[Shop-talk] removing 3m Super Windshield and Gasket Adhesive

[alfuller194 at gmail.com]

Following is the composition of the super weatherstrip and gasket adhesive from the 3M site at: https://www.3m.com/3M/en_US/p/d/v000087446/

 

If this is the same product you have you can see the ingredient list is mainly naphtha, Hexane and MEK.  Interesting that the stuff when cured does look and feel like a polyurethane. My chemistry is rusty enuogh to prohibit me from commenting on whether this qualifies.

 

I’m not sure what would be a solvent for this combination and they don’t say in that data sheet.   As others have said 3M does have good support folks, and they sell an adhesive remover
