Trimethylolpropane (TMP)
Trifunctional Polyol for Resins, Coatings and Polyurethane Systems
CAS 77-99-6
Trimethylolpropane is a trifunctional polyol used as a building block for alkyd resins, polyester systems, polyurethane chemistry, adhesives, and industrial intermediates.
Why Trimethylolpropane
- Trifunctional alcohol for building crosslinked polyester and polyurethane systems
- Low acid value and low moisture profile support resin and coating formulations
- White flake form is suitable for solid-material handling and charging
