In for a Treat

Corona treaters remain popular for reasons that likely extend from familiarity to versatility to economics—but gas flame treaters aren't without an established niche. "Despite some of the known advances of flame treaters, I believe corona treaters will remain in the forefront," states Marc Nolan, sales manager at Sherman Treaters, Ontario, Canada. "People have reservations with the concept of a naked flame in the middle of their facility. In extrusion coating, it is common to see flame as a pretreater and corona in a post-treating role."
