Alias: DABCO 33-LSI

Foreign name

Meaning Unknown solution of 33% triethylenediamine (improved odor compared to A33)

Form Solid

Application Flexible, semi-rigid, rigid urethane foam


Dabco 33LSI catalyst is a 33% diol solution of triethylenediamine (odor improvement over A33), which has the same excellent properties as crystalline triethylenediamine, and due to its low viscosity liquid, it also has ** handling characteristics, being completely soluble in water, and readily miscible with other urethane raw material components such as polyols, fluorocarbons, and others.


Suitable for a wide range of polyurethane applications

Gel catalyst

Excellent handling characteristics

Improved foam odor


Dabco® 33LSI catalyst can be used in all polyurethane foam applications, where it can be used as a one-to-one replacement for Dabco® 33LV or at one-third the amount of triethylenediamine crystals used, e.g., 0.3 parts of Dabco® 33LSI for 0.1 parts of triethylenediamine crystals.
