With a thickness of 0.040 inches (1.0 mm) and a width of 3 inches, this tape is ideal for exterior applications including cargo trailer rail seals, HVAC enclosures, roof sealing, truck and trailer roof sealing, and other industrial applications where a reliable water-tight seal is demanded. The linerless design supports sustainability goals by eliminating traditional liner waste without compromising performance.
This product comes as a 3-roll case, with each roll measuring 36 yards in length. The tape operates effectively from 10°C to 93°C (50°F to 200°F) and features UV resistance, humidity resistance, heat resistance, and low temperature resistance. The 24-month shelf life ensures long-term storage capability, making it a dependable choice for maintenance, repair, and operations (MRO) professionals across construction, general industrial, metalworking, signage, solar, and specialty vehicle industries.
