Compare systems in context
Epoxies, polyurethanes and methacrylates cover different combinations of process and performance. A family name alone does not establish suitability for a particular assembly.
Design the load path
Distribute loads over the bond area and account for peel, cleavage and differences in stiffness. Joint design can matter as much as the selected adhesive.
Match working time to assembly time
Allow time for dispensing, placement and any adjustment. Fixture time describes handling development; it is not the same as full cure or readiness for service.
Control mixing and dispensing
Use the correct component ratio and compatible dispensing equipment. Ratio by volume and ratio by weight are different instructions and must not be interchanged without documented guidance.
Use representative testing
Validate the exact substrates, coatings and preparation. Include relevant environmental conditioning and inspect the failure mode, rather than relying only on a single strength value.
TAKE IT INTO YOUR PROCESS
The adhesive, joint geometry and dispensing process should be developed together.
Build an application briefGeneral application guidance. Follow the current grade-specific technical and safety data sheets, and validate the finished assembly.
