3M Scotch-Weld EPX II Applicator, PN 021200-50004, 1 Applicator and 3 Plungers for Two-Part Structural Adhesive Dispensing
Manual mixing of two-part structural adhesives introduces the risk of incorrect mix ratios, uneven component delivery, and inconsistent bond quality that is not acceptable in structural repair and composite bonding applications where the integrity of the cured adhesive is the basis of the repair. Supplied by JHEARs Aerospace, the 3M Scotch-Weld EPX II Applicator is the professional dispensing tool for 200ml and 400ml EPX cartridges, dispensing both components simultaneously and at the correct ratio on every trigger pull to deliver a reliably mixed adhesive at the application point without guesswork, manual mixing errors, or wasted material from poorly proportioned batches.
In aviation repair, composite bonding, and structural adhesive applications, the mix ratio is not a guideline but a requirement for full cure strength. The EPX II applicator removes the human variable from the mixing process, ensuring consistent adhesive quality across every job the tool is used on. The kit includes one applicator and three plungers, providing the hardware for multiple jobs straight from the box without the need to source additional plunger stock before getting started.
Spec: 3M Scotch-Weld EPX II Applicator, PN 021200-50004. Compatible with 200ml and 400ml EPX two-part adhesive cartridges. Simultaneous dual-component dispensing at correct mix ratio. Kit includes 1 applicator and 3 plungers. Suitable for structural adhesive, composite bonding, and precision two-part adhesive applications.
Who this is for: Aircraft repair technicians and composite bonding engineers requiring consistent, correctly proportioned two-part adhesive dispensing, MRO professionals using 3M Scotch-Weld EPX structural adhesive cartridges in repair and assembly applications, and engineering workshops where the quality and reliability of structural adhesive bonds depends on precise mix ratio delivery at the application point.
FAQ
Which 3M Scotch-Weld EPX cartridge sizes is this applicator compatible with?
The EPX II Applicator is designed for use with 200ml and 400ml 3M Scotch-Weld EPX two-part adhesive cartridges. It is not compatible with 50ml dual syringe formats or single-component products. Verify the cartridge format of your specific 3M adhesive product before purchasing the applicator.
What is the purpose of the three included plungers and when would additional plungers be needed?
The plungers drive the adhesive components out of the cartridge during dispensing. They are not typically replaced during normal use of a single cartridge, but having three plungers in the kit provides spares for extended use across multiple cartridges and job sessions. Replace a plunger if it shows signs of deformation or if adhesive has cured on it between uses.
Does using the EPX II applicator guarantee a correct mix ratio without additional manual mixing?
The EPX II applicator dispenses both adhesive components simultaneously at the designed cartridge ratio, but full mixing requires using the appropriate 3M EPX static mixing nozzle attached to the cartridge, which combines the two components as they are dispensed. The applicator and mixing nozzle together deliver correctly mixed adhesive at the tip, eliminating the need for manual mixing on a palette.
Why should I purchase my adhesive dispensing tools from JHEARs Aerospace?
