Advantages of Using PUR Adhesives

It is no secret that (PUR) Adhesives or Reactive, polyurethane adhesives are a far more superior glue compared to Ethylene Vinyl-Acetate (EVA) adhesives.  Many companies have preferred to use EVA glues in the past because it was a far cheaper alternative. What countless companies do not realize is over the years PUR adhesive prices have been dropping, and the advantages for the now small price difference is significant.

Reactive, polyurethane (PUR) adhesive was specifically created for different bookbinding applications and can bind varnished, UV-coated, carton, mylar, recycled papers, woodworking, and other difficult stocks that require a special type of adhesives.

  • This type of adhesive will polymerize when applied in order to form a much stronger bond than a traditional hot melt.

PUR adhesives are strong, flexible, and once cured can withstand temperatures ranging from -40°F to over 140°F.

Additional advantages of PUR adhesives include:
  1. The ability of a PUR-bound book to lie flat when open.
  2. Impervious to print oils used in the digital print process and binding quality is unaffected by ink migration into the spine.
  3. Quick achievement of final bond strength.
  4. The page pull strength is approximately 50% better compared to standard and EVA hot melt.
  5. Excellent shelf life.
  6. Environmentally friendly.
