Ditrimethylolpropane

Ditrimethylolpropane (CAS 23235-61-2), also referred to as di-TMP, is a tetrafunctional polyol derived from trimethylolpropane. Its four hydroxyl groups make it a reactive building block for producing high-crosslink-density polymers.

This chemical is essential for manufacturing esters and resins across coatings, lubricants, and adhesive systems. In synthetic lubricant manufacturing, di-TMP is esterified with fatty acids or complex acid blends.

This process produces high-performance polyol ester base fluids with strong thermal stability. Such stability is a key requirement for compressor and aviation lubricant formulations used in demanding industrial environments.

Radiation-curable and high-solids coating systems use it as a crosslinker and backbone polyol. Its functionality delivers harder films and improved chemical resistance compared to lower-functional alternatives.

Adhesive and sealant formulators incorporate di-TMP into polyurethane and polyester systems to increase crosslink density. This allows for better control over flexibility and structural integrity in the final product.

In UV-curable inks for packaging applications, it contributes to fast cure response and adhesion to demanding substrates. This makes it a preferred choice for high-speed printing and specialized industrial labeling.

Ditrimethylolpropane is supplied as a white crystalline solid or powder. Standard commercial grades include technical and industrial purity levels, typically at 98% minimum assay for consistent performance.
