Dabco 2039 is a tertiary amine catalyst used in the production of polyurethane foams. It is a clear, colorless liquid with a mild odor. Dabco 2039 is miscible with water, alcohols, and ketones. Dabco 2039 has a flash point of 100 °F (38 °C) and a vapor pressure of 0.1 mmHg at 25 °C. Dabco 2039 is stable under normal conditions.

Dabco 2039 is a safe and effective catalyst for polyurethane foam production. Always follow the manufacturer’s instructions when using Dabco 2039 to ensure safe and effective use.

Here is some additional information about Dabco 2039:

· Dabco 2039 is a tertiary amine. A tertiary amine is an organic compound containing three nitrogen atoms. Tertiary amines are often used as catalysts in chemical reactions.

· Dabco 2039 is a balanced catalyst. This means that it promotes the urethane and urea reactions in polyurethane foams. This results in the foam having good properties, such as strength, flexibility, and water resistance.

· Dabco 2039 is a highly efficient catalyst. This means that it requires less catalyst to create foam than other catalysts. This saves money and reduces the environmental impact.

· Dabco 2039 has a wide range of processing options. This means that it can be used in a variety of polyurethane systems. This makes it a versatile catalyst that can be used to produce a variety of foams.

If you have any further questions about Dabco 2039, consult the manufacturer’s safety data sheet or contact a qualified professional.
