Why Choose 3M™ 9628B?

3M™ 9628B combines Quick Bonding Adhesive 360 with an ultra-thin black PET carrier to deliver strong adhesion in a compact construction.

Its ability to bond many low surface energy plastics, including PP and PE, makes it particularly useful for applications where conventional double-sided tapes may have difficulty achieving reliable adhesion.

The 0.05 mm construction is thinner than 3M™ 9629B, making 9628B suitable for assemblies with limited bonding space. Its PET carrier also improves handling and dimensional stability during precision converting.

For manufacturers requiring thin, black, high-tack double-sided tape for plastic bonding, electronic components, and industrial assembly, 3M™ 9628B is a versatile solution.

Installation Guide

1. Surface Preparation: Clean both bonding surfaces to remove dust, oil, grease, and other contaminants.

2. Surface Drying: Ensure the substrates are completely dry before applying the tape.

3. Tape Application: Apply 3M™ 9628B evenly to the first substrate.

4. Liner Removal: Carefully remove the natural glassine release liner without touching the exposed adhesive.

5. Component Positioning: Align the second component accurately before making contact.

6. Pressure Application: Apply firm, uniform pressure to ensure intimate contact between the adhesive and substrate.

7. Bond Development: Allow sufficient time for the adhesive bond to develop before subjecting the assembly to demanding loads.

For PP, PE, and powder-coated surfaces, conduct adhesion testing under actual production conditions.

Storage

• Store in the original packaging.

• Recommended storage temperature: approximately 21°C (70°F).

• Keep in a clean, dry environment.

• Protect from direct sunlight and excessive humidity.

• Avoid contamination from dust, oil, and other substances.

• Prevent excessive pressure or deformation during storage.

• Follow the manufacturer’s recommended shelf-life guidelines. Distributor listings commonly state a 24-month shelf life; verify the applicable batch documentation.

FAQ

1. What type of adhesive does 3M™ 9628B use?

It uses 3M™ Quick Bonding Acrylic Adhesive 360 on both sides of a black PET film carrier.

2. What is the total thickness of 3M™ 9628B?

Its total tape thickness is approximately 0.05 mm (2 mil), excluding the release liner.

3. Can 3M™ 9628B bond polypropylene (PP)?

Yes. It is designed to provide strong adhesion to low surface energy materials, including polypropylene.

4. Is 3M™ 9628B suitable for polyethylene (PE)?

Yes. It is suitable for many polyethylene surfaces, including HDPE and LDPE. Actual adhesion should be confirmed on the specific material.

5. What is the difference between 3M™ 9628B and 9629B?

Both use Quick Bonding Adhesive 360 and a black PET carrier. Their main difference is thickness:

• 9628B: approximately 0.05 mm (2 mil).

• 9629B: approximately 0.10 mm (4 mil).

9628B is designed for thinner bonding applications, while 9629B provides a thicker adhesive construction.

6. What is the difference between 3M™ 9628B and 9628FL?

Both belong to the 9628 series and use Quick Bonding Adhesive 360. 9628B has a black PET carrier, while 9628FL uses a clear PET carrier.

7. Is 3M™ 9628B suitable for die-cutting?

Yes. Its PET carrier improves dimensional stability and handling during slitting and precision die-cutting.

8. What is the operating temperature range of 3M™ 9628B?

Published product information lists a minimum operating temperature of approximately -40°C and a maximum of 93°C. Actual performance depends on the substrate, bonding conditions, and exposure duration.

9. Is 3M™ 9628B a foam tape?

No. It is an ultra-thin double-coated PET film tape with a total thickness of approximately 0.05 mm, not a foam tape.
