Frequently Asked Questions
Yes. The pressure-sensitive adhesive activates immediately upon application and works with standard 3-inch core tape dispensers. The 3/4" width fits most industrial tape heads. For optimal adhesion on dispenser rollers, ensure the dispenser is clean and adjust tension settings for your specific line speed.
The silicone adhesive thermosetting properties strengthen the bond as temperature increases, preventing edge curl or separation during freeze-thaw cycles. The woven glass cloth construction maintains conformability even at 392°F, ensuring secure adhesion to irregular core shapes without cracking or lifting.
Yes. This tape is rated for voltages up to 3,000V, making it suitable for standard industrial electrical applications up to 480V. The flame-resistant woven glass cloth meets safety requirements for motor leads, control circuits, and splice applications in manufacturing environments.
At 3/4" width, one 66-foot roll covers approximately 33 linear feet of double-wrapped insulation or 66 feet for single-layer wrapping. For case sealing applications, tape consumption depends on dispenser configuration and overlap width. We recommend keeping 3-4 rolls in stock for continuous production lines to avoid downtime.
