Useful ranges and selection cautions.

These are family level planning ranges. The selected commercial grade and its current data sheet control the design.

SubstratesGrade specific PC, PBT, PA, metal or other
Bond mechanismHeat activated selective adhesion
PrimerOften eliminated when substrate matches
Peel strengthDepends on substrate, mold temperature and aging
CycleBond development can affect demold time
ContaminationMold release and handling oils can prevent bond
StorageComponent handling limits matter
Key cautionSupplier substrate list never replaces molded adhesion test
