tesa® 6925 Temperature-Resistant Label Stock

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.
