, precision, convenience, and consistent performance are non-negotiable. The Two-Component 400ml 1:1 Adhesive Cartridge (also known as a dual cartridge or double cartridge) emerges as a game-changer, designed to meet the diverse needs of professionals across industries while simplifying the application of two-part adhesives. This innovative packaging solution—available as both pre-filled adhesive cartridges and empty cartridges for custom filling—combines optimal capacity, accurate ratio control, and user-friendly design, making it an indispensable tool for industrial production, professional DIY projects, and even specialized fields like dental applications with dedicated dental cartridges. Crafted from durable materials like PP (polypropylene) and PA (polyamide), this dual barrel cartridge ensures compatibility with a wide range of adhesives and sealants, solidifying its role as a versatile packaging choice.

1. Product Overview: Design That Delivers Precision

At the core of this adhesive cartridge is its commitment to ratio accuracy—a critical factor for two-component adhesives, where incorrect mixing ratios can lead to weakened bonds, incomplete curing, or even project failure. The 1:1 mixing ratio is pre-engineered into the dual cartridge’s dual-chamber structure, ensuring that Component A and Component B (hence the term AB cartridge) are dispensed in equal volumes every time. This eliminates the guesswork of manual measuring, reduces material waste, and guarantees consistent bonding performance batch after batch—whether you’re using a pre-filled Epoxy Cartridge, Silicone Sealant Cartridge, or a custom-filled empty silicone cartridge.

With a total capacity of 400ml (200ml per chamber), this dual tube cartridge strikes the perfect balance between portability and usability. It’s compact enough to handle in tight spaces (such as automotive interior repairs or electronic component assembly) yet large enough to minimize the need for frequent cartridge replacements during high-volume tasks. The cartridge’s construction—often using chemical-resistant PP or PA—protects adhesives and sealants from external contaminants (moisture, dust, UV light) and prevents leakage, preserving the product’s shelf life and effectiveness. For users seeking flexibility, empty cartridges in the same 400ml 1:1 configuration are available, allowing for on-demand filling with specific adhesives or sealants tailored to unique project needs.

The dual cartridge is equipped with a static mixing nozzle (compatible with standard 1:1 dispensing guns) that ensures thorough blending of the two components as they are dispensed. This integrated mixing system eliminates the need for separate mixing bowls or tools, reducing cleanup time and preventing cross-contamination between batches—whether you’re working with an Epoxy Cartridge for structural bonding or a Silicone Sealant Cartridge for weatherproofing. Additionally, disposable cartridges (including disposable dual glue cartridges) in this design offer added convenience for single-use or small-batch projects, eliminating the need for post-use cleaning and ensuring fresh adhesive/sealant for every application.
