Mastic is packed and transported in metal barrels in accordance with the requirements of GOST 6247-79* or flasks in accordance with GOST 5799-78*. It should be stored in a packaging container in rooms or other places protected from the influence of solar radiation, at temperatures from 5 °C to 30 °C separately by brand; must follow the rules for storing flammable materials. The warranty period of mastic storage is 6 months from the date of manufacture.

Mastic is not only a fire - explosive, but also a toxic material, so it must be handled carefully.
