Borchi^® Kat 0244

Physical Characteristics

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 clearcoats
  • Automotive Refinish

Dosage

Our experience has shown the recommended addition rate of Borchi^® Kat 0244 to be between 0.01 and 0.03 % product,
calculated on solid binder. The exact amount depends on the used binder and should be determined by means of
preliminary trials. Borchi^® Kat 0244 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 0244 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.
