Equivalent To Fomrez UL-32 Alternative - Transparent Liquid
TCAT-S032 is a highly effective, hydrolysis-resistant organotin catalyst specifically engineered to overcome degradation issues common in conventional organometallic catalysts. Unlike standard catalysts that lose chemical activity when exposed to trace moisture, acids, or alkalis, TCAT-S032 maintains excellent long-term storage stability in challenging environments.
This powerful gelling catalyst demonstrates significantly stronger low-temperature catalytic activity than standard dibutyltin dilaurate (DBTDL / T-12), ensuring fast cure kinetics, smooth reaction profiles, and trouble-free processing across diverse polyurethane formulations.

Performance Characteristics & Key Benefits
High Catalytic Activity
Functions as a powerful gelling catalyst with significantly stronger low-temperature catalytic activity than standard dibutyltin dilaurate (DBTDL / T-12), enabling faster production cycles.
Excellent Gelling Optimization
When paired with amine co-catalysts, establishes optimal gelling-foaming balance, enhances post-curing kinetics, guarantees smooth reaction profiles, and prevents shrinking or foam collapse.
Superior Hydrolysis Resistance
Allows early premixing into water-containing components (B-side system). Provides considerably extended storage shelf-life and steadier process consistency compared to standard DBTDL formulas.
Import Benchmark Replacement
Direct high-performance alternative to Fomrez UL-32 and Niax LC-5632, offering equivalent or superior catalytic performance at a competitive cost structure.
Primary Application Fields
PU Additives & CASE Applications
Highly effective as a polyurethane additive for Coatings, Adhesives, Sealants, and Elastomers – delivering consistent gelling catalysis with exceptional pot life stability and moisture tolerance.
Polyurethane Foam Systems
Highly stable, dependable gelling catalyst providing superior chemical storage integrity when pre-blended directly into polyol blend configurations containing water or other active hydrogen compounds.

Handling Precautions: Containers must be kept tightly closed at all times. Reseal immediately after each use to eliminate ambient moisture exposure. Avoid prolonged contact with humid air to maintain catalytic activity.
Packaging, Storage & Shelf Life
Packaging
Available in High-Density Polyethylene (HDPE) plastic drums containing 25 kg or 200 kg net weight. Custom packaging options available upon request.
Storage
Store in a cool, dry warehouse environment with reliable protection against direct sunlight exposure and rainwater infiltration. Keep containers tightly sealed.
Shelf Life
24 months from production date in unopened original packaging. Materials exceeding this time frame may still be utilized if catalytic activity levels fulfill original parameters.
Transportation
Non-dangerous goods under standard transport regulations. Protect from moisture and direct sunlight during transit.
