Specify by zone first, substrate second
The zone sets temperature, UV and vibration requirements before the material does.
Exterior trim: black exterior-grade foam VHB 5915/5925/5930/5952/5962; grey 5604/5608/5611 where the joint also seals.
Qualify the actual clearcoat — many low-VOC paints are low-energy; use LSE-rated foam where standard acrylic fails.
Long trim needs thicker foam and a mechanical locator so peel cannot start at the ends.
Interior plastics: 300LSE (9495LE/93005LE/93010LE/93015LE); tissue 88641–88644 where a PET carrier would telegraph through.
Squeaks and rattles: select by gap and relative motion, not adhesion — tesa PET fleece 51026/51618/51608/51036, PE and PU foam.
Under-hood: tesa 51407 polyimide, Nitto Nittoflon PTFE, aluminium foil, Scotch electrical tape.
Validate with peel and shear after dwell, thermal cycling, humidity, cold application and an aged re-test.
