Anti-Hydrolysis Organotin Catalyst TCAT-S032 Equivalent To Formez UL-32, Niax LC-5632

TCAT-S032 is a highly effective, hydrolysis-resistant organotin catalyst explicitly developed to overcome the degradation issues of conventional organometallic catalysts. Standard catalysts typically lose chemical activity when formulated into systems containing trace moisture, acids, or alkalis. TCAT-S032 offers excellent long-term storage stability in these challenging environments and serves as a direct high-performance alternative to imported benchmarks such as Fomrez UL-32 and Niax LC-5632.

• High Catalytic Activity: Functions as a powerful gelling catalyst. It exhibits significantly stronger low-temperature catalytic activity than standard dibutyltin dilaurate (DBTDL / T-12).
• Excellent Gelling Optimization: Formulated for polyurethane (PU) foam applications. When paired with amine co-catalysts, it establishes an optimal gelling-foaming balance, enhances post-curing kinetics, guarantees a smooth reaction profile, and effectively prevents shrinking or foam collapse.
• Superior Hydrolysis Resistance: Allows for early premixing into water-containing components (B-side system). It provides a considerably extended storage shelf-life and steadier process consistency compared to standard DBTDL (T-12) formulas.

• Polyurethane CASE Applications: Coatings, Adhesives, Sealants, and Elastomers.
• Polyurethane Foam Systems: Highly stable, dependable gelling catalyst providing superior chemical storage integrity when pre-blended directly into polyol blend configurations.

• General Loading Level: Typically used at 0.03% to 0.3% by weight of total Polyurethane (PU) formulation mass.
• Two-Component Systems: Typically dosed at 0.05% to 0.5% based on total Polyol component weight.
• Foam Production: Suitable for direct premixing into water-laden compounded polyol blends.
• Handling Precautions: Containers must be kept tightly closed at all times. Reseal immediately after each use to eliminate ambient exposure.

• Packaging Option: Available in High-Density Polyethylene (HDPE) plastic drums containing 25 kg or 200 kg net weight.
• Storage Environment: Store within a cool, dry warehouse environment. Ensure the storage area provides reliable protection against direct sunlight exposure and rainwater infiltration.
• Shelf Life: Unopened packaging maintains full chemical integrity for 24 months from production date. Materials exceeding this time frame may still be utilized if catalytic activity levels fulfill original parameters.
