Dibutyltin dilaurate is registered under the REACH Regulation and is manufactured in and / or imported to the European Economic Area, at ≥ 100 to < 1 000 tonnes per annum. Dibutyltin dilaurate is used by consumers, in articles, by professional workers (widespread uses), in formulation or re-packing, at industrial sites and in manufacturing. Dibutyltin dilaurate is an organotin compound that is usually abbreviated to DBTL or DBTDL.  The colorless to yellowish liquid has an oily consistency, is extremely flammable and gives off a fatty acid-like smell.  Dibutyltin dilaurate is soluble in acetone, methanol or other organic solvents, but is practically insoluble in water. Dibutyltin dilaurate catalyzes esterification reactions, transesterification reactions and polycondensation reactions and has become the industry standard for coatings, adhesives, solvents and elastomers. Dibutyltin dilaurate is a versatile catalyst that can be used in various urethen crosslinking reaction and silanol condensation reactions. Dibutyltin dilaurate drives the addition of alcohols with isocyanates to accelerate and complete the formation of urethanes. Dibutyltin dilaurate is stable to hydrolysis but will hydrolyze in the presence of aqueous caustic at roomtemperature. Dibutyltin dilaurate is incorporated into the final product and does not require removal. Dibutyltin dilaurate is a liquid catalyst for ease of processing. Dibutyltin dilaurate is used to crosslink two-component urethane coating systems for automotive, industrial and refinish coatings. Dibutyltin dilaurate is used to crosslink RTV silicon systems for the caulk and sealants markets.

Dibutyltin Dilaurate as Catalyst for Silicones: Dibutyltin dilaurate is a universally applicable catalyst for the crosslinking of cold vulcanizing silicone rubbers and silane-modified polymers and is widely used: from “construction market” silicone for sealing tiles at home to industrial applications such as in the production of cables, cast resin systems or RTV sealants used in the automotive industry. Two modes of action are possible: the Dibutyltin Dilaurate catalyst supports the curing of room temperature crosslinking silicone rubbers.  Exposed to the air, the ambient humidity reacts with the tin compound and the silicone mass solidifies.  Dibutyltin dilaurate accelerates this reaction and provides better processing properties.  Alternatively used two-component silicones harden not only by contact with the humidity, but require a second reaction partner to be supplied. Dibutyltin dilaurate as a Catalyst for Polyurethane Systems: Another application of Dibutyltin dilaurate is the production of polyurethanes for a wide variety of end applications: hard foams, sealants, adhesives, paints and coatings or large floors. As an additive, Dibutyltin dilaurate accelerates the connection of the individual reaction partners in order to reduce the curing time. For example, Dibutyltin dilaurate is a common crosslinking catalyst that can be used for 2-component urethanes in the automotive industry or for other industrial applications, such as the coating of tanks, pipelines or floor coverings.  On silica adsorbed, Dibutyltin dilaurate is used in urethane-based powder coatings for areas that have to withstand high weather loads. Soft and solid PU foams are a standard solution for plastic molded parts that have to withstand loads in everyday life, such as seats or cladding.  Dibutyltin dilaurate is also a widely used gelling catalyst.  The application possibilities also include elastomers.

Together with dibutyltin dioctanoate, dibutyltin dilaurate is used as a catalyst for polyurethane production from isocyanates and diols. Dibutyltin dilaurate is also useful as a catalyst for transesterification and for the room temperature vulcanization of silicones. Dibutyltin dilaurate is also used as a stabilizer in polyvinyl chloride, vinyl ester resins, lacquers, and elastomers. Dibutyltin dilaurate is also added to animal feed to remove cecal worms, roundworms, and tapeworms in chickens and turkeys and to prevent or provide treatment against hexamitosis and coccidiosis. Dibutyltin dilaurate is used as a stabilizer (polyvinyl chloride resins, vinyl resins, lacquers, and elastomers), a catalyst for urethane and silicones, and a drug (anthelmintic and coccidiostat). Dibutyltin dilaurate is stabilizer for vinyl resins, lacquers, elastomers; catalyst for urethane and silicones. Dibutyltin dilaurate is stabilizer for polyvinyl chloride resins.  Dibutyltin dilaurate is catalyst for curing certain silicones.

Dibutyltin dilaurate is catalyst for the curing of room-temperature-vulcanized (RTV) silicone elastomers to produce flexible silicone rubbers used as sealing compounds, insulators, and in a wide variety of other applications. Dibutyltin dilaurate (DBTDL) is an organotin compound that is used as a catalyst. Dibutyltin dilaurate is a colourless oily liquid. In terms of Dibutyltin dilaurate structure, the molecule consists of two laurate groups attached to a dibutyltin(IV) center. The molecular geometry at tin is tetrahedral. Based on the crystal structure of the related bis(bromobenzoate), the carbonyl oxygen centers are weakly bonded to tin. Together with dibutyltin dioctanoate, Dibutyltin dilaurate is used as a catalyst for polyurethane production from isocyanates and diols. Dibutyltin dilaurate is also useful as a catalyst for transesterification and for the room temperature vulcanization of silicones. Dibutyltin dilaurate is also used as a stabilizer in PVC. Dibutyltin dilaurate can be used as PVC heat stabilizers, and Dibutyltin dilaurate is the earliest used varieties in organotin stabilizers, heat resistance is less than tributyltin maleate, but Dibutyltin dilaurate has excellent lubricity, weather resistance and transparency can be ok, and Dibutyltin dilaurate has good compatibility with plasticizers, non-blooming, non-sulfide pollution, no adverse effects on heat sealing and printability.  For Dibutyltin dilaurate is liquid at room temperature, so the dispersion in plastic is better than solid stabilizer. Dibutyltin dilaurate is mainly used in soft transparent products or semi-soft products, generally in an amount of 1-2%.  In hard products, Dibutyltin dilaurate can be used as lubricant, and when used with maleic acid organic tin or thiol-containing organic tin can improve the fluidity of the resin material.  Compared with other organic tin, the goods early color large will cause yellow discoloration. Dibutyltin dilaurate can also be used as catalysts of synthesizing polyurethane, the curing agents of silicone rubber.  In order to enhance the thermal stability, transparency, compatibility with resins, as well as improve the impact strength for hard products and Dibutyltin dilaurate other properties, now Dibutyltin dilaurate has developed a number of modified varieties.  Lauric acid and other fatty acids is generally added in the category of pure, the epoxy ester or other metal soap stabilizer is also added in.
