Amine 33 (A-33) is a highly active tertiary amine catalyst composed of 33% triethylene diamine and 67% dipropylene glycol. It appears as a colorless to amber liquid and is widely used in polyurethane (PU) systems to accelerate the foaming and curing reactions. It is suitable for flexible, rigid, microporous, and high-resilience foams, as well as coatings and CASE applications (Coatings, Adhesives, Sealants, and Elastomers).

Key Features:

• Enhances Urethane Reaction – Improves reactivity between polyols and isocyanates for efficient foam formation
• Low Emission Performance – Suitable for environmentally friendly, low-VOC PU systems
• Excellent System Compatibility – Does not adversely affect foam hardness, elongation, or compression properties
• High Catalytic Efficiency – Supports uniform cell structure and consistent foam quality

Applications:

Amine 33 is widely used in:

• Flexible polyurethane foams
• Rigid polyurethane foams
• High-resilience (HR) foams
• Microporous foam systems
• PU coatings and CASE applications (adhesives, sealants, elastomers)

Safety Instructions:

• Avoid inhalation of vapors, mists, or aerosols
• In case of eye or skin contact, rinse immediately with plenty of water and seek medical advice if necessary
• If ingested, rinse mouth thoroughly and obtain medical attention immediately
• Always use appropriate personal protective equipment (PPE) and refer to the Safety Data Sheet (SDS) before handling

Handling & Storage:

• Store in tightly sealed containers in a cool, dry, and well-ventilated area
• Protect from heat, moisture, direct sunlight, and contamination
• Follow standard industrial hygiene practices during handling
• In case of spillage, absorb using inert material and dispose of according to local regulations. Prevent entry into water systems or drains
• This catalyst ensures efficient processing, improved foam structure, and consistent performance across a wide range of polyurethane applications.
