Printed books are still popular despite the rise of E-books. The Association of American Publishers says that paperback and hardback book sales are growing while e-book sales fell by 18.7 percent during the first nine months of 2016. However, printed books offer challenges for adhesives to overcome. The adhesive used to bind a book must be durable and remain flexible, and if it is fast-drying, it makes the book printer’s work much easier.
Polyurethane adhesive for bookbinding are comparative newcomers to this niche but are gaining popularity thanks to the advantages they offer. Firstly, they have a lower melting-point than other types of bookbinding adhesive, and secondly, although they have a curing time of 24 to 48 hours, they meet the need for a high-quality, flexible bond that will allow book-lovers to enjoy their books for years to come. Finally, polyurethane adhesive resists temperature fluctuations and moisture, is compatible with both hard and softback books, and can be used on almost any type of paper.
