Crosslinker for the formulation of heat curing PUR coatings
Blocked VESTANAT® polyurethane crosslinkers offer solutions for interior as well as exterior coating applications within the can and 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
