What is PUR BINDING

PUR Binding is a form of perfect binding, where the pages and cover are glued together at the spine and the other three sides of the book are trimmed as needed to give them clean “perfect” edges.

Polyurethane Reactive (PUR) is the most durable book binding glue available. It is far superior to Ethylene Vinyl Acetate (EVA) or any other adhesives used in traditional perfect binding.

The Main Benefits of PUR Binding include…

1) PUR has superior flexibility, which prevents the spine from cracking when the book is opened wide or pressed down flat.

2) Compared to EVA adhesive, PUR offers 40% to 60% better resistance to page pull-out. In fact, it is nearly impossible to pull a page out of a book bound with PUR adhesive.

3) PUR can adhere to a wide variety of substrates, including ink, varnish, recycled paper, mylar, and UV-coated or aqueous-coated stock.

4) PUR’s performance and structural integrity is unaffected by extreme cold or hot environments (-40º to 200º Fahrenheit).

5) Because PUR is so strong and pliable, less adhesive is needed to firmly bind the cover and pages. Less glue means less distortion of the spine’s shape, resulting in a crisp, square appearance…even on thinner books.
