July 4, 2023by admin0

NT CAT A-239 is a tertiary amine catalyst used in the production of polyurethane foams. It is a clear, colorless liquid with a mild odor. NT CAT A-239 is miscible with water, alcohols, and ketones. NT CAT A-239 has a flash point of 100 °F (38 °C) and a vapor pressure of 0.1 mmHg at 25 °C. NT CAT A-239 is stable under normal conditions.

NT CAT A-239 is a safe and effective catalyst for polyurethane foam production. Always follow the manufacturer’s instructions when using NT CAT A-239 to ensure safe and effective use.

Here is some additional information about NT CAT A-239:

· NT CAT A-239 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.

· NT CAT A-239 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.

· NT CAT A-239 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.

· NT CAT A-239 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 NT CAT A-239, consult the manufacturer’s safety data sheet or contact a qualified professional.
