Provichem® 1102 is a very effective, fast curing trimerization catalyst for the preparation of rigid polyisocyanurate (PIR) foams


  • It displays strong catalytic activity in trimerization of isocyanates. This leads to the formation of isocyanurate groups, bringing about additional cross-linking of the polymer.
  • Provichem® 1102 is a low odour catalyst, and is free of amino groups and glycol solvents.
