Addocat SO is a function Catalyst for the production of polyurethanes, e.g. polyether and polyester flexible slabstock foam, hot molded foam, rigid spray foam, 2 C-paints and coatings as well as other polyurethane applications.
Appearance of Addocat SO:
Clear, slightly yellowish liquid.
Solubility:
Not miscible with water, hydrolyses.
Synonyms:
Stannous-II-ethylhexanoate
Stannous-II-octoate
Addocat SO is stannous (II) ethylhexanoate.
Addocat SO acts as a catalyst for the production of polyurethanes, e.g. polyether and polyester flexible slabstock foam, hot molded foam, rigid spray foam.
Addocat SO catalyzes mainly the crosslinking reaction of the polyol and isocyanates.
Addocat SO recommended dosage is between 0.03 and 0.5 p.b.w.
Addocat SO has a shelf life of 12 months.
Addocat SO is a polyurethane catalyst based on an organic metal compound, specifically Stannous Octoate.
Addocat SO activates the gelling (crosslinking) reaction in polyether- and polyester-based polyurethane flexible slabstock foam, hot molded foam, rigid spray foam, 2K polyurethane coatings and other polyurethane applications.
Typical Properties of Addocat SO:
Property / Nominal Value / Unit
Density at 20 °C / approx. 1.23 - 1.27 / g/cm³
Flash point / approx. 130 / °C
Initial boiling point / > 200 / °C
Pour point / < -20 / °C
Refractive index / 1.4830 - 1.5030 / #
Tin (II) content / min. 27.0 / %
Tin content (total) / min. 28.0 / %
Viscosity at 20 °C / approx. 350 / mPa·s
Applications of Addocat SO:
Addocat SO catalyses mainly the crosslinking reaction of the polyol and the isocyanate.
In the production of PUR ether and ester foam Addocat SO is metered separately.
As well as having other advantages, this enables an equilibrium of the crosslinking and blowing reactions to be maintained during production.
Typical dosage of Addocat SO is between 0.03 and 0.5 pphp.
The accuracy of metering can be improved if Addocat SO is mixed with other components at a ratio suitable to the capacity of the metering pump, e. g. with polymeric plasticizers that do not affect the polyurethane reaction or with polyether polyols based on propyleneoxide, but without ethylene oxide.
The mixing ratio applicable to these examples is usually 1 : 4 or 1 : 9.
