TTA21 is our product name for 3,4-Epoxycyclohexylmethyl 3, 4-Epoxycyclohexane Carboxylate, one of the popular choice of cycloaliphatic epoxides. Two package and UV cure formulas use TTA21 to create better crosslink 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 contained in the system. End uses take advantage of the UV stability and low viscosity compared to other epoxy resin.

In the electrical field this end applications use the low shrink and non-conductive properties for potting compounds, insulating varnishes and an alternative to porcelain insulators.

Lastly in some halogen containing materials TTA21 performs as the preferred acid scavenger to provide package stability.

Key Feature/Benefits

• Stable to UV light makes this the preferred epoxy for exterior applications
• Low Shrinkage provides the best performance in electrical molding applications
• Low viscosity allows to formulate in higher solids
• Low conductivity gives an alternative material for electrical insulators
