• OEM and precision die-cutting

Why Choose 3M 55261P Double Coated Tape?

3M 55261P combines acrylic adhesive on both sides with a thin PET carrier to support reliable bonding and convenient converting. It is a practical option for manufacturers who need a thin, transparent double-coated tape for lamination, component mounting, and precision adhesive parts.

Yousan can help evaluate suitable tape formats and converting options, including custom slitting, sheet supply, and precision die-cut components, subject to material availability and project requirements.

Installation Guide

1. Prepare the surface: Ensure bonding surfaces are clean, dry, and free of dust, oil, and release agents.

2. Check application conditions: 3M recommends an application temperature of approximately 21–38°C (70–100°F). Application below 10°C (50°F) is not recommended.

3. Apply the tape: Position the tape carefully and apply firm, even pressure to promote adhesive contact.

4. Remove the release liner: Expose the second adhesive surface without touching or contaminating it.

5. Complete bonding: Align the second substrate and press firmly across the bonding area.

6. Validate performance: Test adhesion, temperature exposure, and long-term holding power under actual operating conditions.

Storage

• Store in the original packaging.

• Recommended storage temperature: 16–27°C (60–80°F).

• Recommended relative humidity: 40–60%.

• Keep away from direct sunlight and excessive heat or moisture.

• For best performance, use within 24 months from the date of manufacture, following the manufacturer’s storage recommendations.

FAQ

1. What is 3M 55261P Double Coated Tape?

It is a double-sided acrylic adhesive tape with a thin PET film carrier, designed for bonding, lamination, and converting applications.

2. How thick is 3M 55261P?

The typical total tape thickness is 0.10 mm (3.9 mil), excluding the release liner.

3. Is 3M 55261P suitable for die-cutting?

Yes. Its thin PET carrier provides dimensional stability and supports handling during precision die-cutting and lamination.

4. Can 3M 55261P bond foam and mesh?

Yes. 3M identifies foam and mesh lamination for small electronic-device gaskets as a recommended application. Actual performance depends on the material and surface conditions.

5. What is the temperature resistance of 3M 55261P?

The technical data sheet lists typical short-term temperature resistance of 200°C and long-term resistance of 80°C. These values should not be interpreted as universal continuous-use ratings.

6. Can 3M 55261P be supplied in custom sizes?

Custom slitting, sheets, and die-cut parts may be possible through converting services, subject to available material width, processing requirements, and order quantity.
