SunDance Increases Bookbinding Portfolio with Perfect Binder BQ-470
The BQ-470 is a fully automated 4-clamp binder that features an interchangeable glue tank for both PUR and EVA adhesives. Polyurethane reactive (PUR) hot melt adhesive is known for its binding strength and eco-friendliness whereas ethylene-vinyl adhesives (EVA) are a popular and affordable hot melt adhesive but has more limited capabilities. EVA has difficulty binding coated stock firmly and doesn’t yet enable acceptable lay-flat binding. PUR, on the other hand, can provide adequate binding strength and lay-flat quality for books.
