What is it?

Epoxy resins are used primarily as two-component adhesives systems (monomer and hardener).

How can I avoid it?

Patients sensitive to Epoxy Resin are probably reacting to the uncured resin of a two-part adhesive or glue system (monomer and hardener), paints or other coatings that have to be mixed shortly before use. If this occurring at home, patients should switch to non-epoxy resin glues or adhesives. If this occurring at work, patients should be instructed to never allow the adhesive or coating to contact the skin. If the face is involved, it is probably due to fumes from the adhesive curing process, and such an operation should be performed in a closed system (so that the fumes do not come into contact with the skin) and protective clothing worn, including heavy vinyl gloves. Allergic patients should also consider (if allowable) switching to a higher-molecular-weight epoxy resin, which is less sensitive, or to a non-epoxy adhesive.

Since Epoxy Resin is present in some vinyl or plastic products, allergic patients should be made aware of the finished products in the list below as possible sources of reactions. Such patients should warn their dentists that they are allergic to Epoxy Resin. Patients with Epoxy Resin allergy may be protected by the use of heavy-duty vinyl gloves (rubber and nitrile gloves allow epoxy penetrations).
