What is Repair Plastics make up?
Repair Plastic is an industrial version of Dental Acrylic that has been modified to result in easy handling. After it has reacted and is hard, it is not soluble in water and if any monomer were left over to leach out into the water, it would be so little that its effect would be nil. Remember that very similar Acrylics are used inside the human body with hip joint replacement and dentures.
