  • Robust processes for higher quality and uniform finish.
  • Additional savings with no final seal required.
  • Low temperature saves energy.
  • Catepillar 1E 4093-B approved.
  • Meets the highest quality standards of John Deere.

Ad-Tech Industries, Inc. (Ad-Tech) was thrilled with the immediate improvements after converting to Chemetall's new Gardobond A 4002 iron phosphate technology. Steve Loritz, Operations Manager for Ad Tech, explains that Ad-Tech had very high expectations from the latest Chemetall line conversion. "We have been a Chemetall customer for 15 years, and any Chemetall customer knows that they set a very high bar. Chemetall impacts the one metric that is most important, the satisfaction of our customers. Chemetall’s philosophy of continuous improvement through collaboration fully aligns with our commitment to our customers."

Mr. Loritz continues, "This time was no exception; we immediately observed the very even conversion coating over the entire surface area with Gardobond A 4002. Further, it is easy to control, and provides noticeable improvements in corrosion protection and part finish and quality. Our key customers are happy that their specification requirements are being met so accurately and consistently."

The two 7-stage powder coat lines are the specific processes that benefitted from this recent technology upgrade. Powder coating line #1 process includes alkaline cleaning with Gardoclean® TP 10367 and laser-scale removal with a Chemetall acid pickle with Gardacid® P 4462/1, followed by the iron phosphate technology finish Gardobond A 4002. The smooth transition to Gardobond A 4002 on the powder coating line #1 was successfully completed in February 2019. The next milestone at Ad-Tech, was the conversion of the powder coating line #2 which was transitioned to Gardobond A 4002 in May of 2020.

Steve Loritz had more to say, "Chemetall has achieved the one metric for us that is always the most important. Chemetall helped our customers be happier with us! Gardobond A 4002 has been able to meet key customer specifications such as John Deere paint specifications and meet Caterpillar specifications without the use of a sealer. Added to this the seamless and easy transition. This is a true win-win."

Brian Groubert, Technical Account Manager for Chemetall, was equally enthusiastic, "This product is built so well that it continues to deliver the consistent coatings well into its bath life unlike other pretreatment iron phosphates in the industry which tend to break down faster. Furthermore, the wide process operating range of Gardobond A 4002 make it easy to use in just about any industry. Ad-Tech is now enjoying improvement in coating weights (previously about 50 mg/ft.2 to about 70 mg/ft.2 currently) without making any other changes to the line. All physical testing including salt spray and cyclic corrosion testing saw an improvement of 20–40%. We are thrilled."
