Are repairs made with super glue safe to use in microwave ovens?
On One Hand: Super Glue is FlammableSuper glue–the common name for cyanoacrylate adhesives–is highly combustible. When heated, super glue becomes unstable and gives off hazardous fumes, according to the Occupational Safety and Health Administration, which produces a Material Data Safety Sheet on these kinds of adhesives.On the Other: There are Microwave Safe AdhesivesSeveral adhesive manufacturers produce non-toxic, microwave-safe glues. These adhesives are appropriate for repairing most cookware material, including ceramics, glass and plastics. Microwave-safe glue may be used to make cosmetic repairs to external, non-mechanical components of the microwave and as a temporary fix to the appliance’s rotating glass tray before it is replaced.Bottom LineNeither super glue or microwave-safe glues should be used for interior repairs to a microwave. The Material Safety Data Sheet for cyanoacrylate adhesives specifically warns against exposing super glues to heat.
