Ditrimethylolpropane
What is Ditrimethylolpropane?
Ditrimethylolpropane (CAS 23235-61-2), also referred to as di-TMP, is a tetrafunctional polyol derived from trimethylolpropane.
Where is Ditrimethylolpropane used?
- Coatings: crosslinker and backbone polyol in radiation-curable and high-solids systems
- Lubricants: esterified with fatty acids or complex acid blends to produce polyol ester base fluids with strong thermal stability
- Adhesives and sealants: incorporated into polyurethane and polyester systems to increase crosslink density
- UV-curable inks: contributes to fast cure response and adhesion to demanding substrates
- Its four hydroxyl groups make it a reactive building block for high-crosslink-density polymers.
Commercial specifications
- 98% minimum assay
- Technical and industrial purity grades
- Bags or drums for bulk industrial procurement
