PUR Adhesive Binding Equipment and Perfect Binding Samples PUR Adhesive Binding
PUR Adhesives differ from conventional hot melt glues in that they cure by crosslinking, via a chemical reaction, with moisture contained in the paper stock or surrounding air. Once cured, the adhesive's higher molecular weight provides a tough, pliable bond that is resistant to temperature extremes. PUR Adhesives deliver distinct performance benefits over typical binding adhesives, including:
  • Bond cross-grain, coated and recycled stocks
  • Improve lay flat characteristics
  • Resist temperature extremes from -45°F (-43°C) to 200°F (93°C) after cured
  • Decreased coating thickness by half that of conventional hot melts
  • Low application temperatures mean book block is subjected to less heat
  • Increase Page-Pull values
