Installation Guide
1. Prepare the Bonding Surface
Clean and dry the bonding surfaces. Remove dust, oil, grease, release agents, and other contaminants.
2. Check Substrate Compatibility
Test the tape on the actual materials before production. Particular attention should be given to low-surface-energy plastics, textured surfaces, and plasticized materials.
3. Cut or Convert the Tape
Cut the tape to the required size or use a customized die-cut shape when appropriate.
4. Apply the Tape
Apply the tape evenly to the first substrate. Use firm and uniform pressure to improve adhesive contact.
5. Remove the Liner
Remove the liner carefully without touching or contaminating the exposed adhesive surface.
6. Bond the Second Substrate
Align the second material accurately and apply sufficient pressure across the complete bonding area.
7. Allow Adhesion to Develop
Allow sufficient time for the adhesive bond to develop before applying significant loads. The required time depends on the materials, temperature, pressure, and application conditions.
Important Application Notes
- Do not apply the tape to contaminated or wet surfaces.
- Conduct compatibility testing before mass production.
- Do not interpret short-term temperature resistance as continuous operating temperature.
- For critical applications, conduct peel, shear, ageing, and environmental testing.
- For roll applications, suitable dispensing equipment may improve application consistency.
Storage
For optimal product performance:
- Store the tape in its original packaging.
- Keep it in a clean and dry environment.
- Protect the tape from direct sunlight.
- Avoid excessive heat and humidity.
- Prevent contamination and dust exposure.
- Avoid pressure or deformation of the roll edges.
- Follow the latest manufacturer storage and shelf-life recommendations.
Storage conditions can affect adhesive performance, liner release, and product usability.
