3M™ Pressure Sensitive Acrylic Foam Tape 4257YCL is a 0.38 mm (0.015 in) thick, gray, double-coated acrylic foam tape used in a variety of automotive applications where bonding surfaces are well matched or where the parts to be bonded are thin and flexible.
3M AFT 4257YCL has AR-5 adhesive on the liner side of the product for bonding to automotive paint surfaces, and DS-6 adhesive on the non-liner side of the product for bonding to the exterior trim part. 3M AFT 4257YCL is equivalent to 3M™ Pressure Sensitive Acrylic Foam Tape 4215 used by Japanese OEMs but offers an adhesive system designed for bonding to North American paint systems.
Since product performance will depend on actual conditions within a specific application, it is essential that the user evaluate the 3M product to determine whether it is fit for a particular material purpose and suitable for the user’s method of application.
