Is 3M 467MP adhesive safe for iPhone Duo metal frame coating?

I’m considering using 3M 467MP double-sided adhesive tape to secure a dbrand case directly to the metal frame of my Night Sky iPhone Duo, as the original adhesive strips have worn out and dbrand does not sell replacements separately.

Could anyone please confirm whether the acrylic adhesive in 3M 467MP is chemically safe with the iPhone Duo’s metal frame coating? Specifically, could prolonged contact with the adhesive or its removal cause discoloration, staining, peeling, or other damage to the finish?

If compatibility cannot be confirmed, could anyone recommend a specific type of removable adhesive that is safe for the coating and can be removed without leaving residue or causing damage?

Thank you!

None of the users here can answer that, however, on something as new as the Duo I would only consider using Apple’s case until Apple certifies other manufacturers.

For something as new as the Duo, I agree with Lawrence Finch and would likely only buy a case from Apple until other cases are tested. Though I did just see this article about some other cases (in addition to the Apple Case) and the referenced brands are quite reputable --> https://www.zdnet.com/tech/best-iphone-duo-case/

Apple has used the same PVD coating on titanium frames in previous iPhone generations. I was hoping someone could weigh in on how well Apple’s PVD coating holds up to acrylic adhesive, or share what type of adhesive strips Apple uses in its own Duo cases.
