When selecting a two-component adhesive, evaluate whether the application is potting, bonding or casting, together with substrates, geometry, processing and operating environment.
When Polyurethane Is Often Considered
Polyurethane systems can combine electrical insulation, flexibility and environmental protection. Their ability to accommodate vibration and differences in thermal expansion can suit sensitive or multi-material assemblies.
- Assemblies exposed to vibration or thermal movement
- Applications where excessive rigidity may stress components
- Water-treatment, filtration and selected precision assemblies
- Projects requiring tailored hardness, viscosity or cure behavior
When Epoxy Is Often Considered
Epoxy systems are often considered when rigid encapsulation, high mechanical strength and dimensional stability are central requirements. On compatible substrates, they can provide strong structural support and durable bonding.
- Power electronics and rigid electrical assemblies
- Applications requiring structural support
- Industrial sensors and mechanically demanding components
- Bonding or potting where dimensional stability matters
Compare the Complete Application
An effective comparison includes substrate adhesion, section thickness, mixing and dispensing, working time, cure conditions, thermal cycling, moisture exposure and mechanical stress. Do not optimize one property at the expense of the complete assembly.
