WHAT is PUR adhesive?

PUR stands for Polyurethane Reactive and refers to a very specific type of super aggressive adhesive that can be used when performing perfect binding. PUR adhesive was introduced to the market in 1989 and has continued to gain popularity. PUR is brought to a liquid state or “activated” by heat and “cures” through exposure to moisture in the air. Because of this chemical reaction; PUR bound books require a 24 hour “cure” time once bound prior to shipping, and will continue to gain strength “page pull” for up to 2 weeks after bound. PUR Binding has become the premier choice for perfect binding and manufacturing adhesive case bound books. The strength and longevity of PUR makes it an excellent high quality alternative to traditional smythe sewing and traditional EVA adhesive.
