Dillon Bindery: Extra Strength PUR Perfect Binding
In 2008 Dillon Bindery has once again invested in new equipment and technology. Dillon Bindery is the first Trade Bindery in Wisconsin offering high speed and large run PUR Binding.
PUR adhesive has established itself as a viable alternative to many other binding adhesives in the industry. It is a very useful tool, adding additional performance and a solution to ever increasing paper changes.
In most cases PUR is used to enhance the performance of page pulls and flexes to make a stronger book. A variety of factors influence the ability of an adhesive to perform.
- Paper with cross-grain significantly reduces page pull
- Length of paper fibers can drastically affect the strength of books. Short fibers from recycled paper reduce the ability of an adhesive to bond to pages
- Coated stocks, clay, Aqueous coating, Varnish and/or UV coatings can be difficult surfaces to bond
- Signature thickness and mixed paper stock can add stress to the glue line
- Proper spine preparation (exposing maximum amount of fibers)
- Residual print solvents in the paper
PUR bound books will have higher performance levels than similarly bound books using standard hot-melt (EVA)
- The thin, tough and flexible nature of PUR enables the pages to open easily and have lay flat characteristics.
- PUR is resistant to a variety of inks and solvents. In today’s printing industry jobs are rushed. Residual solvent can migrate into the glue line which can cause an EVA hot-melt to fail. Rebinds can be very expensive. PUR can eliminate this risk.
- PUR’s resistance to temperature extremes provides benefits during shipping and storage. Books stored in cars or containers are typically unaffected.
Why must I wait 24 hours for a cured book?
The benefits of PUR require a change of mindset. PUR is a 100% solid moisture-curing adhesive. Depending on the available moisture, 24 to 72 hours of curing time are not unusual
