December 2010 - Case Binding with PUR Adhesive:
The "Dream Team" for Strength, Flexibility and Cost Efficiency

Case-bound books are designed to last years or even a lifetime. But when spine flexibility, page-pull strength and cost efficiency are essential to your project's success, PUR adhesive is likely your most attractive binding solution. This "dream team" meets the needs of your most demanding book projects!

Why PUR?
PUR (polyurethane reactive) binding adhesives offer superior strength, flexibility and durability to standard EVA perfect binding glues. These advantages are especially valuable for books with heavy ink and coating coverage or - you guessed it - hardcover cases attached to them. The strength and durability of a hardcover case bound book is complemented by the strength, flexibility and long lasting hold of PUR glue.

Are there layout differences between perfect binding and PUR?
No. When planning layouts for your hardcover PUR bound book projects, the same guidelines apply as in perfect binding. Covers should have a four-page wrap endsheet similar to a perfect bound soft cover. These endsheets must be of a sufficient stock weight for best adhesion and strength; 80# uncoated stock is the recommended choice for best adhesion and stability in an endsheet. A two-page flysheet for both the front and back are optional. Case materials and decorative options are the same as well. Case bound PUR books can be foil stamped, embossed, UV coated or covered with a dust jacket; anything you can do to a traditional adhesive bound, hardbound book can be done here. The only change with PUR is the added strength to your book’s spine.
