Zinc Oxide is not listed in the ECHA Article 95 List, and I understand that is because its use is not authorized as component of a biocidal product.
If Zinc Oxide is not part of a biocidal product, (as in this case, it is part of an article and it is fully cured) then this regulation would not apply. As mentioned earlier by Vetty007, it depends on the function of the zinc oxide in the formulation. In my case it adds strength to the rubber compound.
Would this be correct? Thank you in advance.
