bis(2,3-epoxypropyl) cyclohex-4-ene-1,2-dicarboxylate(CAS#21544-03-6)
Introduction
Diglycidyl tetrahydrophthalate (TDTMSE) is a common polyester compound. The following is an introduction to the nature, use, manufacturing method and safety information of TDTMSE:Quality:TDTMSE is a colorless to yellowish liquid with very low volatility and good thermal stability. It is miscible with many organic solvents but insoluble in water. TDTMSE has properties such as good flexibility, low-temperature bending and weather resistance.Use:TDTMSE is widely used in the plastics industry, the coating industry and the fiber industry. It can be used as additives such as plasticizers, solvents, lubricants, and tackifiers. When TDTMSE is combined with polymers such as polyurethane, it can improve the softness, abrasion resistance and weather resistance of the material. TDTMSE can also be used to prepare coating materials, sealing materials, and electronic materials.Method:The preparation of TDTMSE can be obtained by the reaction of tetrahydrophthalic acid (THPA) and glycidyl esters. The specific preparation method can involve the use of catalysts and appropriate reaction conditions, such as transesterification at high temperatures.Safety Information:
Application
Bis(2,3-epoxypropyl) cyclohex-4-ene-1,2-dicarboxylate (1,2,3,6-Tetrahydrophthalic acid diglycidyl ester, CAS 21544-03-6) is a low viscosity, bifunctional epoxy ester monomer used as a reactive diluent and crosslinking agent for epoxy resin systems. It features both a flexible cyclohexene backbone and highly reactive glycidyl ester groups, which polymerize with standard amine, acid anhydride, or imidazole hardeners. As a VOC-free co-monomer, it reduces formulation viscosity to enhance processability for casting, filament winding, and impregnation, thereby enabling high filler loadings and void-free composite manufacture. The saturated alicyclic structure with a double bond significantly improves the cured polymer's flexibility, impact resistance, adhesion to diverse substrates, thermal shock resistance, and hydrolytic stability. Key applications include high-performance, solvent-free coatings for aerospace, marine, and industrial protective topcoats; structural adhesives with superior toughness; carbon and glass fiber composites for lightweight automotive and wind energy components; and electrical insulating encapsulation materials for power devices, transformers, and printed circuit boards, exhibiting outstanding low-temperature performance with high shear strength and optical clarity.
