What are Halogen-free Epoxy Coating Powders?

The Euro­pean (RoHS) and Japan­ese (JIG) guide­lines rec­om­mend con­trols on halo­genat­ed com­pounds. The rea­son is envi­ron­men­tal as these are believed to release diox­ins (tox­ic by-prod­ucts) once they are burned which has also been linked to the increase risk of cancer.

What elements are considered halogens?

Halo­gens are the ele­ments found in group or col­umn VIIA of the Peri­od­ic Table of the Ele­ments and include:

  • Flu­o­rine (F)
  • Chlo­rine (Cl)
  • Bromine (Br)
  • Ion­dine (I)
  • Astat­tine (At)

As it con­cerns epoxy coat­ing pow­ders, or epoxy mold­ing com­pounds, halo­gens have been his­tor­i­cal­ly used as the ingre­di­ents in the flame retar­dant por­tion of the for­mu­la­tion which typ­i­cal­ly includ­ed bromines. In cas­es where there are no flame retar­dants, there are no halo­gens as in the case with epoxy coat­ing pow­ders for motor irons or bus­bars, where the met­al mass is so large as to not require flame-retardants.

Test Method TM EN 14582 Solids Extraction per IPC TM 2.3.34

Var­i­ous stan­dards exist that give a def­i­n­i­tion of halo­gen-free mate­ri­als including:

  • JEITA ET-7304
  • IEC 61249–2‑21

Though the require­ment is slight­ly dif­fer­ent in each stan­dard, they all refer to Test Method TM EN 14582 Solids Extrac­tion per IPC TM 2.3.34 and they all agree that if a mate­r­i­al con­tains less than 900 ppm (parts per mil­lion) each or a total of less than 1500 ppm of bromine and chlo­rine, then a mate­r­i­al is con­sid­ered to be halogen-free.

CAPLINQ offers halogen-free Epoxy Coating Powders

CAPLINQ does still offer halo­gen-con­tain­ing mate­ri­als for cus­tomers who have not made the switch to halo­gen-free epoxy coat­ing pow­ders, but also offers Halo­gen-Free Func­tion­al Epoxy Coat­ing Pow­ders for cus­tomers who have made the switch to halo­gen-free products.
