The appearance and versatility of perfect binding make it the
appropriate choice for many book binding projects. Some factors
that deter from this binding choice are Grain Direction,
Ink and Coatings, and Stiff Inserts.
Our answer to some of these problems is PUR (polyurethane) glue.
Perfect Binding with PUR has fixed many of projects over the years,
and is starting to become the glue choice specified by customers
that are in the KNOW.
If you are competing against another competitor, and need to
differentiate your product from that of the competition, then
educate your customer and sell them on the fact that you can have
their book bound with PUR. This product is far stronger than traditional
EVA glues, as documented and verified via Werner Rebsamen, Rochester
Institute of Technology-School of Printing. Call for a free copy
