Binks 460 for Cold-End Coating during Glass Container Production

With ever increasing line speeds during the glass container production and bottles becoming increasingly lighter, there is a definite necessity for surface treatment. Glass containers are usually cold-end coated to protect (i.e. higher scratch

resistance) and lubricate the container allowing them to move smoothly, without damage and with high-speed handling equipment. Here the automatic spray gun Binks 460 has become well established, and more in demand than ever.

When cold-end coatings were introduced to the market, many different materials were used such as soaps, waxes (including beeswax), stearates, silicones, glycerides, and oleic acid. Today, waterbased poly(ethylene) emulsions are widely used. These emulsions are usually applied by traversing spray systems. Due to the small and lightweight design (only 200 gram) the gun is very suitable to be operated in such cold-end traversing spray systems. The gun has to work in a harsh and hot environment, as the “cold-end” is not cold at all, with the bottle temperature ranging from 66° to 177° C. And the different available nozzle sizes ( 0.5, 0.75, 1.0 and 1.5mm) allow to spray and fine atomization of almost any coating material.
