Know what is on the surface
Oil, dust, corrosion, coatings and mould-release residue can affect adhesion. Identify the surface that the adhesive will actually contact.
Choose a compatible cleaning process
Follow the relevant substrate and adhesive guidance. Cleaning must remove contamination without damaging the part or leaving an incompatible residue.
Use treatments deliberately
Abrasion, primers and other treatments are process choices that need validation. More treatment is not automatically better, and a primer is not a universal substitute for cleaning.
Control the interval before bonding
Handling, storage and exposure after preparation can reintroduce contamination. Record preparation timing and protect the prepared surfaces.
Make the process repeatable
Document the materials, method and acceptance checks. Validate on production-representative parts and maintain the preparation steps in the work instruction.
TAKE IT INTO YOUR PROCESS
A repeatable preparation process is part of the adhesive system.
Build an application briefGeneral application guidance. Follow the current grade-specific technical and safety data sheets, and validate the finished assembly.
