- Storage Condition
PTMG 850 is hygroscopic and will degrade if exposed to oxygen or air, so it should be well-sealed with dry nitrogen.; PTMG 850 is a white, waxy sold at room temperature, but will become a clear, colorless liquid upon heating.; If it has solidified in the drum, it can be melted by holding the drum at about 70°C for 24 hours.; Avoid localized heating however.; For storage in the liquid state, it is recommended to maintain temperature at less than 50°C.; Volatility is low, and it is unlikely to catch fire at room temperature.; But if it is burning, extinguish the fire with dry chemical, alcohol-resistant foam, or large quantities of water.; Although PTMG 850 has relatively low toxicity and is relatively safe, use standard protective equipment such as goggles and gloves when handling it.
