Di(trimethylolpropane) is widely used in the production of alkyd resins, which are essential components in paints, coatings, and varnishes. Its polyfunctional nature allows it to act as a crosslinking agent, enhancing the durability, hardness, and chemical resistance of the final product.

In the adhesives industry, it serves as a key raw material for synthesizing polyurethane adhesives, providing excellent bonding strength and flexibility. It is also utilized in the manufacturing of radiation-curable coatings, which are applied in electronics, automotive, and packaging industries for their fast curing and high-performance properties.

Additionally, it finds application in the production of lubricants and plasticizers, where it improves thermal stability and reduces viscosity. Its role in the synthesis of specialty polymers and elastomers further highlights its versatility in various industrial applications.
