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.

Product Usage:
The active ingredient of polyurethane catalyst A33 is triethylene diamine, the solution prepared by 33% of triethylene diamine and 67% of monoconjugated dipropylene glycol is mainly used as gel catalyst for polyurethane foam, which is widely used in flexible, semi-rigid, rigid polyurethane foam, coating, elastomer, In polyurethane foaming system, isocyanate firstly reacts with triethylene diamine to generate active complex. 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.

Mon, 17 Apr 2023 06:05:51 +0000http://m.gengheonline.cn/archives/42887Niax A33 is a tertiary amine used as a catalyst in the production of polyurethane foam. It is a clear amber liquid with a specific gravity of 0.92 and a boiling point of 180 degrees Celsius. Niax A33 effectively catalyzes the reaction between isocyanates and hydroxyl groups, a key step in polyurethane formation. Amines are also used to control end product properties such as hardness, flexibility and water resistance.
Niax A33 is often used in combination with other catalysts such as tin catalysts and metal carboxylates. The choice of catalyst system will depend on the desired properties of the final product.
Niax A33 is a safe and effective catalyst for the production of polyurethane foam. Always follow the manufacturer’s instructions when using this product.
Here are some safety precautions you should take when using the Niax A33:
Wear gloves and goggles when handling this product.
Avoid contact with skin and eyes.
In case of contact, flush with water for 15 minutes and seek medical attention.
Store in a cool, dry place.
Keep out of reach of children and pets.
Niax A33 may be hazardous if used incorrectly. It is very important to read and follow the manufacturer’s instructions carefully.
Here are some properties of the Niax A33:
It is a clear amber liquid.
