Cobra Primer is an alternative product to the 3M Primer 94.
Liquid adhesive primer for demanding applications. Aids and strengthens adhesive on vehicle wraps and VHB double-tapes
• Use to improve vinyl adhesion where the vinyl will be stretched or heated into concave areas
• Great for use on complex vehicle contours
• Works with all brands of vinyl
• Also great for paint-primed surfaces, low-energy plastics, and practically any surface that is difficult to get vinyl adhesive to adhere to
• Tape Primer can be used to promote the adhesion of tapes to surfaces such as PE, PP, ABS, PC, PBT/PET, Glass, metal and painted surfaces. It is easy to be applied.
Warning: Tape Primer can increase the possibility of damage to paint when vinyl is removed because it increases adhesion. It is very important to consider this possibility before application.
Application: Shake the Tape Primer well before using. Apply a thin, sparing amount of the primer to both parts of your materials using a foam printer swab. Allow the primer to dry thoroughly before applying tape(5 mins at room temperature). Be sure the primed surfaces remain clean before applying the tape.
