Manta CAT-CTHMTS Chelated Organotin Catalyst

Manta CAT-CTHMTS is a chelated organotin catalyst specifically engineered for Silane Modified Polymers (MS/STP) and RTV silicone systems. Developed using advanced coordination chemistry, it offers a significant leap in performance over standard organotin catalysts.

While its catalytic speed exceeds both Dibutyltin Dilaurate (DBTDL) and Dibutyltin Diacetate (DBTDA), Manta CAT-CTHMTS eliminates the pungent odor associated with acetate-based tins. Crucially, it provides excellent thermal stability, preventing “reversion” (softening) of the cured rubber even under high-temperature sealed conditions.

Performance equivalent to industry standard Nitto Kasei Neostann U-220.

Features

• Ultra-Fast Curing: Significantly reduces tack-free time and deep-cure time compared to DBTDL.
• Low Odor Profile: Overcomes the strong, pungent acidic smell of tin diacetate, improving the manufacturing environment.
• Superior Anti-Reversion: Cured products remain stable and do not revert to a liquid state when heated in a sealed environment.
• Excellent Stability: Maintains consistent catalytic activity during long-term storage of the finished sealant.
• Tin-Efficient: High activity allows for lower dosage levels while maintaining rapid reaction kinetics.

1. MS Polymer & STP Sealants (One-Component)

The premier choice for MS Polymer-based adhesives and sealants used in construction and automotive assembly. It provides the rapid “green strength” required for immediate handling and construction efficiency.

2. RTV-1 Silicone Sealants

Specifically suited for single-component room-temperature vulcanized (RTV) silicone rubbers. It ensures a fast, reliable cure without compromising the shelf stability of the unreacted sealant.

3. High-Performance 2K Polyurethane Coatings

Ideal for two-component (2K) PU cross-linked systems, including automotive refinish paints, high-gloss industrial topcoats, and heavy-duty protective coatings. It accelerates the isocyanate-hydroxyl reaction, allowing for faster dust-free and tape-free times.

4. Sealed High-Temp Applications

Recommended for gaskets, engine sealants, and industrial bonding where the cured material will be exposed to heat in a confined space.
