tesa® 6925 Black
Printable, self-adhesive and tamper-evident
Product description
tesa® 6925 marking foil is especially recommended when high durability and superb resistance against the highest temperature are required.
The acrylic film is self-adhesive and printable with high contrast which leads to a high initial readability rate; even on high density barcodes. The dimensionally stable material is resistant against chemicals, abrasion, temperature, ageing and UV-light. The adhesive system consists of a resin modified acrylic suitable even for low energy surfaces.
This high performance product is used as a tamper-evident identification sealing label over the entire lifetime of a product and also as a data carrier system for intelligent in-process steering. A typical application is the marking of circuit boards. tesa® 6925 even resists brazing and cleaning processes.
Available in: white

Additional Info
Printability:
Sheet screen printing is recommended. Paint adherence and chemical resistance need to be evaluated on a case to case basis.
Thermal Transfer:
tesa® 6925 is suitable for precise and high contrast thermal transfer printing.
The quality of the marking depends on the combination of printer and ribbon. In order to achieve the best results, the printing speed and the temperature of the curing bar should be varied.
