Amine Catalyst A-33 is commonly used in:
- Flexible slabstock polyurethane foam
- Molded polyurethane foam
- Automotive seating and interior components
- Mattresses and bedding
- Furniture cushions
- Integral skin foam
- High-resilience (HR) foam
- Specialty polyurethane systems
Key Benefits
- Promotes balanced blowing and gelling reactions
- Improves foam rise and flow characteristics
- Produces uniform and consistent cell structure
- Enhances foam stability and dimensional accuracy
- Reduces curing time for increased production efficiency
- Delivers consistent processing performance
- Compatible with a wide variety of polyurethane formulations
How to Use
Amine Catalyst A-33 is added to the polyol blend during polyurethane formulation before mixing with the isocyanate component. The recommended dosage varies depending on the foam formulation, density, and desired reaction profile. It is often used alongside silicone surfactants and other catalysts to achieve the required foam characteristics.
Storage & Handling
Store in tightly sealed original containers in a cool, dry, and well-ventilated area away from direct sunlight and sources of ignition. Avoid contact with skin and eyes, and wear appropriate personal protective equipment (PPE) during handling. Refer to the Safety Data Sheet (SDS) before use.
