Features Of Baerlocher BAEROPAN KK 477 Liquid Potassium Zinc Blowing Catalyst Stabilizer

  1. Highly effective liquid-phase catalyst stabilizer for potassium-based blowing agents in rigid polyurethane foam systems.

  2. Prevents premature decomposition and catalytic deactivation during storage and processing, ensuring consistent foam rise performance.

  3. Enables precise control of cream time and gel time without compromising dimensional stability or cell structure.

  4. Compatible with common polyols, isocyanates, and auxiliary additives—including amine and tin catalysts—without phase separation.

  5. Non-volatile, low-odor formulation supports safer handling and improved workplace air quality versus traditional metal soaps.

Typical Applications Of Baerlocher BAEROPAN KK 477 Liquid Potassium Zinc Blowing Catalyst Stabilizer

  1. Rigid polyurethane (PUR) insulation foams for building envelope and refrigeration panels.

  2. Structural insulated panels (SIPs) requiring uniform density distribution and closed-cell integrity.

  3. Continuous lamination lines where consistent pot life and flow behavior are critical for high-speed production.

  4. Low-emission appliance foams meeting stringent VOC and fogging specifications (e.g., OEM automotive and white goods).
