Scientific novelty

As part of import substitution, a film based on an organosilicon polymer has been created to replace Tesa and 3M brand laser films. The film is self-adhesive and designed for laser marking of parts with operating temperatures up to 700°C. It is water-resistant, non-flammable, and resistant to aggressive environments. The film has a high-contrast black-and-white base and is qualitatively marked and cut by all industrial lasers: gas, fiber, and ultraviolet. The fundamental novelty lies in the high-temperature resistance of the film and the unique composition of its adhesive. The film does not initially contain a pressure-sensitive adhesive like tape. Its application to parts is carried out using a special heat-resistant adhesive applied to a fragment of the film after laser marking. Once applied to a dry, degreased surface, laser labels based on the new film can only be removed by destroying them.

Advantages

Unlike analogues that operate at temperatures up to 250°C, the new film can be used at temperatures up to 700°C. Another important distinguishing feature is the low cost of the component materials. According to preliminary calculations, the cost of the film for consumers could be one-third lower than the cost of analogues on the market.

Commercial implementation

The new film can be applied in marking automotive parts, internal components for helicopter and aircraft manufacturing, and electronic automation components. It is capable of improving marking systems by completely eliminating the use of metal nameplates, dot peen and deformation technologies, and technologies involving consumables.
