Gas Flames are in fact very hot gases in a state of plasma. Gases in the secondary flame envelope are not fully combined, and include free radical species. If this secondary flame envelope is brought into contact with the surface of plastics, the free radicals react with the plastic chain molecules and create additional chemical bond sites that increase the surface energy level or Dyne level of the plastic surface. This results in improved adhesion of water based adhesives and coatings, and improved bond strength after curing can be achieved. The surface treatment effect is semi-permanent, non-polluting, fast, efficient, and safe. It has several advantages over electric systems - guaranteed single side treatment, no production of Ozone, lower operating and capital costs, and high dimensional flexibility due to large treatment zone in front of the burner.
