|Name||DOTL Dioctyltin Dilaurate|
Stannanes, dioctylbis[(1-oxododecyl) oxy]
In a variety of urethane crosslinking reactions dioctyltin dilaurate can be used as a catalyst to influence the duration of the process. DOTL has a lower toxicity compared to alternative additives, which offers advantages in handling, and is considered one of the standard catalysts in this field.
Examples of end-use applications include adhesives and sealants, foams and polyurethane casting resin systems required for floors and other applications where high physical loads are expected. Paints, powder coatings and coating systems can also be dioctyltin dilaurate-catalyzed.
Similar to polyurethane-based materials, DOTL is also known as one of the standard catalysts for silicones and silane-modified polymers and is characterized by its relatively low toxicity. RTV silicones for automotive applications and molding compounds are examples of applications.
Due to its broad profile and comparatively low toxicity, dioctyltin dilaurate catalysts are also used in a wide range of applications beyond polyurethanes and silicones, for example for binders such as alkyd resins, as polymerization initiators for formaldehydes or in silanol condensation reactions. DOTL is also an important intermediate product within the chemical industry.
In addition to its catalytic activity, dioctyltin dilaurate is also effective as a stabilizer and provides significantly improved light stability in PVC plastics.
Various dioctyltin dilaurate variants with different degrees of purity are available from BNT, tailor-made specifications are available on request.
