BARRIERTA L 25 DL is based on perfluorinated polyether oil and PTFE and thus resistant to many media such as water or hydrocarbons. Do you need to attain low friction coefficients in elastomer/metal or plastic/plastic friction points over a long time and across a wide temperature range? BARRIERTA L 25 DL can help you keep friction low even at temperatures of -25 °C, especially when lubricating seals in train doors. This will enable you to meet requirements for low pressure variations in trains going through tunnels and constant actuating forces for doors over a wide temperature range. For train door seals, which might come into contact with passengers' clothes, BARRIERTA L 25 DL SPRAY is particularly beneficial because it can be applied in a very thin lubricant film. This helps prevent the contamination of passengers with lubricant while enabling any trapped pieces of clothes to be pulled free with a minimum of force. Do your customers expect a long service life of seals, even if they are frequently exposed to direct sunlight? BARRIERTA L 25 DL absorbs some of the sunlight's UV radiation, keeping the seal pliant for longer. Do you need a lubricant that is compatible with sensitive materials? Field experience has shown the product's good compatibility with many sensitive plastic materials such as PC, or with elastomers such as EPDM. Do you have optical applications requiring a lubricant that does not form a condensate on lenses? With the low vapour pressure of its base oil, BARRIERTA L 25 DL offers what it takes to prevent the formation of condensates. Application BARRIERTA L 25 DL is preferably used for lubricating seals in train doors. It has also been used as a special lubricant for optical equipment for many years. When using BARRIERTA L 25 DL SPRAY, you can apply a lubricant film of very low thickness. The application of BARRIERTA L 25 DL SPRAY to the seal is also particularly fast, enabling optimised processing times for each door seal. Application notes Seals in train doors should be free from impurities prior to initial lubrication. When applying BARRIERTA L 25 DL SPRAY, the spray bottle should be shaken forcefully several times prior to spraying as well as at least once per minute during application. For use in precision optics, we recommend cleaning the friction point prior to initial application first with white spirit 180/210 and then with Klüberalfa XZ 3-1. Then blow the surfaces with clean, dry compressed air or hot air to remove solvent residues. For the initial lubrication the friction point must always be blank (that means free of oils, greases and perspiration) and free of soil particles.
