tesa® 6957 is a high heat resistant two-layer, brittle acrylic laser markable film with a unique, forgery-proof watermark design that is embedded into the material as prove of originality.
Marking and cutting are achieved by laser in one step, which makes it possible to realize any desirable label variation and format using only one material. The product is highly durable and resistant against thermal, chemical, mechanical and environmental (weathering) influences for secure traceability over entire vehicle lifetime.
The adhesive system consists of a special acrylic adhesive system, which leaves an UV-detectable trace (“UV-Footprint”) on most surfaces as required by GB/T 25978 (P.R.C.) and NHTSA §541.5 (USA).
