Uses:

Used in organic synthesis.

Stannous isooctanoate is a white or light yellowish brown paste, sometimes called stannous octanoate. It is soluble in petroleum ether and insoluble in water. It is a basic catalyst for the production of polyurethane foam, mainly used in the gelation reaction in the foaming of polyether-polyurethane, and can also be used as a polyurethane foam antioxidant. Used as catalyst for polyurethane synthesis and room temperature vulcanization of silicone rubber. Also used as catalyst type curing agent for epoxy resin. Stannous octanoate has greater catalytic activity than dibutyltin dilaurate in curing, and if the two are used in combination, the effect is better than that of using them individually, and it can take into account the speed of reaction and curing. Since dibutyltin compounds are easily oxidized and decomposed by oxygen and water vapor in the air, they should be used for nitrogen protection when stored, and must be sealed, avoiding high temperature and excessive humidity, in order to prevent the activity from decreasing or failing.

The nature of the complex is very unstable, once the urethane bond is generated, it will be free, which is conducive to further catalyzing, triethylenediamine has a strong catalytic effect on the gel reaction and foaming reaction, especially on the polyurethane and hydroxyl catalytic effect is more selective.A33 is mainly used as gel catalyst for polyurethane foams, and it is widely used in flexible, semi-rigid, rigid polyurethane foams, elastomers, coatings, etc.

Content 33% Triethylene diamine solution

Form Solid

Application Flexible, semi-rigid, rigid urethane foam

Chemical composition:

33% solution of triethylenediamine.

Triethylenediamine is solid at room temperature and is not convenient for use as a polyurethane catalyst. In industrial applications, it is often melted in small molecule diols and configured to be used as an alcohol solution with a mass fraction of 33% (or other concentrations).

Commonly used diols are dipropylene glycol monoacetate, propylene glycol, diethylene glycol monoacetate (diethylene glycol), ethylene glycol and so on.
