Polycat SA-1


Name: Delayed Catalyst SA-1

Alias: delayed catalyst SA-1, Polycat SA-1, catalyst SA-1, polyurethane catalyst SA-1, polyurethane delayed catalyst SA-1, tertiary amine delayed catalyst

NTCAT SA-1 is a tertiary amine low emission delay catalyst, especially recommended for use with low activity aliphatic isocyanate;

NTCAT SA-1 can strongly promote the reaction of urethane in microcellular foam, self-skin foam, coating, adhesive, sealant and elastomer under thermal activation. Its thermal activation temperature is generally 50-70 Within range

NTCAT SA-1 is also mainly used as an epoxy resin curing agent, and can also be used as an epoxy latent curing accelerator. NTCAT SA-1 is mainly used for light emitting diodes, coils, transformers, diodes, transistors, integrated circuits, casting and packaging promotion Agent and epoxy powder coating accelerator.

product description:

POLYCAT SA-1 catalyst is a polyurethane catalyst with thermal sensitivity and delayed reaction. Under the condition of room temperature, the activity of POLYCAT SA-1 catalyst is very low. When the heat is increased, the activity can be rapidly increased, which is close to the activity of metal salt catalysts.

In the conventional amine catalyst system, POLYCAT SA-1 has little effect on the early reaction rate and fluidity during the foaming process. It mainly acts on the late stage of the foam reaction, which can greatly accelerate the curing time and shorten the demoulding time.

The appearance of the product is light gray liquid with low viscosity and slight amine smell. It is easily soluble in water and soluble in most organic solvents. It is easy to absorb carbon dioxide and moisture in the air, so please close the lid tightly and store in a sealed condition.



POLYCAT SA-1 is recommended to be used together with other conventional catalysts. In the self-skinning system: it can shorten the demoulding time, improve the production efficiency and does not affect the early milky time; it can also act on 141B foaming, full water foaming and hard foam sheet In the system’s formula.


Storage and transportation:

It should be sealed and stored in a dry, cool and ventilated warehouse.



180KG/drum Storage: It is recommended to store in a dry and cool area with proper ventilation. After the original packaging, please fasten the packaging cover as soon as possible to prevent the water and other substances from mixing into the product and affecting its performance. Do not breathe dust, avoid skin and mucous membrane contact. Smoking, eating and drinking are prohibited in the workplace. After work, shower and change clothes.
