Why Specify Polyurethane Reactive (PUR): Features, Advantages and Benefits:

Available Only on the Muller Martini Corona C12

PUR glue reacts with moisture to cross-link molecules for improved performance characteristics. PUR is recommended for use in binding of materials with heavy ink coverage and/or bleeds, heavy use (e.g. reference materials, catalogues, cook books, art books, etc.), wrong grain paper stocks, heavyweight papers and/or specialty papers such as synthetics, plastics, art papers, etc.
PUR provides a binding at the spine that is even stronger and more durable than traditional hot melt.

• Glue sets in seconds, is structurally rigid very quickly, and continues to cure over time.
• Page pulls and flexes are far superior to hot melt glues. Overall book flexibility is enhanced as adhesive is only half as thick as hot melt.
• Problem of ink migration at the spine is eliminated as solvents and volatiles in the ink cannot break down PUR glue.
• PUR is applied at cooler temperatures than hot melt and therefore cross grain book stocks are less likely to go ‘wavy’ at spine.
• Crack resistant, even with extreme cold weather conditions. Pages won’t fall out. Glue is heat resistant. PUR won’t ‘melt’ under extreme heat conditions, unlike conventional hot melt glue.
• PUR works well with coated and uncoated papers.
