Hot melt bonding
Hot melt glue or PUR glue?
Our customers choose hot melt adhesive!
In cases where thick paper is used in the block (above 130 g / m2) and it is necessary to improve the opening of the block, a sewing-glue joint (thread + hot melt glue) or PUR glue is used.For comparison, the advantages of PUR glue include:
– Reliable – high adhesive strength. Sheets do not fall out during intensive use, they are used to fasten thick types of paper, catalogs with different inserts.
– Elastic – allows you to open the product 180 degrees, so the internal margins can be made smaller (comparable to – thread + hot melt glue).
– Resistant to high (+90) and low (-40) temperatures, solvents, oils (unstable hot melt glue).
The main disadvantages of PUR glue:
– Fully polymerized only after a day (hot melt within a few hours);
– The cost is approximately 2 times higher than hot melt glue;
– Vapors of PUR glue during the gluing process are toxic.The first experimental printing house – provides all possible options for gluing blocks: hot melt glue, PUR glue, thread + hot melt glue! Write, call! Always in touch!
