Features

  • Replacement for other polyurethane
    catalysts, especially for tertiary amines and DBTL
  • Accelerates the chemical reaction between the alcohol and
    isocyanate component of polyurethane coating systems,
    thus allowing optimum steering of the drying properties
  • Ensures fast blocking stability
  • Reduced yellowing
  • Higher film hardness

Applications

  • Solvent-based two-component polyurethane clear coats
    • Automotive refinish

Dosage

Our experience has shown the recommended addition rate of Borchi® Kat 0243 to be between 0.02 and 0.15 % product,
calculated on solid binder. The exact amount depends on the used binder and should be determined by means of
preliminary trials. Borchi® Kat 0243 can be added as supplied or solved in any suitable solvent (e.g. 10 % in xylene) to the
polyol component of the coating system. The solution has to be homogenized by stirring. Borchi® Kat 0243 is also soluble in
polar solvents and solvents of medium polarity. However, these solutions are only stable for a limited period of time.

Storage

Protect from the effects of weathering and store at temperatures below 50 °C. Once opened, containers should be resealed immediately after each removal of the product.
