Safety & Health
- Handling Precautions
Mandatory and recommended industrial hygiene procedures should be followed whenever our products are being handled and processed.
Storage & Handling
- Storage Conditions
The components have to be stored under dry conditions below 25°C, in tightly sealed original containers. Under these conditions, the shelf life will correspond to the expiry date stated on the label. After this date, the product may be processed only following reanalysis. Partly emptied containers should be closed tightly immediately after use.Disposal - Regular procedures approved by national and/or local authorities
