Features & Benefits
- CASE Ingredients Features
- Features
- Stabilized tin octoate with a metal content of approx. 28 % by weight, soluble in most organic solvent
- Accelerates the reaction between the polyol and isocyanate component of polyurethane foam systems
- Ensures fast blocking stability
- Earlier solvent resistance and sanding capability
- Higher film hardness
- Enables control of the foaming characteristics resulting in more homogeneous foam with improved resistance to heat and oxidational degradation

- Dosage
- For polyurethane coating systems, an addition rate of Borchi® Kat 28 between 0.01 and 0.03 % product, calculated on solid binder is recommended, depending on the used binder and formulation. The exact amount has to be determined in preliminary trials. Borchi® Kat 28 can be added to the polyol component of the coating system either in the supply form or diluted in a suitable solvent. Dissolved in organic solvents, Borchi® Kat 28 is only stable for a limited period of time. In polyurethane foam systems the recommended addition rate of Borchi® Kat 28 is between 0.05 and 0.20 % by wt. calculated on the total formulation depending on the kind of application. It must be determined in preliminary trials.

Storage & Handling
- Storage
- Protect from the effects of weathering and store at temperatures between 5 and 30 °C. Once opened, containers should be resealed immediately after each removal of the product. After opening the drums, a short-time consumption of Borchi® Kat 28 is advisable. Although maximum stability is ensured by special product stabilization, the active tin content might be reduced if Borchi® Kat 28 is exposed to air or stored unsealed or in drums with low filling level.
