Cow­boys – ‘crit­i­cal’ chal­lenges for coat­ing in­dus­try

DEMM Engineering & Manufacturing - - INDUSTRIAL COATINGS -

The Aus­tralasian In­sti­tute of Sur­face Fin­ish­ing (AISF) says the pow­der coat­ing in­dus­try is fac­ing crit­i­cal chal­lenges of qual­ity caused by poor process con­trol, and a lack of in­dus­try knowl­edge.

“By tak­ing short­cuts in the pre-treat­ment pro­cesses, th­ese ‘cow­boys’ are cre­at­ing doubts about the ca­pa­bil­i­ties of pow­der coat­ing as a vi­able pro­tec­tive coat­ing,” says the in­sti­tute.

“Most fail­ures of­ten re­sult in ex­pen­sive liti­gious out­comes and a re­liance on war­ranties that may not nec­es­sar­ily cover the full cost of rec­ti­fi­ca­tion.”

The or­ga­ni­za­tion says that many high qual­ity ap­pli­ca­tors in Aus­tralia have been in­ad­ver­tently im­pacted by the pow­der coat­ing in­dus­try’s ex­ist­ing self-reg­u­la­tory ap­proach.

“Good op­er­a­tors com­plain that their rep­u­ta­tion is also tar­nished by the poor per­form­ers, whose work in the field dis­plays a de­te­ri­o­ra­tion of work­man­ship, qual­ity and per­for­mance that can be di­rectly at­trib­uted to a lack of con­sis­tent and mon­i­tored com­pli­ance mea­sures,” it claims.

AISF’s Fed­eral pres­i­dent Peter Mal­lios says there are more than 1000 pow­der coaters in Aus­tralia with only a few hav­ing pre­treat­ment sys­tems suit­able for alu­minium. Most of the pow­der coaters, he says, sim­ply coat over all types of metal with­out any real knowl­edge of the cor­rect pro­cesses, “ru­in­ing the rep­u­ta­tion of the in­dus­try”.

He says: “While pow­der coat­ing is com­monly per­ceived as an easy task, any pro­fes­sional coater would know that it takes a lot more than just pulling a trig­ger on a spray gun to pro­duce good qual­ity fin­ished parts con­sis­tently and ef­fi­ciently, which also meet per­for­mance cri­te­ria and ex­po­sure class spec­i­fi­ca­tions.”
