Polyesters belong to the fourth hazard class (low-hazard substances). Although when working with complex polyesters no harmful substances are released, but it is recommended to use PPE (workwear, safety glasses, cotton gloves) to avoid any skin contact. In case of skin contact, wash the affected area with warm water and soap.
Storage period is 12 months in a covered warehouse at temperature from -40 °C to +40 °C. The product can also be stored under a canopy or on a planned site, which is protected from precipitation, pollutants and mechanical damage.
