Features Of Shepherd BiCAT Z Bismuth Catalyst

  1. Non-toxic bismuth-based alternative to traditional tin and mercury catalysts.

  2. Excellent selectivity in polyurethane foam and elastomer synthesis with minimal side reactions.

  3. Thermally stable up to 180 °C, supporting high-temperature processing without premature decomposition.

  4. Compatible with a broad range of polyols, isocyanates, and blowing agents including water and physical foaming agents.

  5. Low volatility and negligible odor—enhancing workplace safety and reducing VOC emissions.

Typical Applications Of Shepherd BiCAT Z Bismuth Catalyst

  1. Flexible and rigid polyurethane foams for automotive seating and insulation panels.

  2. Castable polyurethane elastomers used in industrial rollers, mining screens, and wear-resistant parts.

  3. Coatings and adhesives requiring low-cure-temperature reactivity and long pot life.

  4. One-component moisture-curing sealants and caulks for construction and automotive assembly.

  5. Microcellular urethane foams for gasketing, damping, and acoustic applications.
