Important Instructions
- Since Saint-Gobain cannot predict or regulate every probable application, it is strongly recommended to test this product under individual application settings before commercial use.
- Surfaces have to be clean and free of dust, oil, moisture, grease, and dirt. Isopropyl alcohol is ideal for cleaning the surface.
- Apply an even pressure of 103 kPa (15 psi) to boost optimal contact between the tape and the material to be bonded. The application temperature must be between 16 °C and 52 °C (between 60 °F and 125 °F). Applying these tapes at temperatures below 16 °C (60 °F) is not recommended as the adhesive does not flow in this setting and can cause poor bonding.
- The adhesion between the substrate and the tape improves with time, usually reaching final bond strength in 72 hours. The adhesion process can be accelerated by heating the product over 40 °C (105 °F).
Shelf Life
The shelf life for this product is 24 months after the date of manufacture, provided it is stored in original packaging at 50% relative humidity and temperatures of up to 21 °C (70 °F).
