Packaging and storage
Packaging
This product is available in 20 kg pail and 200 kg drum kits.
Storage
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.
