Chemical Properties Of Dibutyltin dilaurate

Dibutyltin dilaurate (DBTDL) is an organotin additive, MF: C32H64O4Sn, MW: 631.56. It is typically produced by esterification of dibutyltin oxide with lauric acid under specific conditions. At room temperature, it appears as a pale yellow or colorless oily liquid, solidifying into white crystals at low temperatures. The Sn-O bond in its molecule exhibits high reactivity, enabling it to catalyze ester exchange and condensation reactions, forming the chemical foundation for its core applications.

Product Application Of Dibutyltin dilaurate

  1.  Dibutyltin dilaurate serves as a highly effective catalyst for polyurethane foams (rigid and flexible), polyurethane elastomers, polyurethane adhesives, and sealants.
  2. Dibutyl tin dilaurate serves as an auxiliary heat stabilizer for polyolefin materials like PVC. When blended with calcium-zinc stabilizers, it enhances thermal stability and weather resistance of PVC products while reducing degradation and yellowing during processing. Commonly used in PVC hoses, electrical cable jackets, and similar products.
  3.  Catalyzes the curing of unsaturated polyester resins and acrylic resins, as well as ester exchange reactions in polyester coatings. Shortens coating curing time while improving film adhesion and hardness. Suitable for industrial anti-corrosion coatings, wood coatings, and similar applications.
  4. Dibutyltin dilaurate also serves as a catalyst for silicone rubber crosslinking reactions in the production of room-temperature vulcanized silicone rubber, and as a crosslinking accelerator for fabric waterproofing finishes.
