Seidl's Bindery — Lone Star Finisher

"PUR is the strongest, most flexible and versatile binding adhesive available," he declares. "Those properties have also made it popular for use in automobiles and aircraft, which should give you a good indication of how well it holds books together. The page pull strength of a PUR-bound book is more than two-and-a-half times that of a standard perfect-bound book using EVA (ethylene vinyl acetate) adhesive. Books bound with PUR adhesive simply will not fall apart, even under heavy usage in the most demanding conditions."
