PUR Adhesive Binding

PUR Adhesives differ from conventional hot melts 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.

• 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 curing
• Decreased coating thickness by half that of conventional hot melts
• Subject the book block to less heat with low application temperature
• Increase Page-Pull values
