Overview
Butyltin tris(2-ethylhexanoate)丨CAS 23850-94-4 is an organotin compound widely used in industrial and chemical applications. It belongs to the class of organotin carboxylates, characterized by tin atoms bonded to organic groups and carboxylate ligands-in this case, 2-ethylhexanoate.
Applications
Catalyst in Polymerization
Serves as an effective catalyst in the production of polyurethanes and silicone polymers.
Enhances polymer cross-linking and curing rates, improving production efficiency and material properties.
Stabilizer in PVC Processing
Acts as a heat stabilizer in the manufacture of polyvinyl chloride (PVC) products.
Prevents degradation during processing by scavenging hydrochloric acid (HCl) released when PVC is heated, thus extending the polymer's lifespan and maintaining mechanical properties.
Biocide and Antifouling Agent
Used as an antifouling agent in marine coatings to inhibit the growth of barnacles, algae, and other aquatic organisms on ship hulls and underwater structures.
Provides long-term protection against biofouling, which improves vessel efficiency and reduces maintenance costs.
Catalyst in Polyester and Alkyd Resin Production
Facilitates the esterification and polycondensation reactions in the manufacture of polyester resins and alkyd resins.
Helps control molecular weight and resin properties, ensuring desirable durability and finish in paints and coatings.
Additive in Coatings and Paints
Incorporated in paints and coatings as a drying agent and stabilizer.
Enhances curing speed and improves final film toughness and adhesion.
Benefits
High Catalytic Efficiency
Butyltin tris(2-ethylhexanoate)丨CAS 23850-94-4 offers strong catalytic activity, allowing for faster reaction times and improved product quality in polymer and resin manufacturing.
