Crosslinker for the formulation heat curing PUR coatings

Blocked VESTANAT® polyurethane crosslinkers offer solutions for interior as well as exterior coating applications within the can- & coil coating industry.

Blocked polyurethane crosslinkers in thermosetting 1K systems

  • Contains blocking agents e.g. -caprolactam
  • At ambient temperature: blocked polyurethane crosslinkers cannot react with the resin component
  • At elevated temperatures: the blocking agent will be released and the isocyanate group can react with the resin
