Comments from EliChem
Lately a lot of customers have asked whether a resin that is ASTM-certified as non-haz and not highly toxic is also by definition FDA-approved.
Well, ( in true economist fashion ) I’d have to say Yes and No.
Why “No” ? : Just because a resin has been tested by a toxicology lab and is found to conform to ASTM D-4236 ( non-haz and not highly toxic ) that doesn’t mean it is perfectly safe for use in all food contact applications.
We could use inventive wording to create the impressions of FDA-approval for example ” as per FDA regulations “, or ” conforming to FDA regulations ” however there is no substitute for the actual FDA test report and certificate number clearly stating the supplier name, the date of the report and identifying the resin brand concerned.
We don’t have this certificate. Perhaps request it from your supplier if they make any FDA claim.
Why “Yes” ?. Well, interestingly enough there is a proviso in the FDA regulations that mentions contact with materials made of or containing epoxy resins ( Epichlorohydin content formulations ) which states there is no food safety concern.
However if your coated area will be used for more than just incidental contact then check first and we will advise as best we can.
