Dabco EG is a strong-gelling tertiary amine catalyst that is a solution of 33% triethylene diamine (TEDA) and 67% ethylene glycol;

Dabco EG can be used to catalyze the urethane (polyol-isocyanate) reaction in flexible foams, commonly used in shoe soles, and in polyurethane self-skinning products.


DABCO EG catalyst is a polyurethane tertiary amine that is a solution of 33% triethylenediamine (TEDA) and 67% methylene glycol (MEG). DABCO EG catalyst is a powerful catalyst for urethane reactions (polyol-isocyanate), typically used in shoe soles, but also in flexible foam applications.


Versatile polyurethane amine catalyst

Polyurethane gel catalyst for late-stage reactions in polyurethane foaming

Liquid, easy to dose and use


DABCO EG catalyst in the form of liquid DABCO solid amine catalyst is suitable for any polyurethane formulation extended with ethylene glycol (MEG), such as microcellular elastomers for shoe soles.

DABCO EG catalyst is also recommended for integral skin foam applications.

Shelf Life.

Keep unopened for two years

Storage and Transportation:

Should be kept sealed and stored in a dry, cool, ventilated warehouse


200KG/drum Storage: it is recommended to store in dry and cool area with proper ventilation. Please fasten the packaging cover as soon as possible after the original packaging to prevent the mixing of other substances such as moisture and other substances that may affect the product performance.
