PB485 comprises an unsupported rubber resin adhesive extruded onto a release paper in the form of an easy-to-apply roll. PB485 provides a fast, clean and highly versatile method of forming a permanent and flexible bond between two substrates without the need for priming, mixing or curing of liquid adhesives. PB485 will form a near-immediate bond to a wide range of substrates, including metals, plastics and ceramic materials. PB485 is amber in colour, and available in widths from 6mm to 25mm.
