What is Dibutyltin dilaurate?

Chemical properties

yellow liquid

The Uses of Dibutyltin dilaurate

PU catalyst, RTV silicone rubber

The Uses of Dibutyltin dilaurate

Stabilizer for polyvinyl chloride resins. Catalyst for curing certain silicones.

The Uses of Dibutyltin dilaurate

Dibutyltin dilaurate has been used as a catalyst in a protocol for the covalent attachment of poly(ethylene glycol) (PEG) to silicon oxide to form a hydrophilic non-fouling surface. It can also be used as a catalyst in the preparation of polymers by reacting hydroxyl-terminated macromonomers and aliphatic diisocyanates.

The Uses of Dibutyltin dilaurate

Di-n-butyltin dilaurate is used as a catalyst for the production of polyurethanes as well as for the transesterification reactions. It is involved in the vulcanization of silicones and a stabilizer in polyvinyl chloride (PVC). It acts as a rust inhibitor for polyurethanes, polyols, silicones and as a fuel additive.

General Description

Clear yellow viscous liquid.

Air & Water Reactions

Dibutyltin dilaurate may be sensitive to air or heat. . Insoluble in water.

Reactivity Profile

Dibutyltin dilaurate is strongly reactive with many other groups. Incompatible with acids and bases. Organometallics are good reducing agents and therefore incompatible with oxidizing agents.

Fire Hazard

Dibutyltin dilaurate is combustible.

Safety Profile

Poison by ingestion and intraperitoneal routes. A skin and eye irritant. Avoid the vapor produced by heating. Combustible when exposed to heat or flame; reacts with oxidizers. When heated to decomposition it emits acrid smoke and fumes. See also TIN COMPOUNDS
