How to Select Dispensing Equipment for Two-Component Acrylic AB Adhesives: A Complete Analysis of Metering Systems
Configurations
In industrial manufacturing, two-component acrylic AB adhesive (commonly known as “red-green adhesive” or structural adhesive) is widely used in automotive structural parts, battery PACK assemblies, filter sealing, electronic potting, industrial assembly and hardware & electronics industries. It features fast curing, high bonding strength, excellent impact resistance and good tolerance that does not require strict degreasing.
However, this “high-performance adhesive” can be temperamental during dispensing: it is highly corrosive, cures extremely quickly (with an open time of only 3-15 minutes), and is highly sensitive to mixing ratios.
Many enterprises often overlook metering accuracy, select inappropriate mixing methods, or use mismatched core components when choosing dispensing equipment for two-component acrylic AB adhesives. This leads to issues such as inconsistent adhesive ratios, uneven mixing, and unstable dispensing, which in turn cause bonding failure, adhesive overflow, abnormal curing, and other problems. article will conduct an in-depth breakdown of core configurations and key selection criteria.

1. Do Not Blindly Pursue “High-End”—Align with Production Needs
The core of selection is “adaptation,” not high-end equipment. For small-batch, precision dispensing, a benchtop 3-axis dispenser suffices—no need for expensive floor-standing or in-line models to avoid resource waste. Opt for in-line automatic equipment only for mass assembly line production. Select pumps and mixing systems based on adhesive ratio and viscosity to avoid overengineering or incompatibility.
