Delayed Catalyst SA-1


Name: Delayed Catalyst SA-1

Alias: Delayed Catalyst SA-1, 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 catalyst with low emission delay, especially recommended for use with low activity aliphatic isocyanate;

NTCAT SA-1 can strongly promote microcellular foams, self-skin foams, coatings, adhesives, sealants and elastomers under thermal activation For the reaction of carbamate, the thermal activation temperature is generally in the range of 50-70;

NTCAT SA-1 is also mainly used as a curing agent for epoxy resins, and it can also be used as a latent curing accelerator for epoxy. NTCAT SA-1 is mainly used for light-emitting diodes. Coils, transformers, diodes, triodes, integrated circuits, casting and packaging accelerators and epoxy powder coating accelerators.

Product description:

SA-1 catalyst is a heat-sensitive polyurethane catalyst that delays the reaction. At room temperature, the activity of SA-1 catalyst is very low, and under the condition of increased heat, the activity can be increased rapidly, which is close to the activity of metal salt catalysts.

In the conventional amine catalyst system, SA-1 has little effect on the initial reaction rate and fluidity during the foaming process, and it mainly acts in the late stage of the foam reaction. , Can greatly accelerate the curing time, thereby shortening the demolding time.

The appearance of this product is light gray liquid, low viscosity, slight amine odor, 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 it in a sealed condition.

SA-1 is recommended to be used together with other conventional catalysts. In the self-skinning system: it can shorten the demolding time, improve the production efficiency and does not affect the early milking time; also It can be used in the formulation of 141B foaming, full water foaming and rigid foam board system.
