Properties and stability

Avoid contact with oxides and alkali.

Storage method

Stored in a cool, ventilated warehouse. Keep away from fire, heat sources and anti-static. Keep container tightly sealed. They should be stored separately from oxidants and alkali metals, and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency release equipment and suitable containment materials.

Synthesis method

None

Purpose

Propylene glycol methyl ether acetate is a non-pollution solvent with multi-functional groups. It is an indispensable auxiliary solvent in the coating industry to improve the strength of coating films. It is widely used in high-end paints such as car paint, TV paint, refrigerator paint, and aircraft paint.
