Storage & Handling

Handling Precautions

In order to allow complete melting, pre-heat materials at following conditions (melting times are referred to 200 kg drums,stored at 20°C)
After pre-heating, make sure all materials are completely melted.
Well mix melted material by drilling or rolling the drum.
Load materials to the machine immediately after mixing.
Materials must be stored under nitrogen blanket after use.
Pre-heating temperature (°C) - 60
Pre-heating time (hours) - 16
