tesa® 68812
50μm double sided mounting tape for low surface energy (LSE) substrates
Product Features
- Excellent bonding strength, even on LSE and rough substrates
- Excellent tack and fast activation
- Very good shock resistance
Product description
tesa® 68812 is a black, double sided self-adhesive tape, consisting of a black PET backing. The modified acrylic adhesive ensures a very high tack and high bonding strength on polar and non-polar substrates.
It is equipped with double PET liner. The double-sided tape is specifically designed to have excellent adhesive strength on low surface energy (LSE) and rough substrates. Additionally, it offers very good push-out, shock, and ageing resistance.
