When working with difficult papers, slow-to-medium setting adhesives deliver better adhesive penetration between pages and onto the cover. Fast-setting products typically are used for high-speed magazine lines when the paper quality is easier to adhere to. The viscosity of the adhesive you choose also is relevant. Higher-viscosity products exhibit improved strength and heat resistance, whereas lower viscosity products can improve pot stability and machining characteristics.
Low-application-temperature (LAT) hot melts, typically applied at 250-275°F, have gained popularity for paperback, magazine, catalog, and other perfect-binding applications. This unique type of adhesive offers advantages over conventional (350°F) application products, including:
LAT hot melts do not compromise strength and flexibility. Both page-pull and page-flex values rival those of their 350°F counterparts. LATs also can deliver significant cost savings through lower energy consumption. H.B. Fuller has a complete line of LAT hot melts to satisfy one-shot, perfect-binding applications. These hot melts are versatile and bond to many substrates, including papers with a high percentage of recycled content or modified with additional fillers and sizing agents.
