Precautions for handling
1. Temperature | |
Sheets may change shape when heated to 70°C or over for HALS-PP,
or 50°C or over for HALS-PETG. Accordingly, please avoid storing the product in locations where atmospheric temperatures rise above 40°C. |
|
2. Solvents | |
Paints and solvents can cause HALS to change shape by eroding its
surface, so please avoid storing in locations such as storage rooms for painting materials, spraying rooms or were solvent fumes may infiltrate. |
|
3. Storage | |
Please store HALS horizontally, stacking items only of similar dimensions above it. | |
4. Disposal | |
When disposing of this product, please do so in accordance with the law, and conditions stipulated by regional governing bodies. | |
5. Period of storage | |
The maximum storage period for HALS in environmental conditions tested
at 23°C after shipping is: 3 months for the PP material, and 6
months for the PET material. |
