The 701-M part from 3M is a polyurethane foam tape with a very low initial adhesion, which increases over time. It is often used for gasketing, draft stopping, and seaming door bottoms and frames, where quick and easy application are desired. The 701-M foam is often used in combination with other 3M products such as VHB (Very High Bond) tape and Fills and Wraps. 3M’s 701-M tape is a permanent, flexible mounting solution that bonds to a variety of substrates, including wood, metal, glass, and plastic. It is highly resistant to shocks, temperatures, and chemicals, so it can be used in a variety of applications, including automotive, medical, and aerospace.
