Storage: Kept in airy, dry and cool room.In spite of its good storage stability, Urea Moulding Compound should not be stored under unfavorable conditions. Otherwise, a relapse of flow may be expected.
For best results, keep it under cool and dry conditions, below 25°C, and don’t put in direct contact with sunshine.
Storage period: Six months from production date. Test should be undertaken when expires. Qualified products can still be used.
