| The components have to be stored in tightly sealed and dry original containers in an environment at 6~35℃;. Under these conditions, the shelf life will correspond to the expiration date stated on the label ( normally 12 months). After this date, the product may be reanalyzed to confirm if it validates yet. Partial emptied containers should be closed tightly immediately after use. | Storage |
| LW-9527A 20 or 220 or 1200kg/drum, LW-9527B 20 or 220 or 1200kg/drum; | Packing |
| If eyes are contaminated by epoxy resin, hardener or mixture for casting, the eyes should be treated and washed immediately by clean running water for 10 to 15 minutes. If necessary, the person shall be sent to hospital. If the skin is stained or splashed by the materials, it shall be wiped immediately and washed off by clean water. If the person feels very hurt or burn wounds, he or she shall be sent to hospital immediately. If the clothes are Contaminated, the people shall change the suits immediately. If the operator breathes in the vapour and feel bad, he or she shall be moved to outside. Any other doubt, please consult doctors or us for medical assistance. | First aid |
