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
  • Improved solvent resistance
  • Higher film hardness
  • Earlier sanding of the coating

Applications

  • Solvent-based one- and two-component polyurethane clearcoats and pigmented coating systems
    • Automotive Refinish
    • General Industrial
    • Coil

Dosage

Our experience has shown the recommended addition rate of Borchi® Kat EP1 to be between 0.01 and 0.04 % 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 EP1 can be added either in the supply form or diluted in any suitable solvent (e.g. butyl acetate, xylene, methoxypropylacetate) to the polyol component of the coating system. The solution has to be homogenized by stirring.

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.
