3M™ High Temperature Masking Tape 214 is a specialty heat resistant masking tape designed for high-temperature industrial applications, including use on treated metals and sensitive surfaces. Featuring a smooth crepe paper backing and a firm rubber adhesive, it provides strong holding power and excellent stain resistance.
This tape is engineered for environments where standard masking tapes fail, particularly in applications involving high heat and metal surfaces such as copper, silver, and other treated materials. Its sulfur-free adhesive makes it one of the few masking tapes suitable for use on precious metals without staining or contamination.
With temperature resistance up to 350°F (177°C) for 30 minutes, 3M 214 is ideal for bake cycles, industrial coatings, and high-temperature processing applications where performance and reliability are critical.
