What is 3,4-Epoxycyclohexylmethyl 3,4-epoxycyclohexanecarboxylate?
Description
3,4-Epoxycyclohexylmethyl 3,4-epoxycyclohexanecarboxylate TTA21S is a pale yellow to colorless transparent liquid. Two package and UV cure formulas use TTA21 to create better crosslinks and enhance adhesion. Each molecule creates high cross-linking due to the dual epoxide functionality, which can react with hydroxyl, carboxyl, or amine groups of polymers in the system. End users take advantage of the UV stability and low viscosity compared to other epoxy resins.
Chemical properties
Pale yellow to colorless transparent liquid
The Uses of 3,4-Epoxycyclohexylmethyl 3,4-epoxycyclohexanecarboxylate
This compound can be made by treatment of the corresponding bis-unsaturated ester with peracetic acid. It is used as a reactive diluent, for filament winding, as an acid scavenger, or as a plasticizer. Vapor hazard is slight at ambient temperature because of its moderately high boiling point. Skin contact is to be avoided.
The Uses of 3,4-Epoxycyclohexylmethyl 3,4-epoxycyclohexanecarboxylate
EEC is an epoxy monomer that can be used as a resin in aerospace, electronics and automobile industries as an adhesive and a composite material.
General Description
3,4-Epoxycyclohexylmethyl 3,4-epoxycyclohexanecarboxylate (EEC) is a cycloaliphatic epoxy that can be synthesized by the reaction of 3′-cyclohexenylmethyl 3-cyclohexenecarboxylate with peracetic acid.
