Trimethylolpropane (TMP)
CAS 77-99-6
Trimethylolpropane (TMP) is a trifunctional alcohol used as a building block for alkyd resins, saturated polyesters, polyurethane systems, adhesive resins, and related intermediates. The current product-page data is based on publicly available manufacturer and reference sources and is suitable for commercial drafting, while final grade, assay, and release criteria should still be confirmed against supplier TDS and COA.
- Trifunctional structure supports crosslink density in alkyd, polyester, and polyurethane resin systems
- Used as a building block for adhesive resins, saturated polyesters, and polyurethane intermediates
- Solid flake form supports handling and downstream charging in industrial resin production
- Useful where UV resistance and chemical resistance are important performance targets
