tesa® 64912 PV0
Double-sided PE foam tape
Product Features
- High initial adhesion to LSE and MSE surfaces without primer
- Near to ultimate peel adhesion level right after application
- Good performance at an application temperature as low as 5°C
Product description
Primer process is annoying but essential for many suppliers in the Automotive Industries nowadays!
The introduction of tesa® 64912 can help our customers eliminate the primer in the process1!
tesa® 64912 is a double-sided PE-foam tape. Its high performance adhesive enables primerless bonding of Low Surface Energy (LSE) and Medium Surface Energy (MSE) substrates.
Features:
- High initial performance to LSE and MSE surfaces without primer
- Reach ultimate peel adhesion level right after application
- Superior peel adhesion on PP substrates, even at an application temperature down to 5 °C
- Reliable performance at higher temperature
- Highly conformable and gap filling
- Excellent converting properties
Benefits:
- Eliminate the primer in the production process
- Enable a much more efficient and robust application
- Skip the pre-heating of tape in winter time
- Realise a healthier working condition
- Reach a more environmental friendly production
(*) For glass and soft EPDM substrates primer is still needed.
