3M 7000123293 | 72 yd x 2.000" Width x 3.4 mil Thickness Specialty Application Tape

Description

3M 7000123293 is a 72-yard roll of 838 weather-resistant film tape, measuring 2.00" × 3.4 mil and designed for long-term outdoor protection and sealing. The tape has a thin Tedlar (PVF) film backing that provides exceptional tensile strength and dimensional stability without adding bulk, while the solvent-resistant acrylic adhesive provides immediate tack and long-lasting adhesion to metals, painted surfaces, glass, and many plastics. Because there are no plasticizers, the 3M 838 tape is resistant to aging and staining while remaining flexible over a wide temperature range. This specialty application tape is recommended for curtain wall seams, window and door seals, hinge seals, and protective wrapping in areas where weathering, solvents, and UV exposure are a concern. Installers benefit from a thin profile that conforms to contours while providing a long-lasting barrier against moisture, fuels, and common industrial fluids, making it a practical choice for building, aerospace, signage, and exterior trim applications.

Product Features and Benefits

Tedlar PVF film backing for strength without thickness

The 3M 838 tape uses PVF film, which has high tensile strength and puncture resistance while remaining thin (3.4 mil overall thickness), preserving profile and fitting within tight tolerances.

Solvent- & temperature-resistant acrylic adhesive

After exposure to hydraulic fluids, jet fuel, and a wide temperature range, the adhesive maintains high shear and peel performance, allowing for reliable, long-term bonding.

Excellent weathering and UV resistance

The 3M 838 weather-resistant film tape is designed for long-term outdoor exposure; it resists yellowing, chalking, and chemical attack to maintain sealing integrity over time.

Low-plasticizer formulation for long-term aging

With no added plasticizers, migration and staining are reduced, ensuring stable adhesion and minimal discoloration in critical visual applications.

Thin and conformable for tight assemblies

The tape's 3.4 mil thickness allows it to conform to small radii and irregular substrates, making it ideal for window, door, and trim sealing without adding bulk.

Frequently Asked Questions

Is 3M 838 tape heat resistant for cold weather use?

Yes, the 838 formulation remains flexible and functional over a wide service temperature range, making it suitable for both cold and hot environments.

Is 838 an exterior weather-resistant double-sided tape?

The 3M 838 is a weather-resistant film tape with a single face and a Tedlar backing that is ideal for exterior sealing and protection.

Is 3M cold weather tape heat resistant?

3M 838 exhibits thermal stability and maintains adhesion after temperature cycling, so it is suitable where cold-weather performance is required.
