August 2008 - PUR Glue: The Strongest on the Market

Strength, flexibility and durability. If those are the attributes you need in a book binding adhesive, then PUR (polyurethane reactive) adhesive is the glue for you. PUR works with challenges such as coated stocks, heavy ink coverage and cross-grain stocks. There’s no question- PUR can bind them all!

Muscle Bound Bindery is adding PUR adhesive binding to its lineup of services which is considered the most durable book-binding adhesive available on the market. Regardless of the book-binding task, PUR glue delivers the most strength over other adhesives. This makes PUR glue an ideal solution for coffee table books and library reference materials that see repeated use. Whether books are thick, thin, frequently used or roughly treated, those bound with PUR glue withstand the test of time.

PUR glue is used to produce a variety of softcover books as well as hardcover PUR adhesive books. PUR has superior page pull that’s well-suited for products enduring repeated use. It’s more flexible and more pliable than traditional EVA hot-melt (ethylene vinyl acetate) glue so books tend to lie flatter than books made with hot-melt glue.

PUR Advantages

Here are a few additional details about the advantages of PUR adhesive for your consideration:

• Books bound with PUR glue will withstand the rigors of heavy usage, such as textbooks and children’s books, even in the most demanding conditions. Consider choosing PUR adhesive to bind products that receive repeated handlings, such as catalogs, directories and manuals.

• The composition of PUR glue enables it to form a strong bond with the paper even in the presence of inks and coatings. This is in contrast to standard perfect binding, where most coatings must be kept free from the spine area to ensure a strong bond.

• PUR glue is impervious to temperature extremes. Once it has cured, PUR remains stable in temperatures ranging from -40 degrees F to over 140 degrees F. That means PUR-bound books can be used anywhere without unwanted remelting or cold cracking.
