Use of Tin(II) 2-ethylhexanoate

Tin(II) 2-ethylhexanoate can be used as a catalyst in systems based on polyurethanes or silicone resins. The addition of the tin compound leads to reduced curing times. In addition, the compound can be used as a cocatalyst together with amino catalysts to control the blowing reaction.

Thanks to their high activity, tin(II) 2-ethylhexanoate catalysts are used extensively in a verity of adhesives and sealants as well as varnishes and coatings. Tin(II)-octoate impregnated silica in urethane powders are used for powder coating, the resulting coatings being resistant to harsh weather conditions.

It has application as a gelling agent in the production of flexible polyurethane block foam acting as a catalyst. In addition, tin(II)-2-ethylhexanoate catalyzes esterification reactions and show a high activity.

In silicone chemistry, tin(II) 2-ethylhexanoate catalyzes silanol condensation reactions to produce RTV silicones, which are mainly used as sealants in the automotive sector or similar applications.

The substance is generally used as a process additive, lubricant or stabilizer for transformer oils. It is currently used as a catalyst for the polymerization of polylactides.

Transport and Storage

Tin(II) 2-ethylhexanoate is available in various packaging units and can be stored in its sealed original packaging for at least 6 months without loss of quality. However, both high heat and below 0 °C temperatures should be avoided.
