Why Choose 3M™ Double Coated Tape 9474LE?
3M™ 9474LE combines a PET film carrier with 3M™ 300LSE Acrylic Adhesive, making it a strong choice for applications where conventional double-sided tapes may have difficulty bonding to low surface energy substrates.
Its excellent adhesion to PP and other LSE plastics, combined with good adhesion to metals and painted surfaces, makes it particularly useful for dissimilar-material bonding. The PET carrier also provides dimensional stability, while the dual-liner construction improves handling during selective die-cutting and converting.
For manufacturers requiring custom adhesive components, 9474LE is especially suitable for slitting, laminating and precision die-cutting.
Installation Guide
1. Surface Preparation
Clean the bonding surfaces and remove dust, oil, grease, moisture and other contaminants.
2. Prepare the Tape
Cut 3M™ 9474LE to the required size or use a precision die-cut component.
3. Apply the First Side
Remove the appropriate liner and apply the adhesive side to the first substrate.
4. Apply Pressure
Apply firm, even pressure across the bonding area to maximize adhesive contact.
5. Remove the Second Liner
Carefully remove the remaining liner without touching or contaminating the exposed adhesive.
6. Position the Second Substrate
Align the mating substrate accurately before making full contact.
7. Apply Firm Pressure
Press the complete assembly to establish good contact between the adhesive and substrate.
8. Allow Bond Development
The 3M 300LSE adhesive develops increasing bond strength with time and temperature. Avoid exposing the assembly to maximum loads before sufficient bond development.
Storage
Store 3M™ Double Coated Tape 9474LE in its original packaging in a clean, dry environment.
Recommended storage practices include:
- Keep the product in its original packaging
- Protect from direct sunlight
- Avoid excessive heat and humidity
- Keep away from dust and contamination
- Do not expose the adhesive to unnecessary moisture or chemicals
- Follow the latest 3M technical documentation for applicable shelf-life requirements
For production use, customers should confirm storage conditions and shelf life against the current 3M documentation for their specific product configuration.
