Dibutyltin plasticiser complex refers to a group of organotin compounds where dibutyltin is complexed with plasticizers, enhancing its solubility and processing characteristics.
Dibutyltin plasticiser complex is a liquid version of dibutyltin oxide (DBTO) containing a non-phthalate-based plasticizer.

Dibutyltin plasticiser complex contains 35% of the active tin content compared to the solid version of DBTO, REAXIS® C248.
Other liquid versions using phthalates as the diluent include REAXIS C248D, which includes a plasticizer and a relatively high tin content, and REAXIS C248DP, which contains a plasticizer and lower tin content.

Liquid versions of DBTO-based silanes include REAXIS C248T, which contains a silane complex, and REAXIS C248VM, which is another variant of DBTO and silane compound.
Dibutyltin plasticiser complex is a dialkyl organotin typically used as an esterification catalyst.

Commonly referred to as DBTO or Dibutyloxotin, Dibutyltin plasticiser complex is characterized by a high tin content (~48%) and oxide ligand which imparts both high reactivity and high-temperature stability.
Dibutyltin plasticiser complex is supplied as a solid and can be supplied as a stable liquid with suitable diluents such as plasticizers and silanes.

Related liquid-grade versions of Dibutyltin Oxide include Dibutyltin plasticiser complex, which includes a plasticizer and a relatively high tin content, REAXIS C248DP, which contains a plasticizer and lower tin content, Dibutyltin plasticiser complex, which also contains a plasticizer but has a lower overall tin volume, REAXIS C248T, which contains a silane complex, and REAXIS C248VM, which is another variant of DBTO and silane compound.

These liquid versions of Dibutyltin plasticiser complex are used as catalysts for silicone condensation reactions.
Dibutyltin plasticiser complex is a solid-grade version with improved particle size distribution and lower chloride content.
Dibutyltin plasticiser complex is an organotin compound.

The amorphous, granular white powder, Dibutyltin plasticiser complex, is very difficult to dissolve in organic solvents or in water.
Dibutyltin plasticiser complex has a strong smell, but is not corrosive and neutral in the product, so no separation is required after the reaction has ended.

USES and APPLICATIONS of DIBUTYLTIN PLASTICISER COMPLEX:
Dibutyltin plasticiser complex is an extremely versatile chemical.
Previously described characteristics make Dibutyltin plasticiser complex interesting for dyes and the manufacture of pharmaceuticals.
However, Dibutyltin plasticiser complex not only has catalyzing properties, but stabilizing ones as well, which is why it is used as a PVC stabilizer.

Dibutyltin plasticiser complex increases resistance to hydrolysis and the thermal stability of the plastic.
There are also food-approved Dibutyltin plasticiser complex-containing products used for products that come into contact with food.
Dibutyltin plasticiser complex is utilized in various industrial processes.

Catalyst in Esterification and Transesterification Reactions: Dibutyltin plasticiser complex facilitates the synthesis of esters, including plasticizers and lubricant esters.
Polyurethane Production: Dibutyltin plasticiser complex acts as a catalyst in the production of polyurethane foams, coatings, and adhesives.

Silicone Curing: Dibutyltin plasticiser complex is used in the curing of silicone-based systems, enhancing crosslinking efficiency.
Stabilizer in PVC Processing: Dibutyltin plasticiser complex improves thermal stability and processing characteristics of PVC.
Dibutyltin plasticiser complex is widely used as catalysts and stabilizers in various industrial applications.

Dibutyltin plasticiser complex is used as a versatile catalyst and stabilizer.
The broadest applications of Dibutyltin plasticiser complex are found in esterification reactions and transesterification reactions, such as in the transesterification of natural fatty acids, aminocarboxylic acids and in regioselective tosylation.
The catalytic properties of Dibutyltin plasticiser complex are also used in condensation reactions, for example silanol condensation.

-Dibutyltin plasticiser complex uses as a Binder Catalyst:
In addition to paints and coatings, Dibutyltin plasticiser complex is used as a binder with a wide variety of end-uses.
For alkyd resins, Dibutyltin plasticiser complex is a catalyst with a wide range of applications (among others for non-drying, long-oil alkyd as a polymeric plasticizer).

Polycarbonates, silicones and polyurethane foams are also among the fields of application.
Dibutyltin plasticiser complex is also used for various polyester resins.

As a binder Dibutyltin plasticiser complex catalyzes unsaturated polyester systems needed in glass fiber reinforced plastics, carbon fibers or laminates.
Another example are casting resins for the insulation of electronic components.

-Dibutyltin plasticiser complex is used in Oleochemistry:
Dibutyltin plasticiser complex is used as a liquid, very active catalyst for esterification: in plasticizers, for lubricant esters, surfactants and for fatty acid esters.

Dibutyltin plasticiser complex can be used just as widely in the catalysis of transesterification reactions as in regioselective alkylation, sulfonation and acylation, even if alcohol groups are contained in the starting material.

PAINTS AND COATINGS USES OF DIBUTYLTIN PLASTICISER COMPLEX:
The catalytic properties of Dibutyltin plasticiser complex are used for various paints and coatings, most notably for cathodic electrodeposition.
Dibutyltin plasticiser complex is considered “the” standard catalyst for crosslinking in cathodic electrocoating.

In the course of the process, an approx. 20 µm thick primer is applied to the surface of the components to protect them from corrosion and physical damage.

Other areas in which Dibutyltin plasticiser complex is used as a curing catalyst include water-based polyurethane coatings, silicone-based systems, polyester resins and alkyd resins, where it has proven its worth as a catalyst for high-temperature transesterification reactions as required in the production of powder coating materials and alkyd resins.

Dibutyltin plasticiser complex is also employed in widely used paints (oil paints and varnishes).
Coatings, to which Dibutyltin plasticiser complex is added as a process additive, can be used in many everyday products, to whose protection and durability they contribute.

In the automotive industry, car bodies and other components are coated that have to withstand environmental influences.
Sports equipment, such as ski poles or boat masts, are also coated, some of which withstand highly corrosive weather conditions.

Dibutyltin plasticiser complex is also used in the construction of chemical apparatus (cooling towers, tanks, etc.).
The hardening accelerating effect of the catalyst is also used for many floor coatings.
