Blue Polyester High-Temperature Masking & Flash Tape

IPG 6120 is a specialized, blue polyester (PET) film tape engineered with a pressure-sensitive, high-performance silicone adhesive. Designed for demanding industrial and aerospace applications, it serves as a direct performance equivalent to 3M Polyester Tape 8991. The combination of its ultra-thin, flexible PET backing and silicone adhesive provides superior chemical and solvent resistance, exceptional conformability around complex contours, and razor-sharp paint lines without bleed-through.

Aviation Depot Advantage: Rated for continuous operation at temperatures up to **356°F (180°C)**, IPG 6120 is an essential shop consumable for powder coating masking and composite autoclave flash tape applications. Its specialized silicone adhesive ensures clean, one-piece removal without ghosting, tearing, or leaving sticky adhesive residue behind on metal alloys, composite structures, or avionics printed circuit boards (PCBs).

Ordering Information:
• Please verify your required roll dimensions and case quantities with our aviation supply specialists before completing your purchase.

Key Characteristics & Benefits

• Direct 3M 8991 Alternative: Interchangable with 3M Polyester Tape 8991, offering top-tier technical performance at a cost-effective price point.
• 356°F Thermal Resistance: Engineered for continuous exposure up to 356°F (180°C) during powder coating bake cycles and composite heat cures.
• High-Performance Silicone Adhesive: Delivers exceptional holding power and peels away cleanly without leaving adhesive transfer or ghosting.
• Chemical & Moisture Resistance: Inherently resistant to aggressive solvents, chemicals, and moisture penetration during wet shop processing.
• Thin & Conformable PET Backing: Strong 1-mil polyester backing offers high tensile strength and tear resistance while maintaining a low-profile edge for crisp paint lines.

Typical Aviation Applications

• Powder Coating Masking: Primary tape choice for masking precision aerospace components, brackets, and cowlings prior to entering high-temperature powder curing ovens.
• Autoclave Composite Flash Tape: Deployed in composite fabrication and metal bonding to hold material layers, vacuum bags, and breather cloths during autoclave curing cycles.
• Avionics & PCB Protection: Used in electronics manufacturing to protect printed circuit boards and sensitive components during conformal coating or soldering processes.
• General High-Heat Touch-Up: Ideal for localized airframe repairs involving heat lamps, infrared curing, or high-temperature paint bake cycles.

We understand that certain projects, maintenance schedules, or regulatory standards require strict specifications. If your order has specific shelf-life requirements, please proceed as follows:

How to Request: If you require a specific Date of Manufacture (DOM), Date of Expiration (DOE), or a specific minimum shelf-life percentage (%), you must clearly state this requirement:

In the Comments/Notes section when placing an online order.

Explicitly written on your Purchase Order (PO) or quote request email for offline orders.

Validation Process: Once your requirement is received:

We will ship your order if the available stock matches your specifications.

If we do not have the exact batch, we will contact you prior to shipping with the shelf-life percentage (%) or dates we have available for your acceptance.
