Additional information

· NT CAT LA-23 is an emission-free amine catalyst. It reacts with a polyurethane matrix and therefore causes no emissions.

· NT CAT LA-23 is used in soft foam applications to meet automotive OEM emission specifications (e.g. VDA 278) and to eliminate windshield fogging or vinyl staining.

· NT CAT LA-23 is an alternative to Dabco 33-LV® catalysts and can also be used in hard foams.

· No amine catalyst emissions, no VOC emissions, no vinyl staining, and no windshield fogging are provided.

· NT CAT LA-23 is used in water foamed TDI or TDI/MDI High Rebound (HR) foams as well as TDI/MDI or MDI-based cold cured molded polyurethane foams.

· NT CAT LA-23 is an emission-free amine catalyst. This means that it does not release any harmful emissions into the air when used. This makes it a more environmentally friendly option than traditional amine catalysts.

· NT CAT LA-23 is used in a variety of polyurethane foam applications, including:

Soft foams for car seats, mattresses, and footwear

Hard foam for insulation and construction

Cold-set molding foam for medical devices and other applications

· NT CAT LA-23 offers a number of advantages over conventional amine catalysts, including:

No harmful emissions

Compatible with many polyols and isocyanates

Improved foam flow

Provides good dimensional stability


· NT CAT LA-23 is a safe and effective catalyst for polyurethane foam production. Be sure to follow the manufacturer’s instructions when using and wear personal protective equipment (PPE) when handling.
