PUR (Poly Urethane Reactive) – the most agressive adhesive used in commercial binding applications, providing superior page pull strength. Works great with uncoated or coated stocks, even cover stock with coatings or synthetic materials such as book cloth, plastic or UV coating. PUR has a lower freeze point and a higher melting point than all other adhesives used in book binding.
PUR adhesive works well on all types of paper, even aqueous coated stocks or books printed with heavy ink coverage or uncoated papers. This is of enormous benefit to projects requiring short run digitally printed books on highly coated or varnished interior pages – even synthetic materials.
