Application of Trimethylol propane TMP

Trimethylol propane TMP is mainly consumed as a precursor to alkyd resins. Otherwise, acrylated and alkoxylated TMP's are used as multifunctional monomers to produce various coatings, Ethoxylated and propoxylated TMP, derived condensation of from TMP and the epoxides, are used for production of flexible polyurethanes. Allyl ether derivatives of TMP, with the formula CH3CH2C(CH2OCH2CH=CH2)3-x(CH2OH)x are precursors to high-gloss coatings and ion exchange resins. The oxetane TMPO is a photoinduceable polymerisation initiator.

1) Used for producing Alkyd resins,Saturated polyesters.
2) Used for producing Synthetic lubricants,plasticizer,printing ink.
3) Curing agent for coating.
4) Textile auxiliary agent, heat stabilizer for PVC.
5) Used for producing emulgator.
