For formulators and chemists working with polyurethanes and other polymer systems, a thorough understanding of the chemical properties and specifications of catalysts like Stannous Octoate is fundamental to achieving desired results. NINGBO INNO PHARMCHEM CO.,LTD. provides key details regarding the composition and characteristics of this vital organometallic compound.

Stannous Octoate, also known by its chemical name Tin(II) 2-ethylhexanoate or Tin(II) octoate, has the molecular formula C16H30O4Sn. A key specification is its tin content, typically expressed as a percentage by weight. Manufacturers usually provide a guaranteed minimum tin content, often around 28.0% or higher, with a specific range for the stannous (Sn(II)) tin content to ensure optimal catalytic activity. For instance, a common specification might be a stannous content between 27.25% and 29%. These precise figures are critical for accurate dosing in formulations.

The physical appearance of Stannous Octoate is generally described as a light yellow, colorless, or pale yellow liquid. Its viscosity, measured at 25°C, is another important parameter, often specified to be below a certain limit (e.g., <380 mPa·s) to ensure ease of handling and mixing. The refractive index, typically around 1.49, serves as a purity indicator. Importantly, Stannous Octoate is soluble in most organic solvents and polyols, which facilitates its integration into various chemical processes, but it is largely insoluble in water and degrades upon contact with it.

Understanding these stannous octoate properties is essential for predicting its behavior in a reaction system. NINGBO INNO PHARMCHEM CO.,LTD. ensures that its Stannous Octoate products meet these critical specifications, providing formulators with a reliable component for their manufacturing needs. Whether developing new polyurethane formulations or optimizing existing ones, precise knowledge of the catalyst's attributes, including its chemical specifications for stannous octoate, is key to success.
