Product description
tesa® 51920 is a white double-sided tape consisting of a PP-film backing and an acrylic adhesive.The tape is designed for customer operating under cold temperature or in unheated production environments. Normally, pressure-sensitive adhesive tapes are facing problems in cold environments due to an insufficient level of tack, which ultimately leads to a significantly lower bonding performance. Where other tape technologies fail, our tesa® 51920 shows an impressive performance at very low temperatures. These superior cold processible characteristics are a result of this product’s unique adhesive formulation.
tesa® 51920 features especially:
- Excellent bonding opportunities down to -10°C
- Secure bond even on high surface energy substrates (e.g. steel) and medium surface energy substrates (e.g. ABS)
- Outdoor suitability
- Unique blue liner in combination with this film tape to indicate its cold performance properties
Main applications
- Bonding of plastic trims and profiles
- Mounting of edge profiles on plastered surfaces
- Mounting of profiles and signs in industrial, walk-in or commercial refrigerators
Additional Info
Liner variants:PV1 = white PE-coated paper liner (122µm thickness)
PV15 = blue HDPE film liner (100µm thickness)
Certificates & documents:
- Certificate of conformity for bonding of labels of shelves in icehouses (corresponding with LFGB, directives 2011/10/EC, 1935/2004/EC, 19/2004/EC and German Consumer Goods Act
- LEED assessment (VOC content acc. to ASTM D 2369-10
- Byggvarubedömningen's conformity (Sweden)
Temperatures below 0°C can lead to frosted/iced surfaces. Bonding to such surfaces will not enable our product to be used in a safe and permanent way. Therefore, it's of high importance to reduce any surface contamination including ice and frost before bonding.
