3M primer 94 or 3M primer VHB UV?

3M primer 94 or 3M primer VHB UV? 

3M Primer 94 and 3M Primer VHB UV are both types of primers used in conjunction with adhesive tapes to improve the adhesion of the tape to a variety of surfaces. However, there are some differences between the two products.

3M Primer 94 is a solvent-based primer that is used to promote adhesion of vinyl films, decals, and graphics to surfaces such as painted surfaces, plastics, and metals. It is often used in the automotive and graphics industries to ensure that vinyl films adhere well and stay in place over time. It is known for its strong bonding properties and its ability to improve the durability of the adhesive tape.

3M Primer VHB UV, on the other hand, is a primer designed specifically for use with 3M VHB (Very High Bond) tapes. It is a clear, solvent-based primer that provides an excellent bond between the tape and a variety of substrates, including metals, plastics, and painted surfaces. It is formulated to resist UV light, weathering, and other environmental factors that can weaken adhesion over time.

In summary, while both 3M Primer 94 and 3M Primer VHB UV are primers that are used to promote adhesion of adhesive tapes to surfaces, they have different applications and are formulated for use with different types of tapes. 3M Primer 94 is used with vinyl films, decals, and graphics, while 3M Primer VHB UV is specifically designed for use with 3M VHB tapes and is formulated to withstand UV light and other environmental factors.
