- Storage Information
ELASTOSIL® LR 3003/50 US A/B has a shelf life of at least 12 months when stored below 32°C in the tightly closed original container. Storage beyond the recommended shelf-life does not necessarily mean that the product is no longer usable. However, the properties required for the intended use must be checked for quality assurance reasons. Once opened, containers should always be resealed to prevent catalyst poisoning by amines, sulfur compounds, and other substances.
