Why Choose 3M™ Adhesive Transfer Tape 9773WL?
The key advantage of 3M™ 9773WL+ is its combination of high-tack 300MP+ acrylic adhesive and carrierless construction.
Unlike a conventional double-coated tape with a PET, tissue or foam carrier, an adhesive transfer tape consists primarily of adhesive on a release liner. This allows the adhesive to conform closely to irregular and textured surfaces.
The 300MP+ adhesive is particularly useful for manufacturers working with foam, fabrics, plastics, wood and gasket materials, while its ability to flow into surface irregularities without heat can improve contact on challenging substrates.
For converters, the 96 lb polycoated kraft liner also provides a practical construction for slitting, laminating and precision die-cutting.
Installation Guide
1. Prepare the Surface
Clean the bonding surfaces and remove dust, oil, grease, moisture and other contaminants.
2. Cut the Tape
Cut 9773WL+ to the required dimensions or use a precision die-cut adhesive component.
3. Apply to the First Substrate
Remove the release liner and carefully apply the exposed adhesive to the first substrate.
4. Apply Pressure
Apply firm and uniform pressure across the bonding area. Adequate pressure helps maximize adhesive contact.
5. Remove the Liner
Remove the remaining release liner carefully to expose the second adhesive surface.
6. Position the Second Substrate
Align the mating material accurately before applying it to the adhesive.
7. Apply Pressure
Press the complete assembly firmly and evenly.
8. Allow Bond Development
The adhesive develops increasing bond strength with time. 3M indicates that full adhesion develops within approximately 48–72 hours under appropriate conditions.
Storage

FAQ
What is 3M™ Adhesive Transfer Tape 9773WL?
3M™ 9773WL+ is a carrierless adhesive transfer tape using 3M™ Adhesive 300MP+ acrylic adhesive. It is designed for bonding foams, plastics, wood, fabrics and other substrates.
Is 9773WL a double-sided tape?
It provides adhesive bonding on both sides of the liner, but technically it is an adhesive transfer tape, not a carrier-based double-coated tape.
What adhesive does 9773WL use?
The current 9773WL+ uses 3M™ Adhesive 300MP+, a high-tack acrylic pressure-sensitive adhesive.
Does 9773WL have a carrier?
No. It is a carrierless adhesive transfer tape. The adhesive is coated directly onto the release liner.
How thick is 3M™ 9773WL+?
The adhesive thickness is 3 mil (0.076 mm), excluding the liner.
Can 9773WL bond foam?
Yes. Foam bonding and gasket fabrication are important applications for this product.
Can 9773WL bond fabric and textiles?
Yes. 3M specifically identifies fabric and textile bonding, including floor covering lamination, as applications.
Can 9773WL bond polypropylene?
Yes. 3M’s published performance data includes adhesion to polypropylene (PP).
Is 9773WL suitable for rough surfaces?
Yes. Its carrierless adhesive construction and adhesive flow characteristics make it suitable for textured and rough surfaces.
Can 9773WL be die-cut?
Yes. The 96 lb polycoated kraft liner is suitable for converting and die-cutting processes.
What is the difference between 9773WL and 9773WL+?
The current 3M product is 9773WL+, using 3M™ Adhesive 300MP+. Older technical documents refer to 9773WL with 300MP adhesive. For new product listings, the current 9773WL+ designation should be used while retaining “9773WL” as a searchable legacy/common model term.
