Condition
Food contact
The repaired surface touches food or drink, so the cured adhesive must be food-safe.
What to do
Working with it
- Only an explicit statement counts here: “FDA approved for indirect food contact” or an equivalent line in the manufacturer's own documentation.
- Indirect contact is not the same as direct. A cutting-board glue line is legal because the glue sits inside the board, not on the cutting surface.
- When nothing on the label says food-safe, repair the piece and retire it from food use. There is no way to make that call from the chemistry alone.
Questions
Common questions
- Does nontoxic mean an adhesive is food-safe?
- No. Nontoxic language usually describes ordinary handling or incidental exposure, while food contact is a separate documented use. Rely on an explicit food-contact statement for the cured product and the way the joint will be used.
- What is the difference between direct and indirect food contact?
- Direct contact means food touches the adhesive itself. Indirect contact means the cured glue is contained inside an assembly, such as a tight glue line, with no intended contact at the usable surface.
- Can I make an unapproved adhesive food-safe by coating over it?
- Do not assume so. Coatings can wear, crack, or leave an exposed edge, and the combined repair has not gained an approval that neither product documents. Use a system whose intended food-contact use is stated by its maker.
- What should I do if I cannot verify the adhesive used on a food item?
- Keep the repaired object away from food and drink. It may still be useful as decoration or storage for non-food items, but uncertainty about the cured adhesive is enough reason to retire it from food service.
