Activating Water- based Adhesives

Medium Wave Quartz Infra red emitters are utilised by British United Shoe Machinery to accelerate the activation of polyurethane adhesive during the shoe manufacturing process

In normal air drying circumstances the drying took 20-30 minutes, this has been reduced to a 1.5 minute cycle for both sole and upper utilising a combined convection and infra red system to activate the adhesive prior to the bonding

The process ensures a dependable bond between the upper and sole and reduces work in progress and manufacturing area
