Borchi^® Kat 24

• Replacement for other polyurethane catalysts, especially 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
• Higher film hardness
• Earlier sanding of the coating

• Solvent-based one- and two-component polyurethane coatings
  • Automotive Refinish
  • General Industrial
  • Coil

Our experience has shown the recommended addition rate of Borchi^® Kat 24 to be between 0.01 and 0.12 % product, calculated on total solid binder. The exact amount depends on the used binder and should be determined by means of preliminary trials.

Borchi^® Kat 24 can be added either in the supply form or diluted in any suitable solvent (e.g. butyl acetate) to the polyol component of the coating system. Borchi^® Kat 24 should not be diluted below 10 % of the supply form, since those solutions are only stable for a limited period of time.

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.
