For several decades 3M has developed a wide variety of masking tapes to fit the needs of the industrial consumer. However, with such a wide variety, choosing the right product has become a very intimidating task. In order to help companies efficiently choose the most appropriate masking tapes for their applications, 3M™ introduced a 5 tier industrial masking system with 5 levels of increasing performance.
3M 101+ is a basic, economical masking tape suitable for light indoor usage like: marking, temporary holding, wrapping and sealing. However, it is recommended to reserve critical paint masking applications for higher level 3M masking tapes. (Withstands temperatures up to 150°F (66°C) for 30 minutes)
3M 201+ provides all the general use capability of 3M 101+ while providing better paint line performance, higher heat resistance and greater conformability. (Withstands temperatures up to 200°F (93°C) for 30 minutes)
3M 301+ is a distinctly yellow colored masking tape for better visibility and identification. This tape makes further improvements in strength, temperature resistance and paint performance. (Withstands temperatures up to 225°F (107°C) for 30 minutes)
3M 401+ is another incremental improvement in strength, temperature resistance and paint performance. This tape features a distinct green backing for visibility and identification. (Withstands temperatures up to 250°F (121°C) for 30 minutes)
3M 501+ is the ultimate choice for 3M’s industrial masking lineup. It features the best strength, conformability and masking performance with a significant improvement in temperature resistance to allow for higher temperature applications. (Withstands temperatures up to 300°F (149°C) for 30 minutes)
