Halogen-Free Background
Bromine and chlorine are known to emit toxic and corrosive gases when ignited. In 2003, standards created by the International Electromechanical Commission (IEC) were passed into law to eliminate concerns associated with end of life/disposal of devices containing these chemicals. Initial target areas include consumer electronics and household appliances.
The DYMAX Documented Halogen-Free Program
DYMAX Halogen-Free conformal coatings, encapsulants, potting compounds, and adhesives are documented by an independent laboratory to meet or exceed standards set forth in IEC 61249-2-21. This international directive defines halogen-free as <900 ppm for chlorine, <900 ppm for bromine and < 1500 ppm total level of both combined. The current test method used for certification is BS EN 14582:2007.
DYMAX halogen-free formulations have been the global standard for many years. We offer a wide variety of halogen-free conformal coatings, adhesives, potting materials and more to meet industry mandates without sacrificing performance requirements.
