About PUR = PolyUrethane Reactive /
What is PUR Glue
PUR adhesives differ from EVA hot melts in
the way cure, crosslinking via a chemical reaction with moisture
contained in the paper stock or surrounding air. Once cured, the
adhesive's higher molecular weight provides a tough, pliable bond
that is resistant to temperature extremes.
Advantages of using PUR for Perfect
Bound Books
Less Adhesive Up
to one third the glue coating thickness of conventional hot melts
Excellent Lay-flat
The fact the PUR is considerably more
flexible and a thinner coating of glue is used (than standard EVA
hotmelts) results in excellent lay-flat results
Bond Strength
A high pull
strength or bonding is easily achieved, in some case the page pull
strength of a PUR-bound book is more than 2.5 times that of a
standard perfect-bound book using EVA
Creep
Resistance
Due to the high
bonding strength of PUR both the inside pages and covers of the
book retain the original shape with the cover not moving or
creeping away from the spine, causing the book to look unsightly.
Temperature Resistant
PUR glue has an excellent resistance to changes in temperature,
books subject to temperture ranges -40° - 200° Farenheit, are
still flexible and show no sign of damage to the glue on the spine
Chemical Resistance
PUR glues are not affected by chemicals |
