Amine 33 (A-33) is a highly active, tertiary amine catalyst composed of 33% triethylene diamine and 67% dipropylene glycol. This colorless to amber liquid is widely used in the production of polyurethane (PU) foams, especially flexible, rigid, microporous, and high-resilience foams, as well as coatings and CASE applications.

Key Features

• Promotes Urethane Reaction: Enhances polyol-isocyanate reactivity in foam systems.
• Low Emission Profile: Ideal for eco-friendly, low-VOC polyurethane foam production.
• Excellent Compatibility: Does not impact foam elongation, compression, or hardness.
• High Activity: Supports uniform foam quality and improved physical properties.

Applications

• A-33 is ideal for use in:
• Flexible PU foams
• Rigid PU foams
• High-resilience foams
• Microporous foams
• PU coatings and CASE systems

Safety Instructions

• Avoid inhalation of vapors and mists.
• Upon eye or skin contact, wash with water promptly and seek medical guidance.
• If ingested, rinse mouth thoroughly and consult a physician.
• Always wear appropriate protective clothing and consult the product’s MSDS before use.

Handling & Storage

• Store in sealed containers away from heat, moisture, and direct sunlight in a ventilated area.
• Avoid exposure to any foreign substance, sunlight and humidity
• Follow proper industrial hygiene practices during handling.
• In case of any spillage, absorb with inert material and dispose of according to local regulations. Prevent release into water systems.
