Spezifische Merkmale von ELASTOSIL® LR 3025/40 A/B

  • Niedriger Druckverformungsrest ohne zu tempern
  • schnellvernetzend

ELASTOSIL® LR 3025/40 A/B is particularly suitable for the economical production of large series of injection molded articles. Parts made from ELASTOSIL® LR 3025/40 A/B can generally be used for technical applications without postcuring, but do not comply with regulations concerning use in the pharmaceutical and food industry. Due to their optimized stability against fuel cell gases and high resistance to effects related to noble metal migration, ELASTOSIL® LR 3025/40 A/B is mainly used to manufacture gaskets for fuel cells.

The A and B components are delivered ready to use in 20 kg pail and 200 kg drum kits. With adequate metering equipment, they can be pumped directly from the original containers into the injection molding machine and mixed by a static mixer. The mixing ratio is 1 : 1. At room temperature, mixtures of A and B components have a pot life of at least three days.

Lagerung

Once opened, containers should always be resealed after use to prevent the platinum catalyst from being poisoned by amines, sulphur or phosphorus compounds. The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
