Monument Chemical Tripropylene Glycol (TPG)

Monument Chemical Tripropylene Glycol (TPG) is a clear, slightly viscous, practically odorless liquid. Hygroscopic, it is completely soluble in water and miscible with many organic solvents. TPG (Tripropylene Glycol) is used for textile soaps, lubricants, and cutting oils. It is also used as a chemical intermediate in urethanes and as a solvent in coatings and inks.

    Safety & Health

    Health & Safety Information
    • Under current U.S. OSHA's Hazardous Communication  program TPG is not considered hazardous.
    • Observe good industrial hygiene practices and use appropriate Personal Protective Equipment.

    Storage & Handling

    Storage & Handling
    • General industry practice is to store TPG in carbon or  stainless steel vessels. 
    • TPG should be stored only in tightly closed, properly  vented containers away from heat, sparks, open flame  or strong oxidizing agents. 
    • Handle empty containers carefully. Combustible  residue remains after emptying.
    • Provided proper storage and handling precautions are taken, TPG manufactured and delivered by Monument Chemical is stable for at least 12 months from the date of manufacture. TPG that is subsequently repackaged, handled and/or delivered by third parties may have a different shelf life and may require third party shelf life studies. Product past the retest date should be evaluated to confirm that all specifications  are within their limits before use.
