Considerations for 2K Gap Fillers
Compared to 1K gap fillers, 2k gap fillers come with considerations in the form of manufacturing complexities, including:
- Precise mix control required for optimum material performance
- Mixing elements increases dispense pressure
- Long mixing nozzle may complicate application in space constricted areas and edges
- Increased initial capital investment and maintenance cost
Considerations for 1K Gap Fillers
Depending on the given designs and processes, certain gap fillers may be better suited than others. The manufacturing ease of a 1K gap filler comes with considerations, including:
- Dependence on environmental conditions for its cure performance
- Dependence on the bondline geometry
- Limited knobs in its toolbox to tune its cure speed
- Limited chemistry selection diversity and market availability
