Manta CAT-CTHMTS is a chelated organotin catalyst specifically engineered for Silane Modified Polymers (MS/STP) and RTV silicone systems.
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
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.
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.
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.
Recommended for gaskets, engine sealants, and industrial bonding where the cured material will be exposed to heat in a confined space.
Application Areas
Packaging
Available in 25kg steel-plastic composite pails or 200kg drums.
Safety and Storage
Moisture Sensitivity (CRITICAL): Manta CAT-CTHMTS reacts aggressively with moisture. Avoid all contact with water. Containers must be tightly sealed and ideally purged with dry nitrogen after each use.
Storage: Store in a cool, dry warehouse. If the product solidifies during winter (due to its 15-30°C melting point), it should be gently warmed and homogenized before use.
Safety: Avoid contact with skin and mucous membranes. In case of contact, flush immediately with large amounts of water.
