Storage & Handling

Storage & Handling

Powder should be stored at 10°C or below, in closed containers. After removal from cold storage, the material must be allowed to come to room temperature in the sealed container to avoid moisture contamination. Suggested waiting time is 24 hours. Please consult our Product Handling Recommendations for Coating Powders. For safe handling information on this product, consult the Material Safety Data Sheet (SDS).
