Oct 14, 2026 Leave a message

Trimethylolpropane (TMP) is an important organic chemical raw material widely used in coatings, resins, polyurethanes, adhesives, and fine chemicals.

Because the trimethylolpropane molecule contains multiple hydroxyl groups, it exhibits some hygroscopicity and may absorb moisture from the air in humid environments. Therefore, during storage and transportation, it should be kept in sealed packaging and protected from prolonged exposure to high-humidity conditions.

 

Proper storage methods can effectively preserve the product quality and performance of trimethylolpropane, ensuring its stable use in industrial production.
