DABCO 33-LX/Dabco 33-LX catalyst

DABCO 33-LX/Dabco 33-LX catalyst


Product Name: DABCO 33-LX, Dabco 33-LX Catalysts

Alias: Dabco 33-LX, Dabco 33-LX catalyst, tertiary amine catalyst 33-LX, tertiary amine catalyst 33-LX


Product Description: Dabco 33-LX Catalyst for Low Atomization Automotive Molded Foam Systems, Innovative Diol Solution of 33% Triethylenediamine, Low Emissions.


Dabco 33-LX is a blend of 33% triethylenediamine (DABCO solid amine) and a non-dispersive proprietary solvent carrier that is a versatile catalyst for the polyurethane industry. Dabco 33-LX has a significant impact on promoting urethane (polyol-isocyanate) reactions in a variety of flexible and rigid foam applications.

Dabco 33-LX can be used in the automotive interior foam industry where VOC’s and fogging are required to reduce emissions and thus windshield fogging due to the non-dispersive solvent carrier.

Dabco 33-LX is a tertiary amine catalyst that strongly promotes urethane (polyol-isocyanate) reactions in a variety of flexible and rigid foams.


Versatile polyurethane amine catalyst

Polyurethane gel catalyst to promote late stage reactions in polyurethane foams

Liquid, easy to meter and use

Non-emitting solvent, reduces fogging


Dabco 33-LX Catalyst can be used as a 3:1 replacement for Dabco Solid Amine (Triethylene Diamine) Catalyst in all foam formulations. For example, 0.3 pphp Dabco 33-LX Catalyst replaces 0.1 pphp Dabco Solid Amine (Triethylenediamine) Catalyst;

The dosage of Dabco 33-LX Catalyst is identical to that of Dabco 33-LV Catalyst.

Storage and Packaging.

Airborne Chemical Products recommends that all polyurethane catalysts be stored in a dry, cool and properly ventilated area, and that all storage containers be well sealed to avoid contact with water or other influential substances which may alter the performance of the product in use. The storage temperature is 10°C to 30°C. Lower or higher temperatures are inappropriate and should be avoided if possible.
