For quality reasons WA papers should be stored originally packed. Storage & converting conditions of 20±5°C and 50±10% rel. humidity are recommended. WA papers should not be exposed to strong mechanical friction, e. g. by scratching with finger nails. The durability of WA papers in original packaging is min. 12 month.
We always recommend comprehensive testing of materials prior to regular conversion.
